Introduction

“There is a perfect gradation between sound people and insane”: Gruber, “Darwin on Man,” quoted in Roy Porter, Mind Forg’d Manacles: A History of Madness in England from the Restoration to the Regency (London: Athlone Press, 1987), 37, 268.

Chapter One: The Tail Tip of the Iceberg

This idea of animals as machines: William Coleman, Biology in the Nineteenth Century: Problems of Form, Function and Transformation, Cambridge Studies in the History of Science (Cambridge, UK: Cambridge University Press, 1978), 121–22.

identifying humanlike emotions or consciousness in other animals: Lorraine Daston and Gregg Mitman, eds., Thinking with Animals: New Perspectives on Anthropomorphism, new ed. (New York: Columbia University Press, 2006).

He believed that the similar emotional experiences of people and other creatures: Mental illness is also a key part of Expression because Darwin thought that the insane (as he called them) were a purer source for the study of emotion. Like any good Victorian he was preoccupied with all manner of social mores and inhibitions, and he felt, perhaps rightly, that many people in insane asylums had been loosed from the shackles of proper emotional control and expressed themselves more authentically.

Yet Darwin did not see these people as morally bankrupt, as many physicians of his time did. Instead he saw the insane as simply not self-conscious, as unaware of themselves and lacking an idea of self. Since they weren’t self-conscious, they couldn’t embarrass themselves and thus were unchecked in their expression of emotion. This, Darwin believed, made the insane into perfect study subjects for what despair, anger, fear, and more really felt and looked like. And so he devoted a lot of space in his book to covering the phenomenon of insanity in human beings, discussing such things as upset mentally ill humans raising the hair follicles on their heads just as dogs do their hackles (this last point not having withstood the test of observation) and poring over photos of people in insane asylums. Janet Browne, “Darwin and the Expression of the Emotions,” in The Darwinian Heritage, ed. David Kohn (Princeton, NJ: Princeton University Press, 1985), 307–26.

“with the manner in which she then tried”: Charles Darwin, The Expression of the Emotions in Man and Animals (London: John Murray, 1872), 120.

“Not far from my house”: Ibid., 58, 60.

“a peculiar short snuffle”: Ibid., 129. Darwin may not have observed happy pumas or tigers himself. Nor had he seen crying elephants. Instead he relied on letters and published observations of people who had, coupled with his own careful observation of the animals he lived among, saw in his travels, and observed at the Regent’s Park Zoo.

“Man and the higher animals”: Charles Darwin, The Descent of Man, and Selection in Relation to Sex (London: John Murray, 1874), 79.

Darwin doesn’t seem to have done any original research: This is based on searches performed in 2010 and 2011 in the Darwin Correspondence Project (http://www.darwinproject.ac.uk/), as well as personal communication with Janet Browne and David Kohn in 2009–10 and careful readings of citations in Darwin’s published works.

“I hope to prove that”: Richard Barnet and Michael Neve, “Dr Lauder Lindsay’s Lemmings,” Strange Attractor Journal 4 (2011): 153.

Lindsay believed that the minds of insane people: W. Lauder Lindsay, Mind in the Lower Animals, in Health and Disease, vol. 2 (New York: Appleton, 1880), 11–13.

Lindsay also wrote about feral children: Ibid., 14.

Insane humans were also compared to: Porter, Mind-Forg’d Manacles, 121–29.

some of the incurables “are kept as wild beasts”: John Webster, Observations on the Admission of Medical Pupils to the Wards of Bethlem Hospital for the Purpose of Studying Mental Diseases, 3rd ed. (London: Churchill, 1842), 85–86.

He was even convinced that some human lunatics: Lindsay, Mind in the Lower Animals, 18–19.

studies of hormonal fluctuations in baboons: Jonathan Balcombe, Second Nature: The Inner Lives of Animals (New York: Palgrave Macmillan, 2010), 47.

A number of recent studies: Jason Castro, “Do Bees Have Feelings?,” Scientific American, August 2, 2011, http://www.scientificamerican.com/article.cfm?id=do-bees-have-feelings; Sy Montgomery, “Deep Intellect,” Orion, November–December 2011, http://www.orionmagazine.org/index.php/articles/article/6474/; “What Model Organisms Can Teach Us about Emotion,” Science Daily, February 21, 2010, http://www.sciencedaily.com/releases/2010/02/100220184321.htm; Balcombe, Second Nature.

The results of these studies are changing debates: There have been some distinctions made within the neurosciences and affective sciences more generally about the differences between “emotions” and “feelings.” Antonio Damasio and Joseph LeDoux, for example, have argued that emotions are not necessarily conscious states, while feelings may be, and are the result of our minds trying to make sense of emotions. See, for example, Antonio R. Damasio, Descartes’ Error: Emotion, Reason, and the Human Brain (New York: G. P. Putnam, 1994), 131–32, 143.

As the neurologist Antonio Damasio has argued: Ibid.

“I think that emotions—although they are subject to selection”: Lori Marino, personal communication, May 4, 2011.

The ethologist Jonathan Balcombe believes that emotions: Balcombe, Second Nature, 46.

the only animals to have been proven self-aware: Although this is slightly different, I have never known a dog to be confused by his or her reflection in a mirror, sliding glass door, or the glossy surface of an oven. Perhaps some dimwitted dogs do bark or sniff at the reflection, but most don’t. While this doesn’t prove that they see the reflected dog as themselves, it doesn’t prove that they don’t.

African Grey parrots will use mirrors as tools to gather information about where food, toys, or playmates are, but they don’t necessarily groom while looking at their reflection. A parrot may recognize herself but might care to do something else with the information contained in the mirror (for instance, that a human it knows is busy making a fruit salad behind her). Even among the great apes, the degree to which chimpanzees identified themselves in mirrors depended on the individual chimpanzee. The same held true with gorillas. D. M. Broom, H. Sena, and K. L. Moynihan, “Pigs Learn What a Mirror Image Represents and Use It to Obtain Information,” Animal Behaviour 78, no. 5 (2009): 1037; I. M.

Pavlov became interested in canine neurosis: According to Breuer, Anna’s hysteria symptoms included (among other things) partial paralysis of her limbs, weakness, loss of motion in her neck, a nervous cough, lack of appetite, hallucinations, agitation, mood swings, destructive behavior, amnesia, tunnel vision, odd speech patterns (in which she did not conjugate verbs), and difficulty speaking German (but was still able to translate German texts into English). John Launer, “Anna O and the ‘Talking Cure,’ ” QJM 98, no. 6 (2005): 465–66; G. Windholz, “Pavlov, Psychoanalysis, and Neuroses,” Pavlovian Journal of Biological Science 25, no. 2 (1990): 48–53.

The lab performed endless variations: Michael W. Fox, Abnormal Behavior in Animals (Philadelphia: Saunders, 1968), 81; Windholz, “Pavlov, Psychoanalysis, and Neuroses.”

Pavlov’s views on the similarities: Fox, Abnormal Behavior in Animals, 85, 119.

Pavlov had his critics: H. S. Liddell, “The Experimental Neurosis,” Annual Review of Physiology 9, no. 1 (1947): 569–80.

argued that Pavlov’s work was inferior to analysis: In 1929 one Viennese psychoanalyst argued that Pavlov’s work was far inferior to analysis when it came to understanding neurosis in humans. Pavlov countered that neurosis in both people and other animals was rooted in the collision of excitation and inhibition (the basic processes he was testing in the lab) and that if his dogs could speak they would most likely say that they could not control themselves and so they did what was forbidden and were punished. But none of these verbal dog reports, Pavlov continued, would add anything new to the knowledge gained from the experiments themselves. Windholz, “Pavlov, Psychoanalysis, and Neuroses”; Liddell, “The Experimental Neurosis.”

his ability to return his dogs to their normal, nonneurotic state: He may have changed his mind somewhat. A few years later, while working with humans at a clinic focused on nervous diseases, Pavlov began to put far more stock in the process of psychoanalysis, at least when it came to understanding humans, and he spent the last few years of his life researching the causes and manifestations of what were then the nervous diseases of hysteria, neurasthenia, and psychasthenia in people. Windholz, “Pavlov, Psychoanalysis, and Neuroses”; Liddell, “The Experimental Neurosis.”

These ideas were adopted by the military: Liddell, “The Experimental Neurosis.”

Pavlovian ideas of conditioning and deconditioning: Other animals are part of this story as well, as is the idea of “traumatic memory,” which was sometimes seen as related to nervous disorders. Our modern concept of traumatic memory dates back to the years leading up to World War I, stemming from experiments like Pavlov’s, but also, in part, to the earlier work of two American physicians, George Crile and Walter Cannon, and their experiments on cats and dogs. One of their research foci was on nervous shock. Crile and Cannon believed that extreme fear could cause physical problems similar to surgical shock in both humans and cats (a potentially lethal condition that left surgical patients pallid, faint, cold, anxious, and with a weak pulse, among other symptoms). Cannon’s experiments on felines, in which he destroyed the connection between the cat’s cortex and the rest of its nervous system, caused an extreme emotional reaction that looked a lot like fearful arousal: the cats’ hair stood on end, sweat seeped from their toes, their heart rate and blood pressure spiked, and they eventually collapsed and died. Cannon called this “sham rage” and used the cats’ experiences to explain the deaths of men who had been exposed to severe emotional shocks.

Doctors treating soldiers in the wake of World War I: More recently, evolutionary psychologists have argued that today’s PTSD may be an extreme adaptive behavior; that is, the soldier’s harrowing response to the horror he witnessed could be an unconscious attempt to keep himself away from war in the future. I believe this is an oversimplification of a complex reaction to trauma and anxiety.

One small dog, for example, discovered with a pig: “Wreck in Midocean; a Mad Dog and a Little Pig the Sole Occupants of a Brig,” New York Times, March 9, 1890.

Animals could also go mad from a lifetime of abuse: “ ‘Smiles,’ the Big Park Rhinoceros: Bought at Auction for $14,000, She Needs Constant Care, Although She Has an Ugly Temper,” New York Times, March 29, 1903.

Maddened horses, as they were known: “Dragged by Mad Horses: A Lady’s Dress Catches in the Wheels.

As late as the 1920s and 1930s: On the set of a 1930s Paramount film being shot in the Santa Monica Mountains, actress Dorothy Lamour was attacked by a “mad ape” (the film’s chimp actor, named Jiggs) and saved by a young man from the props department. A few years later a second mad monkey was on the loose in the Los Angeles suburb of Tarzana and ended up caged after its exploits ended in one angry neighbor’s garage. “Mad Cats in Madder Orgy,” Los Angeles Times, May 2, 1924; “A Mad Cow Mutilates Two People,” Los Angeles Times, May 19, 1889; “Color of Mad Parrot Saves It from Death,” San Francisco Chronicle, October 3, 1913; “Film Aide Saves Actress from Mad Ape’s Attack,” Los Angeles Times, July 7, 1936; “Monkey Caged after Biting Second Person,” Los Angeles Times, January 8, 1939.

just a few months before forging an alliance with Hitler: “Mussolini Attacked by Mad Ox: African Fete Throng in Panic as Horns Barely Miss Premier,” New York Times, March 15, 1937.

many of the most enduring stories concern elephants: “Bad Elephants,” Los Angeles Times, January 16, 1887; “Mad Elephants: A Showman’s Recollections of Keepers Killed and Destruction Done by Them. Peculiarities of the Beasts,” Boston Daily Globe, November 20, 1881; “Mad Elephants: The Havoc the Great Beast Causes When He Rebels against Irksome Captivity,” New York Times, August 26, 1880; “Mad Elephants: Big Charley Killed His Keeper at Peru, Indiana.

the mad elephant genre, published in the New York Times in 1880: “Mad Elephants: The Havoc the Great Beast Causes When He Rebels against Irksome Captivity.”

Accounts of elephants going mad: See, for example, “An Elephant Ran Amok During the Shooting of a Film,” Orlando (FL) Sentinel, March 7, 1988; “Woman Trying to Ride an Elephant Is Killed,” New York Times, July 7, 1985; “Elephant Storms Out of Circus in Queens,” New York Times, July 11, 1995; Phil Maggitti, “Tyke the Elephant,” Animals’ Agenda 14, no. 5 (1994): 34; Karl E. Kristofferson, “Elephant on the Rampage!,” Reader’s Digest 142, no. 854 (1993): 42; “African Elephant Kills Circus Trainer,” New York Times, August 22, 1994.

Captive elephants have been known to suddenly explode into violence: While it would end up being applied predominantly to animals and human children, in the seventeenth century the phrase running amok concerned Malaysians and opium. Traveling Portuguese described frenzied Malaysians as “Amucos,” and many reports associated the state with being high. In his 1833 Naval History of England R. Southey wrote about the “pitch of fury which the Malays excite in themselves by a deleterious drug, before they run amuck” (perhaps ignoring the more obvious role of colonization and oppression in any frenzied behavior among Malaysians). Twenty-five years later it was being applied to animals. See “amok, n. and adv.,” Oxford English Dictionary Online, June 2011, http://www.oed.com/view/Entry/6512?redirectedFrom=amok. Other elephants targeted no individual but rampaged around until they were caught and hanged, electrocuted, or otherwise punished. In 1902 a “huge mad elephant” named Mandarin was strangled with a chain in New York after running amok with the Barnum and Bailey Circus. In 1920 a story of the dramatic escape by a British soldier from the tusks “of a mad elephant” made the American papers. “Bad Elephants,” Los Angeles Times, January 16, 1887; “Mad Elephant: Big Charley Killed His Keeper at Peru, Indiana”; “Death of Mandarin”; “British Soldier’s Miraculous Escape from Death on Tusks of a Mad Elephant”; “Mad Elephant Rips Chains and Walls.”

Chunee, a once docile Asian elephant: Ritvo, Animal Estate, 225–27.

Gunda too was once an approachable star elephant: “Death of Gunda.”

Debates over what to do with him captivated New Yorkers: Ibid.; William Bridges, Gathering of Animals: An Unconventional History of the New York Zoological Society (New York: Harper & Row, 1974), 234–42; “Bullet Ends Gunda, Bronx Zoo Elephant.”

Forepaugh’s shows included: Advertisement for Adam Forepaugh’s Circus in Athletic Park, Washington, D.C., National Republican, April 11, 1885, http://chroniclingamerica.loc.gov/lccn/sn86053573/1885–04–11/ed-1/seq-6/ (accessed May 1, 2012).

Tip was “docile as a lamb”: “An Elephant for New York: Adam Forepaugh Presents the City with His $8,000 Tip,” New York Times, January 1, 1889; “Tip Is Royally Received: Forepaugh’s Gift Elephant Arrived Yesterday. Met at the Ferry and Escorted through the Streets by Thousands of Admirers,” New York Times, January 2, 1889.

For his first few years inside the Central Park elephant house: “Tip’s Life in the Balance: The Murderous Elephant’s Fate to Be Decided Tomorrow,” New York Times, May 8, 1894; Wyndham Martyn, “Bill Snyder, Elephant Man,” Pearson’s Magazine 35 (1916): 180–85; John W. Smith, “Central Park Animals as Their Keeper Knows Them,” Outing: Sport, Adventure, Travel, Fiction 42 (1903): 248–54.

“must reform or die”: “Tip Must Reform or Die: Central Park’s Big Elephant on Trial for His Life,” New York Times, May 3, 1894.

One morning, as the keeper went to feed Tip his breakfast: Ibid.; Smith, “Central Park Animals as Their Keeper Knows Them,” 252–54.

The elephant waited three years to try to hurt Snyder again: “Tip Must Reform or Die”; “Tip’s Life in the Balance”; Martyn, “Bill Snyder,” 180–85.

Daily newspaper articles covered his plight: Charles David, a man who had worked for Forepaugh and known Tip for years, put it this way: “I think Snyder doesn’t exercise Tip enough. . . . In circuses, when an elephant gets unruly, they punish him . . . or they walk him from one town to another, twenty miles or so. That takes the ugliness out of him. If Snyder cannot subdue Tip, then they ought to get another keeper.” Apparently David was ignored.“Tip Must Reform or Die”; “Tip’s Life in the Balance”; “Tip’s Life May Be Sacred: Mr. Davis Says the City Agreed He Should Not Be Killed,” New York Times, May 7, 1894.

He also may have been going through musth: An elegant account of another elephant in musth is the centerpiece of George Orwell’s 1936 essay “Shooting an Elephant.” As a colonial officer in Burma, he was pressured to shoot a “mad elephant”: “I watched him beating his bunch of grass against his knees, with that preoccupied grandmotherly air that elephants have. It seemed to me that it would be murder to shoot him.” George Orwell, Shooting an Elephant, and Other Essays (New York: Harcourt, Brace, 1950); Preecha Phuangkum, Richard C. Lair, and Taweepoke Angkawanith, Elephant Care Manual for Mahouts and Camp Managers (Bangkok: FAO Regional Office for Asia and the Pacific, 2005), 52–54.

a new wave of animal advocates: See Anita Guerrini, Experimenting with Humans and Animals: From Galen to Animal Rights (Baltimore: Johns Hopkins University Press, 2003); Carol Lansbury, The Old Brown Dog: Women, Workers, and Vivisection in Edwardian England (Madison: University of Wisconsin Press, 1985); Susan J. Pearson, The Rights of the Defenseless: Protecting Animals and Children in Gilded Age America (Chicago: University of Chicago Press, 2011); Keith Thomas, Man and the Natural World: A History of the Modern Sensibility (New York: Pantheon Books, 1983).

the Central Park commissioners unanimously decided: I was not able to verify whether Tip actually killed anyone, and I doubt the Parks Commission was able to either. “Tip Tried and Convicted; Park Commissioners Sentence the Elephant to Death,” New York Times, May 10, 1894; “Tip Swallowed the Dose; But Ate His Hay with Accustomed Regularity in the Afternoon. Tried to Poison an Elephant. It Was Unsuccessful at Barnum & Bailey’s Winter Quarters Yesterday. If It Fails To-day the Animal Will Be Shot,” New York Times, March 16, 1894; “Tip to Die by Poison To-Day; Hydrocyanic Acid Capsules in a Carrot at 6 A.M.,” New York Times, May 11, 1894.

The park flooded with visitors: “Big Elephant Tip Dead: Killed with Poison after Long Hours of Suffering,” New York Times, May 12, 1894.

The term nostalgia could be used interchangeably with homesickness: Nostalgia was first diagnosed in 1678 by a Swiss doctor, Johannes Hofer, and was considered an “affliction of the imagination” caused by the desire to go back to one’s native land. Soldiers, students, prisoners, exiles, or anyone barred from returning to their home could contract the disease, according to another Swiss doctor in 1720. The disease was characterized by the single-minded obsession with return. Nostalgia wasn’t “demedicalized” until the turn of the twentieth century, when it lost its “bodily connotations and became even more linked with time.” Jennifer K. Ladino, Reclaiming Nostalgia: Longing for Nature in American Literature (Charlottesville: University of Virginia Press, 2012), 6–7.

Almost sixty years later my email inbox is full of friendships like this. Not a week goes by that someone doesn’t forward me photos of a dog and an orangutan splashing around in a plastic tub, or baby pigs cuddling up to a tiger, or a snake and a rabbit curled around each other in some sort of multispecies friendship ring. A number of these little photo essays, as anthropomorphic, cutesy, and staged as many of them are, also discuss loneliness and depression as reasons for the surprising relationships.

Monarch’s mounted body served as one of the models: Tracy I. Storer and Lloyd P. Tevis, California Grizzly (Berkeley: University of California Press, 1996), 276.

few people know the bear was an actual: “Grizzly Comes as Mate to Monarch: Young Silver Tip Shipped from Idaho Arrives Safely and Is Now in Park Bear Pit,” San Francisco Chronicle, February 10, 1903.

Monarch was an icon of a recently neutered wilderness: There has been much good scholarship on the shifting attitudes toward Western wilderness over the course of the late nineteenth and early twentieth centuries, as American Indians were removed from the nation’s new national park system, grizzly and wolf populations were decimated, and the federal government established monitoring agencies (U.S. Fish and Wildlife Service, the National Park Service, and more) to oversee the newly consolidated governmental land holdings—regulating who did or did not have access to resource-rich lands and how this both reflected and helped shape American conceptions of wilderness and the American frontier.

A few weeks became months: How verifiable those details are is a matter of interpretation, since no other account exists. While not everything that happened in the tale of Monarch may have happened to Monarch the individual, it probably happened at some point with some bear of Kelly’s. Ernest Thompson Seton questioned Kelly in 1889 about the authenticity of the Monarch account published in the Examiner. Seton wrote, “It is safe to say that many adventures ascribed to this bear belonged to various and different bears.” Storer and Tevis, California Grizzly, 250; Allen Kelly, Bears I Have Met—and Others (Philadelphia: Drexel Biddle, 1903), http://www.gutenberg.org/files/15276/15276-h/15276-h.htm.

The country’s wildlands and wildlife: Ibid., 76.

Places like Yosemite and Yellowstone could now be seen as antidotes: The historian William Cronon has argued that when Turner announced the closing of the frontier, Americans who felt a sense of loss were already looking backward, mourning an older, simpler, and more peaceable country. The problem is that such a country never actually existed: the extirpation of native peoples, the decimation of buffalo, wolf, and grizzly populations, and the drastic ecological damage brought on by mining and massive deforestation were the kinds of violence that did not figure into romantic ideas of the nation’s wilderness ideals. Cronon, “The Trouble with Wilderness.”

Efforts to protect and celebrate these places: Ibid., 76, 78.

the new female “typified the saying”: “Grizzly Comes as Mate to Monarch.”

“The poor little cub died”: “Grizzly Bear Cub Is Dead,” San Francisco Chronicle, January 18, 1904. A subsequent article claimed the cub died of a head injury after Montana dropped it the day it was born. A second serving of disdain for Montana’s mothering skills was served up for San Franciscans: “Monarch and his diffident spouse Montana, the two grizzlies who live in an iron cage near the buffalo paddock, held an informal reception yesterday for many visitors who called to offer their sympathy for the untimely death of their offspring. Considering that Mrs. Monarch partially ate one of her twins and ignored the other almost entirely, the condolences of her visitors seemed ill-placed.” “Great Crowd Visits Park: Police Estimate Attendance of Fully Forty Thousand People at the Recreation Grounds,” San Francisco Chronicle, January 25, 1904.

Four years later Monarch was confirmed: Board of Parks Commissioners, Annual Report of the Board of Parks Commissioners 1910, June 30, 1910, 40–43.

Perry’s very first patient: Over the course of three years, Perry was able to help Tina regain control over her stress response and make decisions after thinking them through instead of blindly reacting.

Studies using mice as stand-ins: The fact that humans tend to pluck themselves and mice tend to pluck one another hasn’t stopped the use of mouse experimental models. Since both the barber mouse and her client engage in the process by choice, even though it must be at least a little painful, researchers have tended to assume, for better or for worse, that the behavior in people is simply spread between two individuals in the mice.

According to the study’s lead researcher: Susanne Antonetta, “Language Garden,” Orion, April 2005, http://www.orionmagazine.org/index.php/articles/article/152/ (accessed August 10, 2011).

Aristotle told the story: Edmund Ramsden and Duncan Wilson, “The Nature of Suicide: Science and the Self-Destructive Animal,” Endeavor 34, no. 1 (2010): 21.

Since its first documentation: “Suicide,” Oxford English Dictionary Online, http://www.oed.com/view/Entry/193691?rskey=6JPREr&result=1. Before the eighteenth century, someone could be a “self-destroyer,” “self-killer” “self-murderer,” or “self-slayer,” but not a suicide victim.

The DSM-V does not include suicide: Nor does it mention people who choose to end their own lives because they have terminal diseases. “Proposed Revision,” DSM5.org, http://www.dsm5.org/ProposedRevision/Pages/proposedrevision.aspx?rid=584# (accessed April 1, 2013). See also American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders-IV (Washington, DC: American Psychiatric Association, 1994) for suicidal ideation and attempts but no suicidal disorder.

The traits and behaviors in lab animals: Ibid.

According to the American Association of Suicidology: A suicide note demonstrates that the person intended to kill themselves but the notes often stop short of explaining their motivations. There are clear-eyed exceptions, of course, full of insight or directions on how the person wants to be disposed of, or what they want in a memorial service, but more often than not the notes simply illustrate the range of emotions that the people writing them were feeling at the time.

Lindsay’s work reflects a larger shift: Ramsden and Wilson, “The Nature of Suicide.”

“sufficiently barbarous . . . to induce”: C. Lloyd Morgan, “Suicide of Scorpions,” Nature 27 (1883): 313–14. Four years later another member of the Royal Society published a paper, “The Reputed Suicide of Scorpions,” arguing that insects were immune to their own venom, and the question of scorpion suicide seemed to be settled.

he published Mental Evolution in Animals: George John Romanes, Mental Evolution in Animals (New York: D. Appleton, 1884).

Romanes, like Lindsay and Darwin, believed that insanity: Ibid., 148–74; Lorraine Daston has argued that for Romanes, anthropomorphism was a virtue and a necessity since it demonstrated a direct evolutionary relationship between humans and other animals. To Morgan, though, it was faulty human projection. Lorraine Daston, “Intelligences: Angelic, Animal, Human,” in Thinking with Animals: New Perspectives on Anthropomorphism, ed. Lorraine Daston and Gregg Mitman (New York: Columbia University Press, 2005), 37–58.

Meanwhile, the idea of suicide: Ramsden and Wilson, “The Nature of Suicide,” 24.

people’s motivations to do themselves in could have “secret causes”: Enrico Morselli, Suicide: An Essay on Comparative Moral Statistics (London: Kegan Paul, 1881), 8.

Durkheim published his landmark book: In the introduction he made a point of explaining why he would not be including nonhuman animals: “Our knowledge of animal intelligence does not really allow us to attribute to them an understanding anticipatory of their death nor, especially, of the means to accomplish it. . . . All cases cited at all authentically which might appear true suicides may be quite differently explained. If the irritated scorpion pierces itself with its sting (which is not at all certain), it is probably from an automatic, unreflecting reaction. The motive energy aroused by his irritation is discharged by chance and at random; the creature happens to become its victim, though it cannot be said to have had a preconception of the result of its action. On the other hand, if some dogs refuse to take food on losing their masters, it is because the sadness into which they are thrown has automatically caused lack of hunger; death has resulted, but without having been foreseen. Neither fasting in this case nor the wound in the other have been used as means to a known effect.” Emile Durkheim, Suicide: A Study in Sociology (Glencoe, IL: Free Press, 1951), 44–45.

Reports of dolphin and whale mass suicides: See, for example, “Mass Suicide: Whale Beachings Puzzle to Experts,” Observer Reporter, July 27, 1976. One reason for the increasing numbers of reported strandings may have been, as Norman et al. suggest, the growing establishment of formal stranding responder networks between 1930 and 2002. Spikes of reported strandings also happen to occur during summer months, when more human observers are on beaches and along waterways, where they may witness stranded animals. S. A. Norman, et al., “Cetacean Strandings in Oregon and Washington between 1930 and 2002,” Journal of Cetacean Research and Management 6 (2004): 87–99.

The zoo’s public affairs manager: Friend, “It’s a Jungle in Here.” A related sentiment is touched upon in Emily Martin’s Bipolar Expeditions, 225, in which she suggests that bipolarity was seen, at least for a time and by certain New Yorkers, as a New York City phenomenon—the frenetic pace of the city possibly attracting the already bipolar or inciting bipolarity in those prone to it, influenced the types of disorders New Yorkers recognized in their zoo animals.

Dodman prescribes a wide variety of psychopharmaceuticals: Buspar, another drug he uses, was first tested in the late 1980s in dogs with storm phobias. Dogs given the drug acted calmer when the thunder was far away but still got extremely anxious when it passed overhead. He has also used it for fear aggression and social anxiety and says it’s really effective for treating dogs who like to pee in the house and for canine car sickness. Dodman, The Well-Adjusted Dog, 233–34.

Dodman shared his ideas for the first time: James Vlahos, “Pill-Popping Pets,” New York Times Magazine, July 13, 2008.

Mass killings at the hands of humans: The near extinction of the population affected not only their behavior (how far they had to travel to find mates, for example, and narrowing their choices) but also their biology (constraining the genetic diversity of the population). How it affected them culturally is a mystery.

Adolf Hitler loved his German Shepherd: One of his last acts before killing himself was poisoning her.
