* Engels’s Addendum to Capital Volume 3 was the last piece he wrote, apart from a few final letters. It dates from May 1895, only two months before his death. The Addendum is compiled from two articles which Engels planned to write for Neue Zeit, though only the first of these, ‘Law of Value and Rate of Profit’, was completed. For the second article, ‘The Stock Exchange’, there is simply a brief outline.
