Most of the earlier authors regarded it as a protein or a product derived therefrom. Recently some American authors, Warden, Connell, and Holly, have emphatically declared the toxin to be a "colloidal" mixture of fats and protein. As to the formation of t...

Toxin of sufficient strength to kill a 400-gramme guinea-pig in three days and a half in a dose of 0.cubic centimetre developed in suitable bouillon, contained in ordinary Erlenmeyer flasks, within a period of twenty-four hours. In such boullon the toxin reached its greatest strength in from four to seven days (0.005 cubic centimetre killing a 500-gramme guinea-pig in three days). This period o...
