In addition to these causes it has been suggested that ferments derived from the body cells may, under certain conditions, produce similar effects as in the case of anemic infarcts of the spleen and kidney.

It seemed probable that additional information could be gained of the factors underlying coagulation necrosis by studying the factors underlying the coagulation of culture media, containing blood serum, through bacterial agencies, as well as by experiments upon animals.
