xviu SYNOPSIS 



produce skin lesion, (c) growth in milk — fermentation by B. coli, rash in 

 scarlet fever, {d) effect of substances added to media and of drugs in disease 

 • — sod. benzoate and B. coli — sod. salicylate and acute rheumatism. 

 (14) Different symptoms due to different enzymes? — analogy with sugar 

 ferments of bacteria — complexity of action — association with particular 

 vegetable and bacterial cells — ^possibility of complete dissociation of patho- 

 genic enzymes? (15) Two results obtainable — organisms deprived of patho- 

 genic functions {B. typhosus) — functions maintained in absence of organism, 

 e.g. filter passers. (16) No enzyme isolated which forms toxins outside the 

 body — true also of other recognised ferments — artificial media differ from 

 vital fluids. (17) The enzyme theory and transmutation — suggests transfer 

 of function possible — certain conditions essential. Analogy of ships at sea.
