starch. This protoplasm consists of inorganic and of organic 
matter, under which lattter term the albuminous materials and 
their products of modification or decomposition play an important 
part. The air-dried substance of the Plasmodium septicum con-

Besides there are present hydro-carbons, albuminous matter, 
and other nitrogenous bodies, which are more products of decom- 
position of albumen. 
“There are certainly disastase, fat emulsion-making ferments 
contained in it, besides plastin and albumen substance like fibrin, 
Myosin, Quenin, Sarkin, Xanthin, Carbonate of Ammonia, Butyric 
acid, and Coneisinic acid.’ 
All these substances are composed of carbon, hydrogen, oxy- 
gen and nitrogen, with small quantities of sulphur and phos- 
phorus, etc.
