ctors, fibrinoplastin and fibrinogen, under the influence of a 
third body, fibrin ferment. A number of reasons led to the be- 
lief that one or more of the bodies necessary to the formation of 
fibrin was derived from disintegrated white blood corpuscles, 
Schmidt taught that fibrinoplastin and fibrin ferment owed their 
origin to the breaking down of white blood corpuscles or allied 
eres, while fibrinogen was present in normal circulating blood
