V. Composition of the Crassamentum. 



To determine the composition of the crassamentum, I made 

 choice of the crassamentum from No. 1 (p. 349), because the 

 serum of that specimen was quite free from colouring matter. 

 One hundred parts of it were dried in a temperature of about 

 200° till they ceased to lose weight : the residue weighed 35-43. 

 — Hence this crassamentum was composed of 



Water 64-57 



Solid matter 35-43 



100-00
