 this book would be a great acquisition to British physiologists. 



The following are the ultimate results of the analyses given by 

 Berzelius in his views of the chemical properties of the animal 

 fluids. 



1. Blood consists of crassamentum and serum. The crassamen- 

 tum is composed oi fibrin and colouring matter. This colouring 

 matter is of an animal nature, and nearly similar in its properties 

 to fibrin : 100 parts of serum were found to contain the following 

 substances : — 



Water 9O5'0O 



Albumen 79-99 



Lactate of soda and extractive .") ^^^ 



Muriates of soda and potash . . J ^

Blood also contains iron ; but it does not owe its colour to sub- 

 phosphate of iron. The phosphates found in the ashes of the blood 

 are formed during the incineration. 



2. Lactic acid is not, as the French chemists have endeavoured 

 to prove, a modification of acetic acid, but a peculiar acid, pos- 

 sessed of very different properties from every other. Blood contains 

 no gelatine. Albumen approaches in its properties to fibrin. 



3. The secretions contain each a peculiar substance, to which it 

 owes its properties ; if this be removed the other substances are the 

 same in all. 



4. Bile contains no resin, but a peculiar bitter substance, soluble 

 in water and alcohol, called by Berzelius biliary matter; 1000 parts 

 of bile yield
