The following table exhibits the constituents of human blood 

 as determined by Mr Richardson in my laboratory. His colour- 

 ing matter was obviously the globules of the blood, consisting of 

 fibrin, hematosin, and albumen, in the proportions just stated : 



Specific gravity of the blood, 1-053. 

 Water, .... 785-890 



Fibrin, . . . 2' 120 



Colouring matter, . . . 134-780 



Albumen, . . . 63-008 



Cholesterin and serolin, . . 1-357 



Oily fatty matter, . . 0-808

The following curious table, drawn up by M. Denis from his 

 own experiments, and exhibiting the constitution of blood at dif- 

 ferent ages, deserves to be inserted.*
