and uric acid. There is also a protein allied to alkali-albumen, 

 combined with iron, as well as several pigments probably derived from 

 the haemoglobin of the red corpuscles destroyed by the cells of the 

 splenic pulp. The fact that, in cases where the spleen is pathologically r 

 enlarged as in leucocythaemia, the uric acid in the urine is largely ; 

 increased, points to a connection between the spleen and the formation 

 of uric acid in the body. The numerous extractives which are formed 

 probably owe their origin to the destructive changes effected on 

 the effete constituents of the blood by the agency of the splenic 

 pulp-cells.
