in such cases. It must not be supposed, however, that exactly 

 similar results would always be obtained by analyses of fluids 

 from the same organs. The composition of pus serum is 

 somewhat similar; it contains, however, more products of 

 protein disintegration.

Amniotic Fluid. This may be considered as a kind of 

 transudate. A number of analyses have been made which 

 show about 98.5 per cent of water, i per cent of salts and 0.5 

 per cent of organic solids, largely proteins. 



THE LYMPH CELLS. 



These large cells or leucocytes have already been referred 

 to as formed in the lymph glands. They are also formed in 

 large numbers in the spleen and the thymus gland. From 

 whatever source produced they are supposed to have the same 

 general composition and chemical function. The following 

 analysis by Lilienfeld gives an idea of their general composi- 

 tion. The dry substance of the cells amounted to 114.9 parts 

 per 1000 and was made up of the following constituents, the
