THE LYMPH. 361 



which has escaped decomposition in the intestinal canal and has 

 been resorbed. They subsequently enter the blood-current, carried 

 by the leucocytes, and are again eliminated in the bile. 



Traces of urea, uric acid, lecithin, xanthin, kreatin, and lactic 

 acid are commonly found. 



Of ferments, a diastatic ferment and a glncolytic ferment have 

 been described. 



The gases of the lymph differ from those of the blood in the 

 presence of larger amounts of carbon dioxide 35 to 45 per cent. 

 as compared with arterial blood, and smaller amounts than are 

 found in venous blood. The tension of the carbon dioxide, as 

 compared with venous blood, is lower, which suggests that a por- 

 tion of the gas enters the blood from the lymph through a reverse 

 secretory activity of the capillary endothelium. Oxygen is present 

 only in traces, while the amount of nitrogen is the same in both, viz., 

 1.6 per cent. 



For purposes of comparison and reference, a few analyses of some 

 of the more important normal and pathological varieties of lymph 

 are appended. Some of these will be considered in greater detail 

 in subsequent chapters.
