Here is an analysis comparing lymph with blood 



It can be easily understood that the chemical composition 

 of the lymph will depend upon the nature of the food sup- 

 plied, and also the sources from which the lymph is 

 obtained. The following table illustrates the differences in 

 the lymph of the horse, depending on its source : 



The Quantity of Lymph in the body is very difficult to 

 arrive at, and varies considerably; 13] lbs. of lymph have 

 been collected in two hours from a lymphatic vessel in the 

 neck of a horse (M. Smith). Landois mentions that 2.1 ozs. 

 to 3£ ozs. have been collected from the same place in l\ to 

 2 hours. Colin obtained from a lymphatic in the neck of 

 horses a quantity which varied between 1 to 4 lbs. in 

 24 hours; the mean amount was 2 lbs. G ozs. for the same 

 period, but he notes that the variations are wry wide, and 

 that herbivora secrete more than carnivora, and young 

 animals more than adults. The amount of material col-
