 that the amount of sugar in the lymph is approxi- 

 mately the same as in the blood. It had been stated 

 by Bernard that the lymph of the intestinal tract (chyle) does not 

 take up sugar when animals are fed upon a starchy or saccharine diet, 

 and the statement is confirmed by v. Mehring. 



Urea Urea is a constant ingredient of the lymph and 



present in the chyle, as was first pointed out by Wurtz 3 . The amount 

 lymph. Q f ureaj }ik e that of sugar, appears to be the same 



in the lymph and blood. 



The following are the results obtained by Wurtz; although, 

 owing to the method employed, the amount of urea found was much 

 below the actual amount, the observations are doubtless comparable 

 with each other.

Other ex- 

 tractives 



According to Lehmann the chyle of the horse 

 tractives contains alkaline lactates, and according to Frerichs 



present in the and Staedeler, leucine and tyrosine are also present in 



lymph and lymph; no definite information on these subjects is yet

The Salts of the Lymph. 



Like the other constituents of the lymph, the sadts vary consider- 

 ably in proportion according as the fluid is more or less rich in water. 



The salts are relatively much more abundant than the organic 

 solids, so that we may say that in transuding through the walls of 

 the blood-vessels, the liquor sanguinis furnishes to the lymph a small 

 quantity of its fibrinogen, about one-half of its serum-albumin, and a 

 much larger proportion of its salts. 



The composition of the salts of the lymph and chyle appears to 

 be the same as that of the salts of the liquor sanguinis, in both cases 

 sodium chloride constituting the overwhelming constituent.
