1 8 2 L YMPH AND ALLIED FL UIDS.

 case of fistula of the thoracic duct in man : l

They obtained only O'l per cent, of fibrin (as compared with 0*4 per 

 cent, in blood plasma). This is perhaps the reason why the intravenous 

 injection of peptone in small amount or at a slow rate may, as noticed 

 by L. E. Shore, 3 prevent the clotting of the lymph but not that of the 

 blood. The experiments of Spiro and Ellinger 4 seem, however, to 

 indicate that, under the influence of peptone, an anti-coagulating 

 substance is formed in lymph, and from this passes into the blood. 

 The other proteids are also present in much less amount, but the relative 

 proportion of albumin to globulin is almost exactly maintained. As 

 already stated (p. 162), the present proteid quotient is fairly constant in 

 the same individual, both for blood serum, lymph serum, and serous 

 effusions. 5 Lymph generally contains more urea than does the blood of 

 the same individual. Thus in a dog Wurtz found 



In the blood, 0-009 parts per cent, of urea.

The amount of sugar in lymph is about the same as in blood plasma, 

 although, if dextrose be injected into the blood vessels, it soon appears in 

 greater proportion in the lymph than in the blood. 6 Lymph contains 

 a distinct amount of glycogen, but this substance is wholly contained in 

 the corpuscles, and none exists in the plasma. 7 



The aqueous humour is a form of lymph, and contains the same pro- 

 teid substances as lymph, namely, fibrinogen, serum globulin, serum 

 albumin, and similar extractives and salts. 8 It contains no corpuscles,
