They obtained only 01 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-coagulatmg 
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 m 
the same individual, both for blood serum, lymph serum, and serous 
effusions. 5 Lymph generally contains more urea than does the blood ol 
the same individual." Thus in a dog Wurtz found-

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.* 3 Lymph contains 
a distinct amount of glycogen, but this substance is wholly contained 111 
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 110 corpuscles,
