In the former case the capillary pressure may be high, but not so in the 

 latter case. To maintain the volume of the blood normal in both these 

 conditions, absorption must occur in the unaffected portions of the vascula 

 system, but this absorption is not so great as it would be if the excretion 

 of urine were not diminished. The dropsy of general venous stagnation 

 is essentially local in origin, and the locality increases in extent as the 

 disease advances. 



Experiments are now being undertaken to estimate the lymph flow in the 

 various pathological conditions considered above.
