the same concentrations in the serum and in the edema fluid. The 

 freezing point is also the same in both fluids, while the specific con- 

 ductivity is constantly higher in the edema fluid. 



3. The above mentioned variations between the edema fluid and 

 the serum appear to be related to the difference in the concentration 

 of protein in the two solutions. 



4. The relationships between blood serum and edema fluid seem to 

 result from a simple membrane equilibrium, influenced in part by the 

 proteins present.
