The relationship between tissue fluid and lymph

Protein concentration in the fluid aspirated from subcutaneously implanted capsules is higher both in dogs and in rabbits than in the lymph collected from the same area. Besides the quantitative differences there are also qualitative differences in the composition of the two fluids. It is concluded, that the capsular fluid is not identical with normal tissue and that from its composition no informations can be gained about the origin of lymph or the mechanism of its formation.
