Experimental results are presented which show that:
The serum proteins of individual rabbits vary through a wide range and that the variation is even greater between different rabbits.
Intravenous injections of large amounts of gelatin does not produce any marked change in the ratio of the globulins to the total proteins.
The gelatin begins to disappear from the blood immediately after injection and continues to do so at a fairly constant rate, being completely eliminated at some time between six and twenty-four hours.
The injection of gelatin causes tissue fluids to be drawn into the blood stream, resulting in hydremic plethora.
