third at 70°. The three glasses were brought into a room, the 
temperature of which varied from 40° to 50°. At the end of 
nineteen hours, the serum was found in the following quail- 
tities.

The blood did not flow so freely into the glass at the highest 
temperature, as into the other two.

From these experiments, it appears that the serum separates 
in larger quantity, when the blood is received into a vessel at 
the temperature of 70 degrees, than at 50° or 32 0 : this, how-
