THE VAPOR PRESSURE OF DOG'S BLOOD AT BODY TEMPERATURE.
The vapor pressures of dog's blood and blood plasma were determined at 37.5 degrees by the dynamic method and the osmotic pressures calculated from the experimental data. The vapor pressures calculated from experimentally determined freezing point data agreed, within the experimental error, with the values obtained from direct measurement. The vapor pressure lowering produced by the colloid constituents of the blood was also determined and found to be minimal compared to that of the other constituents.
