THE BLOOD VOLUME OF NORMAL DOGS

Abstract
Plasma, cell and total blood vol. were detd. by the dye method of Gregeisen, Gibson and Stead in 50 normal mongrel dogs. With increasing body wt. there is an increase in absolute plasma, cell and total blood vol., and an increase in unit plasma, cell and total blood vol. expressed in cc. per kgm. of body wt. Unit cell vol. tends to increase more rapidly than unit plasma vol. With increase in total blood vol. there is an increase in hematocrit and hemoglobin values, and a slowing of blood velocity rate.
