Abstract
Using the micro-quinhydrone method of Cullen a comparison was made in each of a series of amytalized animals of the pH of blood from the coronary vein with that of blood taken from other venous sources. The pH of the coronary venous blood was not significantly different from that of blood from the femoral vein, the portal vein, the inferior vena cava or the right auricle. The oxygenated blood of the left auricle, however, was slightly more alkaline than the other samples. In an additional series of animals there was no material difference between the lactic acid content of the coronary and that of the caval blood.
