With this view he performed a series of experiments, the results of which were always identical. By means of an œsophagal tube, Dr. Gréhant injected into the stomach of a dog thirty grammes of alcohol every half hour until the animal died. At the post-mortem examination, he found that the blood of the animal contained a proportion of one part of absolute alcohol to 100 parts of blood.”--_Lancet_, Jan. 20th, 1883, p. 125.
