(" Physiological Aspects of the Liquor Problem," by permission of Dr. Hodge and of Houghton, Mifflin & Co.) facts were learned as to the general effect of alcohol on physiological processes. Early in his observations it became evident to Professor Hodge that the dogs that were receiving the alcohol were far less playful than were those that had no alcohol in their food. To measure the comparative activity of the different animals, he attached to the collar of each dog a Waterbury watch adjusted in such a way that it would tick.
