Excerpt from A Report on the Physiological Action of Chloroform: With a Criticism of the Second Hyderabad Chloroform CommissionIn our investigations we have used rabbits and dogs. Most of the experiments were made on rabbits, because we desired to -register the movements of respiration as well as the condi tion of the blood pressure, and, in our opinion, no better method exists for the registration of the movements of respi ration, both as regards rate and nature of muscular contrae tion, than that introduced by Head, 8 a method which is only applicable to the rabbit, and consists of the direct registration of the contractions of an isolated strip of the diaphragm muscle itself. In all cases a dose of chloral hydrate was given to the rabbit before the experiment commenced, and, in the case of dogs, they were always under the in¿uence of acetate of morphine before the chloroform was administered.The blood pressure, taken either from the carotid or femoral artery, was measured by a mercury manometer, recording in the ordinary way on Ludwig's kymograph.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
