Effects of anemia (aortic obstruction) on activity of enervated intestine. We are therefore inclined to ascribe the post-mortem activity of the intestines in the rabbit, not to the anemia or asphyxia of the intestinal wall, but to the paralysis of the nerve-centres, and the con- sequent cutting off of the intestines from all inhibitory impulses. It is quite possible, as Engelmann suggests, that when the vagi are intact we have superadded a distinct motor effect due to central stimulation of these nerves resulting from the asphyxia. In a rabbit, with all the nerve-connections of the intestine intact, cutting out a loop of intestine increases for a time its activity, and in such a loop it may for a time be possible to elicit local reflexes which could not be obtained with the intestine in stv. III. THE SMALL INTESTINE OF THE CAT. The similarity between the intestine and alimentary habits of the dog and cat led us to anticipate that we should find a very exact correspondence between the properties of the intestines of the two animals. We were much surprised to find in the majority of our ex pe-
