The pulse of the greater part of our domestic animals has been calculated by Mr. Vatel, in his excellent work on Veterinary Pathology, to be nearly as follows: In the horse, from 32 to 38 pulsations in a minute. " ox or cow, " 35 " 49 " " ass, " 48 " 54 " " sheep, " 70 " 79 " " goat, from 72 to 76 pulsations in a minute. " dog, " 90 " 100 " " cat, " 110 " 120 " " rabbit, . . 120 " " guinea-pig, . . 140 " " crow, . . 136 " " duck, . . 136 " " hen, . . 140 " " heron, . . 200 " The pulse of the dog may be easily ascertained by feeling at the heart or the inside of the knee, and it varies materially, according to the breed, as well as the size of the animal. This is very strikingly the case with some of the sporting dogs, with whom the force as well as the rapidity of the pulse vary materially according to the character and breed of the dog. There is, occasionally, in the dog as in the human being, an alteration of the quantity, as well as of the quality, of the blood. 'Anæmia' is the term used to designate a deficiency in quantity; 'plethora' is the opposite state of it. M. D'Arbor relates a very curious account of the former: Two dogs were sent into the hospital of the veterinary school at Lyons. They did not appear to suffer any considerable pain. Their skin and mucous membranes that were visible had a peculiar appearance. They had also comparatively little power over their limbs; so little, indeed, that they rested continually on one side, without the ability to shift their posture. When they were placed on their feet, their limbs gave way, and they fell the moment they were quitted. In despite of the care that was taken of them, they died on the second day.
