"I should deem it advisable," said he, "to administer a purgative; but of what would that consist? Calomel? Certainly not. I was surprised to hear one gentleman assert that he should administer it to the extent of from five to ten grains, and another to say that he should not hesitate to exhibit a scruple of calomel to a dog, and to all carnivorous animals. I should never think of exhibiting it as a cathartic. I should only administer it in small doses, and for the purpose of producing its specific effect on the liver, which is the peculiar property of this drug. Given in larger doses it would not be retained, and if it got into the intestines it would act as a powerful drastic purgative." [3] In our treatment of the horse we have got rid of a great proportion of the destructive urine-balls and drastic purgatives of the farrier. The cow is no longer drenched with half-a-dozen deleterious stimulants. A most desirable change has been effected in the medical treatment of these animals. Let us not, with regard to the dog, continue to pursue the destructive course of the keeper or the huntsman. The following case of enteritis, with rupture of the colon, may be useful: On March 15, 1840, I was requested to attend a large dog of the bull breed, three years old, who had not appeared to be well during the last four or five days. I had scarcely arrived ere I recognised it to be a case of enteritis. He had a dreadful shivering fit, to which succeeded heat of the skin and restlessness. The muzzle was dry and hot, as also was the tongue. The eyes were sunken and redder than usual; the breathing was accelerated, but not very laborious; the extremities were cold, while the surface of the body was hot and painful to the touch. The bowels were constipated, and had been so during the last week; some dung however was evacuated, but it was hard and dry, and in small quantities. The pulse was quick, but full; and there was a slight pain and considerable irritation in the rectum. I took from him [Symbol: ounce] x. of blood before the desired effect was produced, and then gave him tinct. opii gr. xiv., et spt. ether, nit. gutt. viij., cum ol. ricini [Symbol: ounce] iij., and an opiate enema to allay the irritation of the rectum. This was about 8 o'clock, A.M. 11 A.M.--The bowels have not been moved, and the pain is more intense; his countenance expresses great anxiety; he frequently lies on his stomach, and the pulse is small but quick. I gave him a little broth, and ordered the abdomen to be fomented with hot flannels. 2 P.M.--He has had distressing sickness, and is extremely anxious for water. I introduced my finger into the rectum, but could not discover any hardened fæces. Enemata, composed of mag. sulphas and warm water, were frequently thrown into the intestines; as soon as one came away another was thrown up.
