"Horn ail," as it is improperly termed, we have said, may accompany common catarrh, also that of an epidemic form; the horns will feel unnatural if there be a determination of blood to the head: this might be easily equalized by stimulating the external surface and extremities, at the same time giving antispasmodic teas and regulating the diet. The horns will feel cold whenever there is an unnatural distribution of the blood, and this may arise from exposure, or suffering the animal to wallow in filth. The author has been consulted in many cases of "horn ail," in several of which there were slow fecal movements, or constipation; the conjunctiva of the eyes were injected with yellow fluid, and of course a deficiency of bile in the abomasum, or fourth stomach; thus plainly showing that the animals were laboring under derangement of the digestive organs. Our advice was, to endeavor to promote a healthy action through the whole system; to stimulate the digestive organs; to remove obstructions, both by injection, if necessary, and by the use of aperients; lastly, to invite action to the extremities, by stimulating liniments. Whenever these indications are fulfilled, "horn ail" soon disappears. ABORTION IN COWS. Cows are particularly liable to the accident of "slinking the calf." The common causes of abortion are, the respiration and ultimate absorption of emanations from putrid animal remains, over-feeding, derangement of the stomach, &c. The filthy, stagnant water they are often compelled to drink is likewise a serious cause, not only of abortion, but also of general derangement of the animal functions. Dr. White, V. S., tells us that "a farm in England had been given up three successive times in consequence of the loss the owners sustained by abortion in their cattle. At length the fourth proprietor, after suffering considerably in losses occasioned by abortion in his stock, suspected that the water of his ponds, which was extremely filthy, might be the cause of the mischief. He therefore dug three wells upon his farm, and, having fenced round the pond to prevent the cattle from drinking there, caused them to be supplied with the well water, in stone troughs erected for the purpose; and from this moment the evil was remedied, and the quality of the butter and cheese made on his farm was greatly improved. In order to show," says the same author, "that the accident of abortion may arise from a vitiated state of the digestive organs, I will here notice a few circumstances tending to corroborate this opinion. In 1782, all the cows of the farmer D'Euruse, in Picardy, miscarried. The period at which they warped was about the fourth or fifth month. The accident was attributed to the excessive heat of the preceding summer; but, as the water they were in the habit of drinking was extremely bad, and they had been kept on oat, wheat, and rye straw, it appears to me more probable, that the
