As regards curative treatment, the diseased animals should be grouped and isolated as far as possible, and should receive doses of the following vermifuge:— Powdered areca nut 2 ounces. Arsenic 30 grains. The above is sufficient for ten animals, and a dose should be given daily for a period of six days in a small quantity of bran. Treatment is completed by abundant nourishment, and by distributing about the pastures pieces of rock-salt suitably protected. Many other vermicides or vermifuges have been suggested, but are less easy to use. They comprise essence of turpentine, mixtures of oil with essence of turpentine and benzine, picrate of potash in doses of 7 to 20 grains per day, ethereal extract of male fern, etc. LUMBRICOSIS OF CALVES. Following the example of human medicine, we apply the term “lumbricosis” to a disease caused by ascarides in calves, although Neumann separates the ascarides of calves from the lumbricoid ascarides with which they are usually confused in current practice. =Causation.= The disease is exclusively due to infestation with embryos of the parasite, which in young calves afterwards develop in the first portions of the intestine and in the abomasum, interfering with secretion, and producing mechanical disturbance, colic, and digestive irregularity, eventually followed by marked loss of condition. Death may even follow, either from rupture of the pylorus or duodenum, or from secondary septicæmia of intestinal origin, due to the parasites burrowing into the mucous membrane and facilitating infection. In adults of all species lumbricosis is rare. It occurs principally in young animals from the time of weaning up to the age of eighteen months or two years. =The diagnosis= cannot usually be formed until the parasites are found in the fæces, but microscopic examination sometimes reveals the presence of the eggs, and thus excites suspicion. Provided the condition is diagnosed early, the =prognosis= is not grave; but when patients have become exhausted and anæmic they require a long time to recover, even when freed from parasites. =Treatment.= Guittard recommends empyreumatic oil as very efficacious, and gives it in doses of 2½ to 3 drachms diluted with ordinary oil, or emulsified with any kind of mucilage. Calomel gives good results, and maybe administered in doses of 15 to 60 grains, according to the animal’s age and size. Powdered areca nut would probably be easier to administer with the food. Oil of turpentine is given mixed with ordinary oil, but its action is less certain. STRONGYLOSIS OF THE ABOMASUM IN THE OX. Although well studied by Stadelmann and Ostertag in Germany, and by Stiles in America, this disease has not yet been regarded in France as giving rise to accidents.
