In Diarrhœa, five grains of chalk, two grains of cayenne, and five grains of powdered rhubarb may be given, and if the discharge is not speedily checked, a grain of opium and the same quantity of ipecacuanha may be administered every four or six hours. DISEASES OF THE EGG ORGANS.--The most important disease of these organs is inflammation of the egg passage, shewn by the laying of soft or imperfect eggs; this complaint is readily remedied by giving one grain of calomel and one-twelfth of a grain of tartar emetic, made into a pill with meal; sometimes soft eggs arise from a deficiency of lime, in which case, a little old mortar rubbish remedies the defect. The calomel and tartar emetic, which I first recommended for this disease in the _Cottage Gardener_, has been frequently given in other diseases, such as inflammation of the stomach, &c., and I need scarcely say with the effect of aggravating the evil very materially; there is no universal poultry medicine. Disease of the ovary, or organ in which the yolks are formed, is not unfrequent, when the comb and wattles become like those of the cock, and the hen crows frequently; such birds are generally but erroneously termed hen-cocks, they must not be confounded with the hen-feathered cocks spoken of in the article on Hamburghs. DISEASES OF THE LIMBS.--Cramp in young chicken from exposure to cold and damp is very fatal to early hatches, it can be prevented only by warmth and dryness. Leg weakness, which is most frequent in rapidly growing chicken and young birds, particularly Cochins, arises from a disproportion between the weight and strength of the animal, the bird in consequence, sinks down upon its hocks; I have found four or five grains of citrate of iron given daily in meal successful in every case in which I have employed it. Inflammation of the feet, closely resembling gout, I have seen in many cases, particularly in Cochins; the feet become very hot and swell. One grain of calomel at night and three drops of colchicum wine twice a day, I have found afford considerable relief. The bumble foot of Dorkings, is a swelling occurring in the ball of the foot, not attended with heat, but followed by ulceration and a diseased growth. I have found that it may, to a great degree, be prevented by having the perches broad and low, not above four feet in height, as the disease is evidently set up in many cases, and increased in all, by the violence with which the heavy birds descend to the ground; from the low vitality of the parts affected, I have found that no treatment is attended with any beneficial results.
