In Cochins which have been highly fed, particularly if peas and greaves have formed part of their food, a somewhat similar disease is often seen; and, as it commences with whiteness of the comb, it is frequently termed “white comb.” The treatment in severe cases is similar to that previously described; but mild attacks are said to yield to the application of turmeric mixed with cocoa-nut oil in the proportion of one part of the former to eight of the latter. Moulting, being a natural action, cannot be regarded as a disease, but it frequently is much delayed, and the birds evidently suffer in such cases; it is therefore desirable, when fowls are not moulting favourably, to treat them as invalids, giving them food which is more nourishing than usual, such as a little chopped meat, either raw or cooked, keeping them in a warm and sheltered habitation, &c. Lice often infest fowls to an extreme degree, and cause a great amount of irritation; this inconvenience may be prevented by giving them dry ashes to scuffle in, and keeping the houses clean and well lime-washed. When they are very abundant, flour of brimstone dusted under the feathers will be found a certain remedy; it is conveniently used if tied up in a piece of coarse muslin, or powdered from a flour dredger, or if more convenient, a pound or two may be added to the dust bath. DISEASES OF THE LUNGS AND AIR PASSAGES.--Roup is the most serious disease occurring in the poultry yard, not only on account of its affecting large numbers at one time, but also from the fact that it is not easily subdued by medical treatment; great confusion and difference of opinion have occurred from several distinct diseases having been confounded under this name. True roup commences with a sticky discharge from the nostrils, at first clear, but afterwards thick and of a very peculiar and offensive smell, the nostrils become partially or entirely closed, and there is consequently some slight difficulty of breathing, and a distention of the loose skin of the under jaw may be noticed; froth frequently appears at the inner corner of the eye, the lids swell, and in severe cases the sides of the face swell greatly, the fowl becoming blind; from the discharge being wiped on the feathers of the side and under the wing, they become matted together; and in addition to these symptoms there is extreme thirst. Roup is essentially a disease of the membrane lining the nose, similar in this respect to glanders in horses; I believe it to be highly contagious, and unless a roupy fowl is very valuable would recommend its being at once killed. I think the disease is often communicated by the discharge from the nostrils running into the water out of which the fowls drink. As to treatment, a roupy fowl should at once be removed from the yard, placed in a warm dry room, the nostrils and eyes sponged with warm water, and a solution of ten grains of blue vitriol to an ounce of water dropped into the
