This is an inflammation of the udder, sometimes known as "caked bag," with or without general inflammation. Where it is simply an inflammation of the udder, it is usually caused by too great an accumulation of milk in the latter prior to lambing, or in consequence of the death of the lamb. _Treatment._ Drawing the milk partly from the bag, so that the hungry lamb will butt and work at it an unusual time in pursuit of its food, and bathing it a few times in _cold_ water, usually suffices. If the lamb is dead, the milk should be drawn a few times, at increasing intervals, washing the udder for some time in cold water at each milking. In cases of obdurate induration, the udder should be anointed with iodine ointment. If there is general fever in the system, an ounce of Epsom salts may be given. If suppuration forms, the part affected should be opened with the lancet. GOITRE. The "swelled neck" in lambs is, like the goitre, or bronchocele, an enlargement of the thyroid glands, and is strikingly analogous to that disease, if not identical with it. It is congenital. The glands at birth are from the size of a pigeon's egg to that of a hen's _egg_, though more elongated and flattened than an egg in their form. The lamb is exceedingly feeble, and often perishes almost without an effort to suck. Many even make no effort to rise, and die as soon as they are dropped. It is rare, indeed, that one lives. A considerable number of lambs annually perish from this disease, which does not appear to be an epizoötic, though it is more prevalent in some seasons than in others. It does not seem to depend upon the water, or any other natural circumstances of a region, as goitre is generally supposed to, since it may not prevail in the same flock, or on the same farm, once in ten years; nor can it be readily traced to any particular kind of food. When it does appear, however, its attacks are rarely isolated; from which circumstance some have inferred that it is induced by some local or elimentary cause. Losses from this disease have ranged from ten per cent. to twenty, thirty, and even fifty per cent. of the whole number of lambs. Possibly, high condition in the ewes may be one of the inducing causes. _Treatment._ None is known which will reach the case. Should one having the disease chance to live, it would scarcely be worth while to attempt reducing the entanglement of the glands. Perhaps keeping the breeding-ewes uniformly in fair, plump, but not _high_ condition, would be as effectual a preventive as any. GRUB IN THE HEAD. What is popularly known as the "grub" is the larva of the _[oe]strus oris_, or gad-fly of the sheep. It is composed of five rings; is tiger-colored on the back and belly, sprinkled with spots and patches of brown; its wings are striped.
