_Remarks._--As prevention is much more convenient and less expensive than the fashionable system of making a chemical laboratory of the poor brute's stomach, the author would remind owners of stock that the practice of turning the latter into green, succulent pasture when the ground is damp, or permitting them to remain exposed to the night air, is among the direct causes of hoove. The ox and many other animals are governed by the same laws of nature to which man owes allegiance, and any departure from the legitimate teachings, as they are fundamentally ingrafted in the animate kingdom by the Omnipotent Creator, is sure to subject us to the penalty. We are told that, during the night, noxious gases and poisonous miasmata emanate from the soil, and that plants throw off excrementitious matters, which assume a gaseous form, and are more or less destructive. Now, these animals have no better powers of resisting the encroachments on their organization (through the agency of these deleterious gases) than we have; they must have atmospheric air to vitalize the blood; any impurity in the air they breathe must impair their health. Still, however, the powers of resistance are greater in some than in others; this explains the reason why all do not suffer. Sometimes, the gases are not in sufficient quantities to produce instant death, but only derange the general health; yet if an animal be turned into a pasture, the herbage and soil of which give out an excess of nitrogen and carbonic acid, the animal will die; just as a man will, if you lower him into a well abounding in either of these destructive agents. From these brief remarks, the farmer will see the importance of housing domestic animals at night. JOINT MURRAIN. This malady, in its early stages, assumes different forms; sometimes making its appearance under a high grade of vital action, commonly called inflammatory fever, and known by the red appearance of the sclerotica, (white of the eye,) hurried breathing, expanded nostrils, hot tongue, and dry muzzle, pulse full and bounding, manifestations of pain, &c. &c. Different animals show, according to local or constitutional peculiarities, different symptoms.
