several days, will often produce _morbid condition_; and this in cases where the feeding has been, as supposed, equal to the tasks required. It is particularly likely to happen to young horses, and to such as have not been sufficiently prepared: in which cases, it is clear that the stomach, participating with the general debility, has a double task to perform in digesting a larger quantity of nutriment than usual, to make up the increased wants of the constitution; and thus the evil is increased by adding the further deterioration of this organ to the others. I know of no state of morbid condition which often proves so obstinate as this; and which is often found at last only to give way to a good salt-marsh run. Drastic purgatives, or violent remedies, as the mineral acids, when injudiciously continued, reduce the _condition_ very quickly, and sometimes irrecoverably. Another principal cause of want of condition is the alternation of heat with cold. A sudden check to the natural or acquired heat of the body, particularly if aggravated by the evaporation of a perspiring state, and great previous exertion, as a sudden check after a severe burst with the hounds. * * * * * After a general enumeration of the causes of morbid condition, Mr. Blaine continues:—But to proceed with this important subject with some regularity, I would direct that in young plethoric horses, with much flesh on them, and which are, of all others, the most subject to take on this state of _morbid condition_, that one or two moderate bleedings may be premised, particularly in such as have been full fed for some time previous. If the inner surface of the eyelids, or of the nasal membranes, show any tinges of red, it is still more necessary to bleed; and in such cases I would repeat the same with moderation once or twice more, or until this inflammatory appearance should be removed. I have found this, united with mashing, in many instances sufficient to relax the hide and reduce the rugous tumefaction of the lampas. In most cases, however, some more active internal remedies will be found necessary with a young and plethoric patient: thus one or two very mild doses of physic, preceded by a nightly mash, into which ten grains of submuriate of mercury (calomel) has been mixed, are proper. If there be joined to the affected hide, and the swollen or clammy mouth of lampas, any eruptions on the skin, or any cracks of the heels, stable soiling, or even daily turning out to grass, are advisable; but as these cases usually happen when the animal is either at present wanted, or is intended soon to be used, so I have not mentioned _turning out_ altogether; yet, if these appearances prove obstinate, such a course will be advisable, provided the season and other circumstances are favourable to the proceeding. But when neither the partial nor total turning out to grass is convenient, and when soiling is likewise not
