The accidental causes of this latter (morbid _condition_) are various; a very common one is found in injudicious feeding, both as to quality and quantity. Any sudden alteration in the articles of a horse’s diet will frequently, according to the term of horse amateurs, “_throw him out of condition_,” such as removing him from the grass field or the straw yard to a full allowance of dry hay and corn, with a scanty supply of water “_to draw up his belly_;” all which are perhaps done at once, without the smallest preparation. In these cases the alimentary canal, being hardly yet in a state of digesting capacity, suffers from the increased powers necessary to draw nutriment from substances which, although in themselves more nutritious, yet are, in this instance, less digestible than those before in use. Thence follow costiveness, heat, and thirst; as well as an unhealthy state of the coat, which stares, and feels harsh and dry, being a necessary consequence of the ordinary sympathy between the stomach and the skin. A sudden remove from a generous to a poor diet is unfavourable to _condition_ likewise; for in such case the chyle or nutritious pabulum, from whence all the vital organs are recruited, and all the vital energies derive their vigour, cannot be separated in sufficient quantities: the blood thereby becomes deteriorated; universal absorption takes place of the softer parts, which produces lessened bulk; while a laxity of fibre in the remaining portions is productive of langour and debility. The quality of the food is also of considerable consequence to the _condition_. Mow-burnt hay, by exciting a partial diabetes, is very apt to “_throw a horse out of condition_.” Musty hay, also, and oats highly kiln-dried, have an unfavourable effect on it also. The liquid aliments should likewise be attended to in a consideration of the _condition_. Mineral waters are unfavourable to it in most cases; although there is reason to believe that in some morbid affections they are salutary. Sea-water may be considered in the same light, but a continued use of the brackish water found near sea-bathing places, is unfavourable to the _condition_ of such horses as have not been accustomed to it: to which, in union with the bad care taken of them in most of the livery stables of the sea-coast bathing, I attribute the universal complaint of the ill-condition in which they so frequently return from thence. Badly ventilated stables, excess of clothing, and deprivation of water, are also frequent causes of _morbid condition_, as I have often witnessed: for, in some of these cases, after a course of purgatives, followed by alteratives and tonics, has failed, the more simple means of succulent food, a proper quantity of water, a well regulated but perfectly cool stable, with a free access of air, and very moderate clothing, have created an immediate change. An inordinate quantity of exertion, particularly if continued unremittingly for
