Experience has demonstrated the advantages of general cleanliness, temperate air, (according to the season,) and regular exercise: to the want of these, in part, or all, may be attributed the ills at INNS and LIVERY STABLES, as well as the fashionable increase of Veterinarians. Upon entering the stables of these public receptacles, (particularly if the door has been a few minutes closed,) the olfactory sensations are instantly assailed by such a profusion of volatile effluvia, as to extract moisture from the eyes, in opposition to every endeavour made to restrain it. Here stand rows of poor patient animals, absolutely fumigated with the perspirative transpiration of their own bodies, broiling with _heat_, and panting with _thirst_, in a degree beyond the temperature of a common hot-house, in the severity of the winter season. Each horse is observed to stand upon a load of litter (clean at top, and rotten underneath) very little inferior to a common _cucumber-bed_ in heigth, with all the _advantages_ of equal _warmth_ from the dung _below_! In this unexaggerated state stand hundreds within the environs of the Metropolis; their owners the complete dupes of _ignorance_, _indiscretion_, and _imposition_; the animals themselves in a constant state of languid perspiration, and bodily debility: deprived the comforts of pure air, and regular exercise, they become dull, sluggish, and stupid, as if conscious of, and depressed with, their almost perpetual imprisonment. All this erroneous mode of treatment instantly affects the eye of experimental observation. The carcase seems an incongruous accumulation, evidently full, and unnaturally overloaded, for want of gentle motion, and general friction; the legs become swelled, stiff, and tumefied; and, sooner or later, terminates in _cracks_, _scratches_, _grease_, or some more vexatious disorder. The _hoofs_, by being constantly fixed in a certain degree of heat, begin to contrast, and get narrow at the heels, holding forth the _pleasing_ promise of hoof-bound lameness. The eyes, from a constant watry discharge, give proof of habitual weakness; the lassitude of the body, the heat of the mouth, the general gloom, and every corresponding circumstance, seems to display a frame the reverse of those whose health is preserved, and condition promoted, by a system of discipline opposite in practice, and different in effect.
