LAMENESS IN HORSES—proceeds from a variety of causes, and requires much patient investigation to ascertain, to a certainty, the exact seat of injury; for want of which judicious precaution, mischief frequently follows. Horses are sometimes _persecuted_, _blistered_, and _fired_, for a LAMENESS in _one_ part, which ultimately proves to be in _another_; and this alone sufficiently points out the absolute necessity of a deliberate discrimination. As lameness proceeds from different causes, so it is of different kinds, and requires various modes of treatment, equally opposite to each other. This cannot be more forcibly elucidated, than by adverting to the difference between a lameness originating in a relaxation of the SINEWS, and a ligamentary injury sustained by a sudden _turn_, _twist_, or _distortion_, of some particular JOINT. These require a very different mode of treatment; and yet it is too much, and too unthinkingly the custom, to treat every kind of lameness in the same way. From either a want of patience in the owner, or a want of prudence in the practitioner, the favourite operation of BLISTERING is thought applicable to _every case_ without exception; and being often resorted to before the inflammation of the part has sufficiently subsided, occasions a permanent enlargement, with a thickening of the integument, and consequent stiffness, rendering the remedy equally injurious with the original defect. In all lamenesses occasioned by a relaxation of the TENDONS, blistering, and even firing, are admitted to have a forcible effect, provided they are brought into use at a PROPER time; but not _before_ the inflammation (which is generally attendant upon such case) has previously subdued. In all ligamentary injuries, BLISTERING is seldom, if ever, known to be productive of permanent advantage; and is, perhaps, upon most occasions, so immediately adopted, because a _single_ application is of so much less _personal trouble_, than a daily persevering hour bestowed in hot FOMENTATIONS, and stimulative EMBROCATIONS. Upon the subject of lameness in general, it is necessary to remark, that injuries sustained in the tendons (commonly called the back sinews) are more frequently relieved, and a lasting cure obtained, than in a lameness of the joints; where, after patient and persevering medical applications, and a corresponding portion of REST, a renewal of work has almost immediately produced a relapse.
