Its advent is announced by swelling about the joints, accompanied by the most painful lameness; the animal may not dare to put its foot to the ground. Often the disease flies about, now seizing upon one or two joints, next attacking the hitherto free members, and generally clinging to similar parts, as the hocks, knees, etc. Then it will return to its former abode--thus shifting about, to the torture of the animal and the confusion of him who may undertake its relief. One almost constant symptom is an increase of synovia. For synovial membrane, whether in the sheaths of tendons or on the heads of bones, rheumatism always displays a marked partiality. This structure is, as has been already noticed, without sensation during health; in disease, however, its involvement communicates extreme agony. The afflicted horse stands with difficulty; its pulse and its breathing declare its sufferings--both are quick and jerking; the limbs may be greatly swollen; and the parts secreting joint-oil bulged out, soft, and puffy, from the increase of their contents. No disease is accompanied with such long and extreme pain as rheumatism; the remedies, therefore, should be quick and effective. Procure the steaming apparatus recommended for bronchitis; fill the warm, loose box, into which the horse should be brought, with vapor; while that is being accomplished, get ready the slings; put the belly-piece under the animal, and fix them so as not to take the entire bearing from the ground, but so as to relieve the diseased joints of some portion of their burden, and allow the horse to rest its body when it is disposed to repose. [Illustration: THE STEAMING APPARATUS USED IN BRONCHITIS.] Keep up the steam for one hour; at the end of that period, have several men ready with dry cloths--wisps would be too exciting; let the men wipe the horse quite dry, with as little noise and as much speed as possible. This over, order some of the assistants to put on the hood and clothing, also wrapping the sound limbs in flannel; the disengaged helpers are to go upon their knees and rub into and about the seat of disorder a liniment thus composed:-- Compound soap liniment Sixteen ounces. Liquor of ammonia Two ounces. Tincture of cantharides Two ounces. Tincture of opium Two ounces. When the liniment has been applied, incase the affected limbs in warm flannel.
