DISTEMPER, _s._ A disease, a malady. _The Distemper._—No disorder is more general or so destructive as that known by the name of the distemper; it is the most fatal (the plague only excepted) that any animal is subject to. The symptoms of the distemper are not invariably similar, although there are predominant ones which always occur. It generally comes on with a dry husky cough, dullness and want of appetite, a running from the nose and eyes, and loss of flesh. As the disease advances, the dog appears much emaciated, and grows excessively weak, particularly in the loins and hinder extremities; usually there is convulsive twitchings of different parts, most commonly of the head, attended with dimness of sight; when the disease proceeds, and takes on its more virulent form, then the twitches degenerate into continued convulsive fits, the dog foams at the mouth, runs round, and expresses great pain, has a constant disposition to dung, with obstinate costiveness or incessant purging. There is likewise great irritability of the stomach, every thing being thrown up immediately it is taken in, and the animal dies, generally, in one of the spasmodic fits. From this state of the disease hardly any dog recovers, unless from the powerful effect of this gentleman’s medicine, and even then he admits its success doubtful, although he insists, with the medicine early given, the disease will never arrive to this height; but, with every deference to the efficacy of the above medicine, the compiler has known Dr. James’s powder cure the most inveterate stages of the disorder: the method of administering it will be hereafter directed. In every part of this disease a want of nervous energy, and a particular paralytic affection of the nerves, is apparent, and, in some instances, remains long after every other symptom has ceased, and in many respects is not unlike the palsy of the human frame.
