The body, when opened, generally displays a condition which, from the outward signs, was far from expected. The internal organs are covered with tumors. Numberless morbid growths, of various dimensions and in every stage of development, crowd upon every part. These readily account for that disinclination to move which characterized the latter days of existence. [Illustration: THE SIGN THAT TELLS OF THE EXISTENCE OF MELANOSIS.] There is one test for melanosis which does not invariably meet with a response, but which, when successful, seldom deceives. This is a pimple near to the root of the dock; it is very rarely of magnitude; there may only be one or there may be several, and the largest may not exceed the dimensions of half a pea. When, however, such an indication can be detected upon a gray horse which is turning white, the evidence is almost conclusive. The author does not know an instance, where it has suggested the presence of melanosis, that the post-mortem examination has contradicted the indication. With regard to the ultimate termination of this disorder, the author has no experience. Horses thus affected are always slaughtered when the second stage interferes with their utility; but, judging from the similarity of the disease in man and in the animal, it is conjectured the last stage in each would be alike. WATER FARCY. =Water farcy=, like so many equine disorders, is the offspring of weakness. Man, having a servant willing to work and incapable of complaining, too often proportions the toil only to the master's desire or the master's convenience. Many horses--which perform slow labor--are in harness eighteen hours out of the four and twenty; their rest is while the carter drinks, eats, and sleeps. No, not even can they enjoy such brief respite as is afforded by avarice to the laboring fellow-being; often is one of the drivers seen soundly sleeping on the top of the load which the stiff and jaded animals are compelled to draw. Thus the horse's toil is almost constant; wagoners are well aware that many horses sleep while in the shafts or in the chains. Overcome by fatigue, the animals doze, but continue to walk and to pull the burden onward. Who, knowing such a fact, can wonder that a living frame thus abused should often bow beneath its yoke, and, through death, set torture at defiance?
