A near approach to this tumour-form sometimes, it is true, is found in children in par- ticular states of health, or in those of phlegmatic habits, otherwise healthy, with thick skins, where the vesicle, of a rose or damask hue, rises boldly, and in a solid foim, above the level of the skin, covered with an ash-coloured or bluish epidermis, which being punctured, like that on the cow, yields scareely anything but blood even till the tenth day.” Among the miscellaneous points noted in the natural history by Ceely are the following : “ In passing through a largo number of cows it has appeared to me generally milder in the latest than in the first subjects, and I have certainly succeeded in effecting a mitigation by artificial means while in the prosecution of experiments with another view. “ Its topical severity depends almost wholly on the rude traction of the milkers. “ There is no derangement of health either in the animal primarily affected or in those secondarily affected. . . . The animal continues to feed and graze apparently as well as before. “In the same dairy at the same time with the true disease, some one or other of the spurious forms may occur in some individuals [cows], causing difficulty in milking, and producing deep sores on the milkers’ fingers, thus complicating the investigation and deceiving the indiscriminating milkers. “ Occasionally warty or fungous growths succeed some of the deeper ulcerations.” Ceely’s description of the pox of the milch cow’s teats is of the realistic order. It is commendably free from theo- retic bias, and it is by far the richest in detail of any that has been given ; moreover', it bears out the original data of Jenner, and the average testimony of the country, as col- lected by Pearson. We may sum it up briefly as follows : An
