    I . 26 ficial excoriation of a brownish red colour covered with a crust consisting largely of dried blood. But these ulcerations do not degenefa'te into phagedsenic ulcers like those which often occur in cow-pox. The disease is communicable to man, especially when the milk is drunk while still warm from the cows. Vesicles make their appearance on the lips and tongue. M. Hertwig, who drank the milk as an experiment, also suffered from vesicles on the lingero. They ran a less rapid course than those on the mouth. They were filled with a liquid resembling turbid lymph, increased in size, and became confluent at several points; then ruptured, dried up, and the epidermis became detached from the afflicted parts. Yellow-Pock is a disease described by Nissenas an eruption yellow from its first appearance, and continuing so. It is accompanied with an extremely unpleasant—almost putrid—smell, and soon degen- erates into ulcerations, from which pus and blood exude. The disease is communicable from one cow to another, and to man ;3 boils and ulcers resulting. Bluish or Black Pock, is described as forming bluish or black, or livid vesications on the teats and udders, followed by thin dirty brown or black irregular crusts and some degree of impetigo on the interstices near the bases of the teats (Ceely). Warts.—These are of two kinds, “ long narrow pendulous and linear-shaped prolongations, easily removed, and often detached, the other short, thick, compact, broad elevations, lighter in colour generally than the ground from which they rise, of various sizes, from that of a pea to that of a horse-bean, frequently very numer- ous on the teats, where they are found bleeding and partially detached” (Ceely). “ Other eruptions have been observed, but these, like chapped teats and warts, from their description could scarcely be mistaken for cow-pox.” Such are “ suppuration of the cutaneous follicles at the base of the teats; small hard knots, cutaneous or subcutaneous, in the same locality, about the size of a vetch, a pea, or even larger, which often remain indolent for a time, at length become red, vesicate, enlarge, suppurate, and burst after attaining not infrequently the size of a walnut or more, occasion- ally affecting the hands of the milker and often the other cows milked in the same shed by the same hands; an eczematous erup- tion, with intertrigo on the udder and near the roots of the teats ” (Ceely). To this list may be added the condition of the teats which is met with in the cattle-plague. 8 Ceely met with a case which he describes as follows :—“ Not long since I saw a wife and five children labouring under a pustular disease of six weeks’ standing, and infected by the father, who had caught the disease from the cow, which was in a terrible condition. It was of the character of ecthyma, but com- municable, affecting the face, trunk, and limbs, and could be propagated by inoculation.” i
