. The diseases and disorders of the ox, with some account of the diseases of the sheep. DISEASES OF THE OX AND SHEEP. 345 over to Dr. Klein for purposes of research at the Brown Institution. Dr. Klein proved that micro-organisms existed in the fluid of the vesicles, and that these micrococci could be readily cultivated and grew abundantly in milk; that the disease imparted by the inoculation of calves with the virus presents symptoms very like those exhibited by the cow from which these micrococci were taken, symptoms, moreover, very similar to those of human scarlatina, and accompanied by similar pathological changes in the kidneys and other internal organs. He, moreover, also found that these micro-organisms were, in all essential respects, similar to those which he obtained from the blood of human beings affected with scarlatina. With this short resume of the leading facts, we now proceed to deal with this question more fully. It appears, then, that, as well as Mr. W. H. Power and Dr. Klein, Dr. Cameron also was concerned, though in a less degree, in the investigation of this disease which occurred in milch-cows at Hendon, and gave rise to scarlatina in persons using the milk supplied from that dairy. Now, this Hendon cow disease presents some points in common with a malady of cows called erythema mammillarum,. Fig. 40.—Milk or Teat-Syphon. This rnilk-sypbon constructed for the purpose of abstracting milk from the teats of a cow. or sore teats. As in the case of the Hendon disease, so also in that of this latter malady, cows which have recently calved are those affected, and the ulcers on the teats and udder may in both diseases assume a very sluggish character. The disorder varies in intensity, sometimes affecting the gland tissue itself. The calf should be removed and fed by hand, and the milk should be drawn off daily by tTie aid of a milk- syphon, and, of course, rejected. The attendance of the veterinary surgeon should be sought, and he may probably ad
