Liability of Negroes to Cholera.

An impression appears somehow or other to have got abroad that negroes are not liable to be attacked with cholera; such a notion, however, has no foundation. In New York, it has been observed that they have enjoyed no greater immunity than the whites, and the natives of India, whose constitution much resembles that of the negro, were more liable to cholera than Europeans. There is ample grounds for fearing that the disease will be productive of terrible mortality among the slaves of the southern states, and proper measures of hygiene should be promptly adopted; and on the very first symptoms of derangement of the digestive organs, remedial measures immediately resorted to.
