Dr. John Roche, an English physician who has had remarkable experiences, gives as his conclusion that cholera is purely and simply a specific fever, only inferior in its ravages to yellow fever, and closely allied to it. Cholera has a period of incubation varying from two to fourteen days; prone to attack the enervated and those subject to depression from any cause. It is contagious, and liable to occur periodically about every ten years in some parts of India. It seems to have visited the British Isles about every sixteen years, and as the period has elapsed since the last outbreak, it is more than likely to occur this year. Those persons who indulge in no enervating habits, and take nothing internally which would arrest the secretions nor too drastically stimulate them, and partake of nothing which is highly fermentable, may safely feel that they are cholera-proof during an epidemic. * * * * * “The Old South Lectures for Young People” is a pleasing and successful plan for teaching the History of America. Lectures are held Wednesday afternoon at the “Old South Meeting House,” Boston, and the subjects illustrate well the tenor of the meeting. Thus for September the topics are “Franklin,” “How to Study American History,” “The Year 1777,” “History in the Boston Streets.” * * * * * In the C. L. S. C.
