C. L. S. C. NOTES ON REQUIRED READINGS FOR JUNE.

Inoculation for cholera is the latest preventive. A number of people have tried it in Valencia, Spain, and with perfect success, the authorities contend. Cholera virus is used. The patient becomes prostrated with a tumor in about twenty-four hours, but usually recovers in a couple of days. Certainly, if as sure as speedy, humanity has found a boon. It will be wiser, however, to wait until the cholera attacks Valencia before trusting too implicitly to inoculation for cholera.

Unbounded curiosity has been displayed at the New Orleans Exposition, over the “Woman’s Department.” In spite of fate Mrs. Julia Ward Howe and her co-workers have succeeded in making it a success, and in getting a fair representation of what women can do. They have a literary department filled with scores of volumes written by women, a woman’s exchange, samples of ten thousand kinds of fancy work, of course, and, better than that, of engraving, wood-carving, drawing, silk culture and weaving; a novel niche is made by a display of patents taken out by women, and by blacksmith work and forging done by women. Could they transport a cottage with its inmates and let the work of home-making go on day after day, they would add the crown to their department.

Mrs. Elizabeth Cady Stanton in the North American makes the remarkable statement that women have never been benefited by Christianity, but that their elevation is altogether due to the spread of Teutonic respect for noble women. One must naturally conclude that Mrs. Stanton has not studied her history thoroughly. Her statements sound very much like an attempt to build up a theory without respect to the facts in the case. Certainly no fact is better established than that with the spread of the doctrines of Christ came the elevation of women.

CHEMISTRY.

Errata.—The first line of the second experiment, page 441 of The Chautauquan for May, should read: “A body is buoyed up in water by a force equal to the weight of the water it displaces.”
