During the past winter, the Lowell Institute in Boston, in connection with the government of the Massachusetts Technological Institute, took a step which deserves public mention. They advertised classes for both sexes, under the most eligible professors, for instruction in French, mathematics, and natural science. As the training was to be thorough, the number of pupils was limited, and the _women_ who applied would have filled the seats many times over. These classes have been wholly free, and have added to the obligation which the free Art School for women had already conferred. On the 25th of June, 1865, the Ripley College, at Poultney, Vt., celebrated its Commencement. Seventeen young ladies were graduated. Ralph Waldo Emerson delivered the literary address, and two days were devoted to the examination of incoming pupils. Feeling very little satisfaction in the success of colleges intended for the separate sexes, I take more pleasure in speaking of the Baker University, in Kansas, which was chartered by the Legislature of that State in 1857, as a university for both sexes. It has now been in active operation for seven years. A little more than a year ago, Miss Martha Baldwin, a graduate of the Baldwin University at Berea, Ohio, was appointed to the chair of Greek and Latin. She is but twenty-one years of age, but was elected by the government to make the address for the faculty at the opening of the Commencement exercises, and seems to have given entire satisfaction during the year. Howard University was chartered at the last session of Congress, for the education of all classes of students, without distinction of sex, race, or color. It has purchased three acres of land in a pleasant part of Washington, and is now ready to receive about twenty-five students. Rev. Dr. Boynton, chaplain of the House of Representatives, is President of the Board of Trustees. St. Lawrence University, Canton, N.Y., a university still very young, graduates both men and women, on precisely the same conditions. Civil engineering and political economy are the only optional studies with the women. It reports one theological student. Lombard University, Galesburg, Ill., does the same; but I know nothing of its standard of scholarship. It is only within the last year that I have been able to visit the most conspicuous colleges in this country in which women are taught with men. I consider the system of mixed classes an immense advantage, as it secures the standard of scholarship, prevents all foolish hazing, and places personal character and moral deportment in their right relations to classic study. It prevents also such instruction in the classics as must necessarily deprave the estimate of woman. OBERLIN.
