In further exposition of these views, from men of different pursuits, reference should be made to an article on Classics and Colleges, by Professor Gildersleeve _(Princeton Review_, July, 1878), lately reprinted in the author's "Essays and Studies," (Baltimore, 1890); to an address by Professor Sylvester before the University on "Mathematical Studies and University Life," (February 22, 1877); to an address by Professor Martin on the study of Biology _(Popular Science Monthly,_ January, 1877); to some remarks on the study of Chemistry by Professor Remsen _(Popular Science Monthly,_ April, 1877); and to an address entitled "A Plea for Pure Science" (Salem, 1883), by Professor Rowland, as a Vice-President of the American Association for the Advancement of Science. Although of a much later date, reference should also be made to an address by Professor Adams (February 22, 1889) on the work of the Johns Hopkins University, printed in the _Johns Hopkins University Circulars_, No. 71. An address by Dr. James Carey Thomas, one of the Trustees, at the tenth anniversary, in 1886, may also be consulted _(Ibid._ No. 50). Reference may also be made to the fifteen annual reports of the University and to the articles below named, by the writer of this sketch. The Group System of College Courses in the Johns Hopkins University _(Andover Review,_ June, 1886); The Benefits which Society derives from Universities: Annual Address on Commemoration Day, 1885 _(Johns Hopkins University Circulars_, No. 37); article on Universities in Lalor's _Cyclopaedia of Political Science_; an address before the Phi Beta Kappa Society of Harvard University, July 1, 1886; an address at the opening of Bryn Mawr College, 1885. STUDENTS, COURSES OF STUDIES, AND DEGREES. In accordance with the plans thus formulated, the students have included those who have already taken an academic degree, and who have here engaged in advanced studies; those who have entered as candidates for the Bachelors' degree; and those who have pursued special courses without reference to degrees. The whole number of persons enrolled in these three classes during the first fourteen years (1876-1890) is fifteen hundred and seventy-one. Seven hundred and three persons have pursued undergraduate courses and nine hundred and two have followed graduate studies. Many of those who entered as undergraduates have continued as graduates, and have proceeded to the degree of Doctor of Philosophy. These students have come from nearly every State in the Union, and not a few of them have come from foreign lands. Many of those who received degrees before coming here were graduates of the principal institutions of this country. The degree of Doctor of Philosophy has been awarded after three years or more of graduate studies to one hundred and eighty-four persons, and that of Bachelor of Arts to two hundred and fifty at the end of their collegiate course.
