In the conditions which are stated below, it will appear that there are several tests of the proficiency of the candidate, in addition to the constant observation of his instructors. A carefully prepared thesis must be presented by the candidate on a subject approved by his chief adviser, and this thesis must receive the approbation of the Board. There are private examinations of the candidate, both in his chief subject and in the subordinate subjects. If these tests are successfully passed, there is a final oral examination in the presence of the Board. As an indication of the possible combinations which may be made by those who are studying for the degree of Doctor of Philosophy, the following schedule is presented: Physics, Mathematics, and Chemistry; Animal Physiology, Animal Morphology, and Chemistry; Chemistry, Mineralogy, and Geology; Mathematics, Astronomy, and Physics; Sanskrit, Greek, and Latin; History, Political Economy, and International Law; Greek, Sanskrit, and Latin; French, Italian and Spanish, and German; Latin, Sanskrit, and Roman Law; Latin, Sanskrit, and German; Assyriology, Ethiopic and Arabic, and Greek; Political Economy, History, and Administration; English, German, and Old Norse; Inorganic Geology and Petrography, Mineralogy, and Chemistry; Geology and Mineralogy, Chemistry, and Physics; Romance Languages, German, and English; Latin, Greek, and Sanskrit; German, English, and Sanskrit. While students are encouraged to proceed to academic degrees, the authorities have always borne in mind the needs of those who could not, for one reason or another, remain in the university for more than a year or two, and who might wish to prosecute their studies in a particular direction without any reference to academic honors. Such students have always been welcome, especially those who have been mature enough to know their own requirements and to follow their chosen courses, without the incentive of examinations and diplomas. PUBLICATIONS, SEMINARIES, SOCIETIES. The Johns Hopkins University has encouraged publication. In addition to the annual Register or Catalogue, the report of the President is annually published, and from time to time during the year "Circulars" are printed, in which the progress of investigations, the proceedings of societies, reports of lectures, and the appearance of books and essays are recorded. Encouragement is also given by the Trustees to the publication of literary and scientific periodicals and occasionally of learned essays and books. The journals regularly issued are: I. _American Journal of Mathematics_. S. Newcomb, Editor, and T. Craig, Associate Editor. Quarterly. 4to. Volume XIII in progress. II. _American Chemical Journal_. I. Remsen, Editor. 8 nos. yearly. 8vo. Volume XIII in progress. III. _American Journal of Philology_. B.L. Gildersleeve, Editor. Quarterly, 8vo. Volume XI in progress.
