The elective pamphlet, after its long and thorough revision, has been published, and was distributed yesterday, with the rules governing choice of college studies, which have been published separately.

The courses in Engineering are now placed on a par with other courses, and follow Mathematics in the pamphlet. The Natural History department has been divided into its three branches, Botany, Zoology and Geology; and the advanced Greek and Latin courses are grouped as Classical Philology. The main feature of the pamphlet is the division of courses into three groups,- those designed primarily for undergraduates, those for graduates and undergraduates, and those primarily for graduates. The courses for undergraduates are open to graduates, but are not ordinarily counted towards any of the higher degrees. To the courses primarily for graduates undergraduates are admitted only on recommendation of the instructor.

The corps of instructors has undergone a number of changes. Professors Emerton and J. M. Peirce have returned from their leave of absence and Professors A. S. Hill, Greenough and Goodale will enjoy a sabbatical year. Mr. Sawin's death and the retirement of Messrs. Markley, Anderegg and Bailey have left a gap in the Mathematical department. Dr. Whiting and Mr. Buckingham have retired from the Physics department; Mr. Hendrixson from Chemistry; Mr. Miller from Political Economy; Mr. Grandgent from German; and Messrs. Clymer and Carpenter from English. Their places have been partly filled by the assignment of courses to Mr. Gates in English, Dr. Poll and Mr. Nichols in German, Dr. Marcon in French, Dr. Brooks in Political Economy, Mr. Johnson in Engineering, Messrs. Sabine and Hooper in Physics and Dr. Richards in Chemistry.

In the Italian, Spanish, Political Economy, Fine Arts, Music, Engineering, Physics, Chemistry, Botany and Zoology departments there are no important changes except those mentioned. The Philosophy, Sanskrit, Semitic and Geology departments have already been described in these columns. It remains only to point out a few changes in the other departments. In Greek the new courses are:- 9, Aeschylus; and Classical Philology 23, the Athenian expedition, both under Professor Goodwin; Cl. Phil. 21, Greek dialects, Professor Allen; Cl. Phil. 25, Greek private life, Professor J. W. White; Cl. Phil. 27, Roman architecture and topography, Dr. Tarbell. The English, German, French, History and Mathematics departments make changes too extended for such brief notice as can be given here. They will be described when their special pamphlets are published.
