Several new courses are offered in the Department of Mathematics. Course 24-a half-course on the theory of numbers-will be given by Professor Bocher.
Course 22, a half-course on the theory of surfaces, is offered by Professor B. O. Peirce.
Professor J. M. Peirce will give course 23 on the special development of the calculus of quaternions.

Courses 6, 14, 7b, and 11 give place to courses 7a, 9, and 16.
In the Department of Engineering a few changes have been made. Course 1a has been split into three half-courses, 1a, 1b, and 1d. Course 1f has been introduced to supplement course 1c.
Two new courses have been added by the Department of Physics. Course 7, a half-course on the theory of probability and the kinetic theory of gases is offered by Professor Hall. Course 20d, for advanced students, is offered by Professor Sabine. Course 9 embraces former courses 9 and 10, and will be conducted by Professor B. O. Peirce.
Chemistry 2-a new elementary half-course on organic chemistry-will be given during the first half-year by Mr. Torrey.
The Department of Botany offers two new courses. Professor Goodale will give course 5, a study of systematic and economic botany; and Professor Thaxter offers course 6-a study of the special morphology and classification of cryptograms.
In the Department of Zoology, the work in courses 6 and 7 has been divided. What was formerly course 6 is now courses 10 and 11, to be given in alternate years by Dr. Davenport. Next year course 11 will be given.
Courses 15 and 16-two half-courses regularly given in alternate years-embrace the subject of the nervous system and its terminal organs, formerly treated of in course 7. This year course 16 will be given during the first half-year by Dr. Parker.
An important change has been made in the Department of Geology. Formerly Geology 4 has embraced both lectures and field-work. Next year, however, it is to be given only as a half-course, consisting entirely of lectures.
To supply the field and laboratory work, course 5 will be given as a half-course during the last half-year.
Courses 9 and 11 have been dropped from the list. A new half-course on experimental and dynamical geology-Geology 17-will be given during the first half-year by Mr. Jaggar.
Course 7 will not be given; and courses 6, 26 and 19 will be offered.
Mineralogy 7 and 8 are too half-courses, which will be given in successive half-years, and include the work formerly done in course 7.
These are the principal changes which have been made in the courses for next year. Further information will be found in the elective pamphlet, which can be obtained at University 2.
