Major in the College of Letters and Science.-(a) Preparation in the Lower Division. The minimum requirement is Chemistry 1A-1B (10), which must be passed with a grade of C or better before any further work in chemistry is taken; Physics 2A-2B or 1A-1в (6); trigonometry, Mathematics 5 (3) or 3A-3в (6) and a reading knowledge of German. The student is recommended to take a second course in chemistry in the lower division and additional work in physics (1c-1D) and in mathematics (9A-9B or 4A-4B) either in the lower division or in the upper division. The department will decide whether a student will be permitted to make chemistry his major on the basis of the student's record in the lower division. (b) Upper Division.-All units in chemistry in excess of fourteen are counted as upper division units when taken in the upper division. The minimum requirement for the major is: quantitative analysis 6A-6B (6) or 5 (3); organic chemistry 8 and 9 (6); physical chemistry 110 (3), and two of the following courses: 100 (3), 111 (4), 120 (3). The remainder of the twenty-four required units may be taken in chemistry or allied subjects in accordance with some definite plan approved for the department, by Associate Professor Eastman, 203 Gilman Hall. The sequence of courses listed for the College of Chemistry in the Circular of Information is recommended. Students who fail to maintain an average of one grade point per unit in the courses constituting the major will, upon approval of the Executive Committee of the College, be excluded from the major in chemistry.

Letters and Science List.-All undergraduate courses except courses 142A-142B and 145 are included in the Letters and Science list. For regulations governing this list, see page 4.

College of Chemistry.-Students in the College of Chemistry are required to submit their proposed schedules to Professor Porter, 114 Gilman Hall. Whether the student intends to prepare himself for research in governmental, industrial, or educational institutions, for teaching, for analytical chemistry, manufacturing chemistry, the chemistry of petroleum, or any of the other branches of chemical engineering, it is desirable that a complete schedule of courses, chosen with a definite purpose and free from conflicts, be arranged at the earliest possible date. A schedule for students who wish to specialize in chemical technology will be found in the announcement of the College of Chemistry in the Circular of Information.

Honors Students in the Upper Division.-Students in the College of Chemistry, and those in the College of Letters and Science who propose to make chemistry their major, are urged, when eligible, to enroll at the beginning of their junior year as candidates for honors. Honors students will be given a larger share of personal instruction and a greater opportunity to choose courses, and work within courses, in the manner best suited to individual needs and aims. Students not in the honors group will not, except under unusual circumstances and with the express permission of the instructor, be permitted to enroll for honors courses (marked H) nor for undergraduate research. Students in the College of Letters and Science enrolled in the honors group will not ordinarily be recommended for honors in chemistry at graduation unless their work includes courses 6A-6B, 8, 9, 110, 114H, 116H, and 180H. Students enrolled in the honors groups should confer with Professor Bray, chairman of the Committee on Honors in Chemistry, 104 Gilman Hall, regarding their plans for the last two years of college work.
