THE COURSES IN CHEMISTRY The Department of Chemistry offers a four-year course leading to the degree of Bachelor of Chemistry. Graduates who have ful filled the requirements for this degree, or the substantial equivalent thereof, may obtain either the degree of Master of Chemistry or the degree of Chemical Engineer by completing satisfactorily one addi tional year of study The additional year of residence required for either of these degrees may, upon recommendation of the student's special committee, be accepted as satisfying one year of the residence requirement for the degree of Doctor of Philosophy. The four-year course leading to the degree of Bachelor of Chemistry is not a pre requisite for the degrees of Master of Arts, Master of Science, or Doctor of Philosophy with major subject in Chemistry. [61 DEPARTMENT OF CHEMISTRY 7 THE DEGREE OF BACHELOR OF CHEMISTRY The degree of Bachelor of Chemistry will be awarded to those who have satisfactorily completed either of the following curricula, and the requirements prescribed by the University in Hygiene and Preventive Medicine and in Military Drill or in Physical Training. The completion of Curriculum No. 2, or its substantial equivalent, is required for admission to the fifth year of study leading to the degree of Chemical Engineer (see page 9) . Since the first two years of work are identical in the two curricula, the student is afforded ample time to discover whether his interests lie chiefly in the field of pure chemistry or in the field of chemical engineering before he is compelled to decide upon his further course of study.

The first three years of the university work of a candidate for the degree of Bachelor of Chemistry are devoted to training in fundamen tal theories, applications, and methods, of chemistry and of allied sciences. By the fourth year the student should have some idea as to the field of chemistry which is most attractive to him, and should be looking ahead toward his career after graduation. It is eminently desirable that the choice of electives should be made after such con sideration, and the student is advised to consult with his class adviser during the junior and senior years in order that this may represent a certain continuity of purpose. Where electives are included in the sophomore or junior years these should be selected so as to insure adequate preparation for any specialized study in the senior year. The elective hours of the senior year may be devoted to courses in the "humanities," or in allied sciences such as Physics, Geology, Botany, and Biology, or to ad vanced courses or research in Chemistry. By a proper choice of elec tives, the student who wishes to secure amore extensive training than is offered in the Courses in Chemistry may extend his studies over five years, interspersing additional elective courses throughout this period. Such a five-year course is particularly recommended for students desiring a broadly cultural training in addition to their specialized work in Chemistry. OPPORTUNITIES FOR EMPLOYMENT AFTER GRADUATION The student's occupation as a chemist after graduation is likely to fall into one of the following classes : Inspection and control, in industrial, institutional, or government laboratories, Supervision of operation in chemical plants, Research and development, Technical sales or technical purchasing, Teaching. A committee on Employment has charge of finding suitable posi tions in the above fields. o m^ o Z m-< ti o H o Q O H Z ii O >< ti o 2 DEPARTMENT OF CHEMISTRY 1 5 THE BAKER LABORATORY OF CHEMISTRY The general equipment of the laboratory and the administration of its various facilities are planned to give the maximum opportunity for unhampered work in the various fields of chemistry. Materials may be subjected to temperatures ranging from those of the electric furnace to that of liquid air, to extreme pressures or high vacua, to electrolysis or to the action of various radiations ; theymay be studied microscopically, spectroscopically, or by means of x-rays, and the production may be carried out under the exacting conditions of re search or in semi-plant scale apparatus. The aim has been to enable chemical behavior to be studied under the widest possible variety of conditions, and by all the different methods used by chemists. On the instructional side, these special methods are available for the demonstration of the whole range of properties of chemical sub stances, and for the training of students in their observation and interpretation. The building in which the Department of Chemistry is housed was given to theUniversity by George Fisher Baker. The close co-opera tion between the Staff of the Department and the architects and engineers engaged in its construction is responsible for scope and facilities hardly to be surpassed. Some four acres of floor space are available for purposes of instruction, which is given to over 2,000 students every year ; the number of registrations in Chemistry courses exceeds 4,000 annually. Exceptionally complete administrative and engineering equipment takes up an additional acre of floor space. Each of the Divisions of the Department occupies a group of rooms, adjacent to the offices of the instructors in charge, and pro vided with special plumbing and electric current as required. Dis tilled water, steam, circulating hot water, cold water, gas and com pressed air are supplied to all lecture rooms and laboratories, the last three being supplied to all individual desks. Amotor generator set in the basement furnishes direct current of constant potential, 55 or no volts, by means of a three-wire system, to all the advanced labora tories. A number of these are also connected with a storage battery current for lower voltages. A second motor generator set having a capacity of 2,000 amperes, D.C. or A.C., supplies the heavy currents necessary for electric furnace work, and a special high frequency con verter is used in connection with an Ajax-Northrup induction furnace. The building is ventilated by two separate sets of electrically driven fans which are located in the attic. One set supplies fresh air to all rooms, while the other exhausts air from the hoods in the various laboratories. These hoods are of the open front type, and each is vented to the exhaust flue at the top and bottom of a "baffle-plate" at the back. The laboratory table tops, sinks, hoods and much of the shelving in the building are of alberene stone.

A mechanician, in charge of a completely equipped shop, is avail able for the construction of special apparatus. An equipment for the production of liquid air, owned jointlywith the Department of Physics and housed in the neighboring Laboratory of Physics, Rockefeller Hall, is of such capacity as to furnish an abundant supply of liquid air for lecture demonstrations and investigational purposes. A locker room with showers, men's and women's rooms, and numerous coat rooms are provided for the convenience of the students and a first aid room is equipped to care for minor accidents. The main lecture room, seating 476, is so arranged, that all the seats are within 5 5 feet of the lecture table. It is equippedwith rapid- acting shutters, so that it may conveniently be darkened for showing slides or motion pictures. Five other lecture rooms, all containing projection lanterns, communicate through their preparation rooms by electric elevatorswith themuseum. A number of recitation rooms are also provided. The Museum, through which the main lecture room is reached, is part of the working equipment of the Department and is used as a repository for much of the illustrative material used in the various courses. It contains, in addition to specimens of synthetic and naturally occurring chemical substances, an extensive collection of raw materials and finished products of industries exemplifying the more important commercial chemical processes. The Department Library is very fully supplied with works of reference and standard books on chemistry and allied subjects, num bering about 8,000 volumes in all. The current numbers of some seventy-five periodicals are on file in the reading room. In addition the facilities of the library are supplemented by the various other libraries of the University which contain extensive collections of works in other fields of science and engineering. The reading room is open evenings. Advanced students have the privileges of the stack room. 20 CORNELL UNIVERSITY Lectures.
