XX. THE. DEPARTMENT OF CHEMISTRY

OFFICERS OF INSTRUCTION

JOHN ULRIC NEF, PH.D., Professor and Head of the Department of Chemistry.

ALEXANDER SMITH, PH.D., Professor and Director of General and Physical Chemistry.

JULIUS STIEGLITZ, PH.D., Professor of Chemistry.

Herbert NewBY MCCOY, PH.D., Associate Professor of Physical Chemistry. THOMAS B. FREAS, A.B., Curator.

EDITH ETHEL BARNARD, PH.D., Instructor in Chemistry.

ANDREW FRIDley McLeod, PH.D., Research Instructor in Chemistry.

WILLIAM WELDON HICKMAN, A.B., Research Assistant.

ETHEL MARY TERRY, A.B., Assistant.

LAUDER WILLIAM JONES, PH.D., Professor of Chemistry, University of Cincinnati (Summer Quarter, 1909).

The Department aims to prepare students (1) to teach in colleges or universities; (2) to teach in secondary schools; (3) to fill positions as technical experts or assistants in chemical industries; (4) to become analysts in commercial and sanitary laboratories. The elementary courses may be taken with advantage by students having none of these ends in view.

Special stress will be placed on thoroughness of preparation and the symmetrical development of the student's knowledge. The object of the courses will be not so much to train specialists as to prepare the student to undertake intelligently all kinds of work of a chemical nature. Those intending to become practical chemists will find a thorough course of purely Scientific Chemistry the best basis for future specialization in any branch of the subject. Those who incline toward Inorganic Chemistry will be required to do much physical and a considerable amount of organic work; those proposing to become organic chemists will be required to do work in Inorganic Chemistry of a more advanced nature than that given in the elementary and analytical courses, and some Physical Chemistry, and so forth.

RESEARCH

Students are encouraged to begin research work as soon as their preparation justifies it. Facilities for research in all lines, whether of Inorganic, Organic, or Physical Chemistry, are provided. Special opportunities to pursue entirely independent research work will be given to maturer students who have already obtained the Doctor's degree.

DEGREES

The degree of Doctor of Philosophy: Chemistry the major subject. — The requirements for the degree of Doctor of Philosophy are: (1) the presentation of a thesis embodying the result of original research in General Inorganic, Organic, Physico-Organic, or Physical Chemistry. The work on which the thesis is based is usually done under the direction of an officer of the Department. (2) Especially thorough and mature knowledge of the branches of Chemistry touched by the thesis, and sufficient knowledge of other fundamental branches of the science.

The general requirements for all candidates are as follows: courses 1-3 (or 1A, 2A), 4,1 6-9, 60, and 61, and two majors selected from courses 10, 11, 13-19, and 30-32; total twelve majors, of which eight majors are undergraduate work.

Special requirements in addition to the above, arranged according to the thesis subject, are as follows:

General Chemistry.-Courses 50-52, 35 or 63, and two majors taken from courses 13, 30, 31, 32, 36, 37, 63, 64, and 65; total, 6 majors.

Organic Chemistry.-Courses 32, 35, 36, 37, and 50, and one major from courses 10, 13–19, 51, 52, and 63-65; total, 6 majors.

Physico-Organic Chemistry.-Courses 31, 35, 36, 50, 36 37, 50 or 63, and one major taken from courses 10, 13-19, 51, 52, 63, 64, and 65; total, 6 majors. Physical Chemistry.-Courses 50, 51, 63 and 64, and at least two majors taken from courses 10, 13-19, 30-32, and 35-37; total, 6 majors.

In addition to one set of these specific requirements, at least six halfmajors will be chosen from the special lecture courses, 40-44, 53-58, 65–71, and 80-81. The research work will require from four to six quarters.

The degree of Doctor of Philosophy, Chemistry the secondary subject.— When Chemistry is a secondary subject, the requirement is determined after conference with the head of the Department in which the major work is done. Courses 2, 3, 6, 7, and 8, and four other majors in advance of 8, will be required when Chemistry is the only secondary subject; courses 2, 3, 6, 7, and 8, and one other major, when Chemistry is one of two secondary subjects. Elementary Physical Chemistry (60 and 61) or Organic Chemistry, according as the major subject belongs to the Physical or the Biological Group, is recommended.

The Master's degree.-For the Master's degree a dissertation and eight majors of graduate work in Chemistry are required if all the work is in this Department. These majors must be selected from courses in advance of 9, with the approval of the head of the Department. Courses prerequisite to these must be taken, but cannot be counted in reckoning the eight required majors.

SPECIAL COURSES NOT LEADING TO A HIGHER DEGREE

Special students.-Special or unclassified students, not candidates for a degree, will be received, but in every case they will be required to give evidence, satisfactory to the instructors, that their previous training has been sufficient to enable them to derive full profit from the courses they propose to take.

Preparation for teaching.-While students who have not taken the work required for the Doctor's or Master's degree are not usually recommended for college or university positions, the Bachelor's degree, with a sufficient amount of work in Chemistry, is at present considered preparation for teaching in secondary schools. In general the work in Chemistry should include courses 1, 2, 3, 4, 6, 7, 8, 60, 61, and 80, or their equivalent, as well as work in the College of Education. The prospective teacher in secondary schools should be prepared to teach at least one science besides Chemistry.

1 Course 4 may be omitted when advanced work in Organic Chemistry is taken.

Preparation for technical positions.-1. Thorough scientific training in all branches of Chemistry required for the Doctor's degree forms the best basis for a career as a chemical expert in any branch of chemical industry. With this preparation, the principles and details of technical processes are quickly grasped, advances in industrial processes are intelligently followed, and newly discovered principles are readily applied.

2. Students who have taken from ten to fifteen majors of work in the Department are able to fill satisfactorily positions as assistants in technical and analytical laboratories, and, after some practical experience, to advance to positions of independent responsibility. Students should take at least courses 1-10, inclusive, one or two majors in courses 13-19, and courses 60 and 61. If the student's work is primarily in Organic Chemistry, he should take, if possible, two or three courses selected from Nos. 30-32 and 35-37; if his work is in Inorganic Chemistry primarily, he should take courses 5052. Students taking the fuller preparation outlined are given the preference in answering requests received by the Department; but students with less complete training are also sought by technical firms.

3. The Department gives, with other departments (notably Physics and Mathematics) of the University, and the Department of Manual Training of the University High School, the equivalent of three years of a four-years' course in Chemical Engineering. Students are able to take a large part of this work in the purely scientific fundamental branches while they are candidates for a Bachelor's degree.

The Department does not pledge itself to secure positions for those who have studied in it, but, as a matter of fact, competent students find suitable places quickly, and in the past the demand for chemists has far exceeded the supply.

LABORATORY FEES

There is a laboratory fee of $5 per major for all courses involving laboratory work in the Department of Chemistry.

COURSES OF INSTRUCTION

NOTE.-After course 9, the courses are arranged in groups according to subjects: courses 10-29 include courses in Analytical Chemistry, 30-49 in Organic Chemistry, 50-59 in Inorganic Chemistry, 60-71 in Physical Chemistry; 80-89 are general in nature, and 90-93 are research courses. Nos. 12-19, 30-34, 40-43, 60–62, and 68-71 are open to, and suitable for, Senior College students.
