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 elective courses required in the curriculum may be chosen by the student,

in each case with the approval of his (^) adviser, from the (^) advanced courses in Chem

istry, or^ from^ courses^ in^ other^ departments^ of^ the^ College^ of^ Arts^ and^ Sciences,

or in other colleges of the University.

Students in the Courses in Chemistry may not register for more than 19 hours a

term (not including Hygiene) without first securing the consent of the Depart

ment. A student who does not pass at least (^) twelve hours in (^) any term, with a grade of

C or better in at least six of the twelve hours, may be dropped from the University

or placed upon probation. The same (^) penalty may be (^) imposed upon students in

the Summer Session, who do not pass four hours, with a grade of C or better in at

least two hours.

If, in^ the^ opinion^ of^ the^ Staff^ of^ the^ Department^ of^ Chemistry, a^ student's

general record is (^) unsatisfactory the Staff (^) may recommend that he be refused per

mission to continue as a candidate for the degree of Bachelor of Chemistry, even

though he has passed twelve (^) hours or more in the (^) preceding term. In (^) general, a scholastic record which does not show the (^) completion of at least twelve hours a term of the prescribed studies and a (^) grade of C or better in at least half of the

hours in Chemistry, will not be considered satisfactory.

Students in the Courses in Chemistry who receive a grade of "E" may remove

it by examination or other requirement set by the Department.

The degree of Bachelor of Chemistry, granted upon completion

of the four-year course of study just outlined, has a significance that

is in some respects unique, and, in so far as a degree may do so,

represents a distinctive type of training which its holders have under-

i

department of chemistry 1 1

Choice of Electives

Although the Courses in Chemistry and in Chemical Engineering

are rather highly specialized, they include a sufficiently large portion

of electives to enable the student to broaden his education by taking

courses in Literature, Public Speaking, Education, Psychology,

Philosophy, History, Economics, and^ other^ humanistic^ studies, or

to pursue intensive study in pure or applied science.

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^ a^ more^ 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.

GRADUATE (^) WORK IN CHEMISTRY

In any of the possible careers mentioned above, the scientific and

economic position of a chemist is greatly advanced by post-graduate

training. In research or plant work the holders of advanced degrees

are given preferment, while for teaching positions in institutions of

collegiate rank the doctor's degree is usually prerequisite. In order

that this degree may have a uniform significance, graduates of other

universities are required to present the substantial equivalent of the

chemical training included in the Courses in Chemistry, (see p. 7)

or to complete this during their graduate study at Cornell. Such

prerequisite courses should be taken during the first half of the

candidate's period of (^) residence, and together with the minor (^) subjects,

should give him a sound foundation for the major research problem

which will occupy the greater part of his last two years of residence.

REQUIREMENTS FOR GRADUATE STUDY

The Announcement of the Graduate School gives information re

garding the^ general^ requirements^ for^ admission^ to^ the^ Graduate

School, and^ for^ study toward^ advanced^ degrees; the^ following para

graphs are to be considered as supplementing but in no way super

seding these^ requirements.

Entering students^ must^ consult^ the^ chairman^ of^ the^ Graduate

Scholarship Committee^ of^ the^ Department^ of^ Chemistry,^ before

registering.

All graduate students in chemistry are required to register at the

Record Office of the Department of Chemistry, on the registration

days at the beginning of each term of residence, and to file at this

office, as^ well^ as^ at^ the^ office^ of^ the^ Graduate^ School,^ all^ records^ of

changes in registration, or in major and minor subjects, of completion

of language requirements, and of the passing of qualifying or general

examinations.

Graduate students are expected to take the examinations in all

courses taken in their major and minor fields of Chemistry.

MAJOR IN CHEMISTRY

Entrance Requirements

Candidates for the^ degree^ of^ Master^ of^ Arts, Master^ of^ Science, or^ Doctor^ of

Philosophy, with^ major^ in^ Chemistry will^ be^ required^ to^ offer^ for^ admission^ the

equivalent of Introductory Inorganic^ Chemistry 101 and^ 105; Qualitative^ Analy

sis 205 and 206, or^ 210; Quantitative^ Analysis^220 and^ 221, or^ 225; Introductory

Organic Chemistry 305, and^310 (one^ term); Introductory Physical^ Chemistry

405, and^410 (one^ term);^ they^ must^ also^ present^ the^ equivalent^ of^ two^ units^ of

German.

Candidates for the degree of Master of Chemistry must present the full equiv

alent of the^ requirements^ for^ the^ degree^ of^ Bachelor^ of^ Chemistry at^ Cornell

University. Minors

For a^ Master's^ degree^ one,^ and^ for^ a^ Doctor's^ degree^ two^ minor^ subjects,

chosen from^ the^ Divisions^ of^ the^ Department,^ or^ from^ other^ Departments,^ are^ re-

[13]

14 CORNELL^ UNIVERSITY

quired. The candidate is expected to acquire a general knowledge of the funda

mental topics (subjects, achievements) in the field of each Minor and an acquaint

ance with the history of the chief discoveries and generalizations in that field.

The candidate is at liberty to secure this information by lectures, by laboratory

courses or by reading, as he may prefer, except that the Member of the Staff in

charge of the Minor (^) may require the successful completion of lecture and labora

tory courses^ amounting^ to^ not^ more^ than^ six^ credit^ hours^ in^ all.

If the candidate has acquired the above general knowledge by courses taken

before entering upon his graduate work in this Department, he will be assigned

advanced reading in the field of the Minor as a means of fulfilling its requirement.

DOCTOR OF PHILOSOPHY

Attention is called to the fact that the additional year of residence required for

either the degree of Master of Chemistry or for that of Chemical Engineer at

Cornell University may, upon recommendation of the student's special com

mittee, be^ accepted^ as^ satisfying one^ year^ of^ the^ residence^ requirement^ for^ the

degree of Doctor of^ Philosophy with^ major^ subject^ in^ Chemistry.

Candidates for the degree of Doctor of Philosophy with major in Chemistry

must have completed, before the beginning of the last year of residence, the

equivalent of Advanced Quantitative Analysis (^) 230, Gas and Fuel Analysis (^) 250,

Introductory Physical^ Chemistry^ Laboratory^310 (second^ term),^ Introductory

Chemical Spectroscopy 505, and Introductory Chemical Microscopy 530.

Every candidate^ for^ the^ Doctor's^ degree^ is^ required^ to^ pass^ a^ Qualifying^ Exami

nation before he is allowed to begin^ actual experimental work on his thesis prob

lem. This examination will comprise tests in^ the following four Divisions of

Chemistry: (A) Inorganic and General; (B) Analytical; (C) Organic, and (D)

Physical. The individual (^) tests, each (^) consisting of a written examination (^) covering

a period of two or three hours, will be given in succession at intervals of one week.

One such Qualifying Examination is given at the beginning of each regular

term, and^ at^ the^ end^ of^ the^ second^ regular^ term^ of^ the^ University year, on^ days

set by the Committee on Qualifying Examinations. The candidate should present

himself for the Qualifying Examination not later than the beginning of the term

in which he expects to begin actual laboratory work on his thesis problem. In the

light of the candidate's achievement in this (^) examination, his Special Committee may further^ examine^ his^ qualifications^ for^ graduate^ study.

Failure of the candidate to pass any one of the four tests with a minimum grade

of (^60) will entail repetition of that particular (^) test; failure in this second (^) trial, or failure to pass two or more of the (^) tests with (^) a minimum grade of 60 will necessitate

repetition of the entire Qualifying Examination. Any candidate who fails to pass

all four parts of the Qualifying Examination on this final trial will not be allowed

to complete the requirements for the degree of (^) Doctor of Philosophy.

After the candidate has passed the Qualifying Examination, and has com

pleted his minor (^) subjects, he will be required to pass a general (^) examination, both written and (^) oral, on his major (^) and minor subjects. Upon recommendation of the

candidate's Special Committee, this examination may be taken toward the end of

the term (^) preceding his last year of (^) residence. This procedure makes it possible for the candidate to devote his last year of (^) residence to uninterrupted research on his thesis. At the close of his period of (^) residence, and after the acceptance of his thesis the candidate will be required to pass a final (^) oral examination on the thesis and on related subjects. As an alternative (^) procedure, the general examination on major and minor subjects and on the thesis (^) may be taken after the acceptance of the thesis.

MINOR IN CHEMISTRY, MAJOR OUTSIDE OF CHEMISTRY

The following courses, or their equivalent, are prerequisite: Introductory Inor

ganic Chemistry 101 and 105. Qualitative Analysis 210, Quantitative Analysis 225.

The (^) candidate shall (^) have such a (^) knowledge of the minor subject as could be

acquired by six credit hours of work^ in^ the^ field.
