INFORMATION FOR GRADUATE STUDENTS 163
filed by April 20 with the professor in charge and circulated among
the members of the examining committee. Likewise on this date, the
candidate must file and circulate a paper, prepared for publication in
form acceptable to his examining committee, embodying the results
of his research in whole or in part.
E. BIOLOGY
1. To be recommended for candidacy for the doctor's degree in
Biology a student must pass a comprehensive written examination
covering advanced work in the major and minor fields at least two
terms before the degree is to be conferred. A final oral examination
covering principally the work of the thesis will be held at least two
weeks before the degree is to be conferred.
2a. Animal Physiology. For a major in Animal Physiology, the
subjects in this field and other supplementary subjects of graduate
rank must be taken. If there is one minor, it must be taken in
Biology; if there are two minors, the second may be taken outside the
Division of Biology.
2b. Biochemistry. Either the Biology or the Chemistry Option
or its equivalent is prerequisite. In either case, examinations in
Chemical Principles and Organic Chemistry, set by the Division of
Chemistry, must be passed satisfactorily; and an examination on
Biochemistry (based on Bi. 7a, b) must also be passed. Later, more
advanced work (Bi. 110 and 102) will be required before the examination
for admission to candidacy is taken. At least one of the
minors must be in another department of the Division of Biology.
2c. Bio-organic Chemistry. For a major in Bio-organic Chemistry,
either the Biology or the Chemistry Option or its equivalent is
prerequisite. Those who take the Biology Option should indude
Ch. 46a, b (Organic Chemistry Laboratory) either as an undergraduate
or graduate subject. For graduate work in bio-organic
chemistry, the subjects Bi. 115 (Chemistry of Bio-organic Substances)
and Bi. 141 (Plant Chemistry) are both required. For the
minor some field of biology or chemistry should be chosen.
