Bi. 117. Quantitative Organic Microanalysi •• 20 units (0-20-0); .econd
term.
Laboratory practice in the methods of quantitative organic microanalysi. required
for structure determinations of organic compounds. Students must obtain permission
from the instructor before registering for this subject as the enrollment is necessarily
limited.
Instructor: Haagen-Smit.
Bi. 120. Experimental Embryology. 6 units (1-0-5).
Lectures and discussion of the problems of embryonic development, including
luch topics as growth of the ovary, breeding habits of animals, fertilization, cleavage,
organ formation, metamorphosis, regeneration, tissue culture, embryonic metabolism,
etc.
The subject may be taken for two consecutive years since the subject matter
will be duplicated only in alternate years.
Instructor: Tyler.
Bi. 121 a, b, c. Experimental Embryology Laboratory. Units to be decided
by student and instructor; given any term.
