Organic Chemistry.—Lectures and recitations, three hours weekly;
laboratory work four hours weekly, during the fall and winter terms of the
first year. This course includes the systematic study of organic chemistry
or the chemistry of the compounds of carbon, with special reference
to substances of importance in their relation to medicine. The
object of this course of study is to familiarize the student with the
more important organic compounds and with the methods at present
employed in chemical synthesis and to lay the foundation for subsequent
work in physiological chemistry, pharmacology, etc., etc.

A record of seventy per cent. on this course is required for admission
to physiological chemistry.

Physiological Chemistry.—Three lectures, three recitations and nine
hours of laboratory work weekly during the spring term of the first year.
This course has for its object to afford instruction in the fundamentals
of physiological chemistry, especially the chemical structure, properties,
and reactions of the more important compounds with which the
student must deal in his subsequent studies of physiology. The laboratory

work, for which ample facilities are provided, consists of the
thorough study of the properties of the carbohydrates, fats, soaps,
fatty acids, and proteins and of the more important members of each
of these groups; the composition of blood, milk, muscle, pancreas,
and other organs; the action of the more important digestive enzymes
and of the bile; and the chemistry of the urine. Accurate quantitative
determinations are required of urea (Folin), total nitrogen (Kjeldahl),
uric acid (Hopkins-Folin), ammonia (Folin), sugar (Fehling and
Benedict), and kreatinin (Folin). Other processes of quantitative
analysis, such as the Soxhlet method of fat determination and the
silver nitrate method of determining the total purins, are either demonstrated
or their essential manipulations carried out by the student
himself. The exceptional preparation of students not only in general
but also in organic chemistry makes it possible to acquire in this
course not only a clear understanding of the problems of physiological
chemistry but also skill in the use of the fundamental qualitative
and quantitative methods.

A grade of seventy per cent. on this course is required for admission
to Physiology.
