salts, and distribution between phases. The second term is deyoted<br />
to exact qualitative analysis, where these principles and<br />
those relating to oxidation and reduction are further applied to<br />
solutions; and the third term is given to the highly important<br />
field <strong>of</strong> chemical reactions between gases and between gases and<br />
solids, which is <strong>of</strong>ten neglected in elementary instruction.<br />
The second-year work in chemistry, which is taken by all students<br />
in the Course in Science, consists on the laboratory side<br />
<strong>of</strong> gravimetric, advanced qualitative, and electrometric analysis;<br />
but the class work is largely devoted to the discussion <strong>of</strong> the<br />
principles relating to mass-action, the ionic theory, oxidation,<br />
and the periodic law. In the second and third terms, and also<br />
in the subjects <strong>of</strong> physical and organic chemistry taken in the<br />
later years, the abler students, after a few weeks <strong>of</strong> introductory<br />
work, undertake minor researches in place <strong>of</strong> the regular work..<br />
The chcmical subjects <strong>of</strong> the junior and senior year consist<br />
<strong>of</strong> courses in physical, advanced inorganic, organic, and applied<br />
chemistry. The junior and senior courses in physical chemistry,<br />
here known as "Chemical Principles," are .not descriptive courses<br />
<strong>of</strong> the usual type; but from beginning to end are presented as a<br />
series <strong>of</strong> problems to be solved by the student. Also in the subjects<br />
<strong>of</strong> organic and applied chemistry problems are a feature.<br />
The supervision <strong>of</strong> the research work <strong>of</strong> graduate students is<br />
distributed among the whole staff <strong>of</strong> the Division <strong>of</strong> Chemistry.<br />
Each staff member takes charge <strong>of</strong> only three to five students<br />
who desire to work in his special field, so that each student re<br />
ceives a large amount <strong>of</strong> attention. Thus in physical chemistry<br />
the lines <strong>of</strong> research now being actively pursued by graduate<br />
students in cooperation with the staff are: equilibria and freeenergies<br />
at high temperatures; reduction-potentials in solution,<br />
especially <strong>of</strong> the rarer elements; the rates <strong>of</strong> homogeneous gas<br />
reactions; the photochemistry <strong>of</strong> reactions; band spectra in their<br />
chemical relations; crystal and molecular structure determined by<br />
X-rays; and the absorption <strong>of</strong> X-rays in its chemical relations.
