PROFESSOR R. E. ROGERS.

This subject included in the medical as well as the general academic
course, and forming a department of the School of Chemistry
and Materia Medica, may be studied separately, or in conjunction
with the latter.

The Lectures, which are delivered twice a week throughout the
session, embrace a very full illustration of all the topics of theoretical
or practical importance in the science, and in its applications
to Mineralogy, Geology, the Chemical Arts, Agriculture and Physiology.

Beginning with an account of the phenomena and laws of Heat,
Light, and Electricity, Mechanical and Voltaic, the course next
takes up the doctrines of chemical reaction, presenting a full and
minute view of the principles of definite combination, with their
hypothetical expression in the form of the atomic theory, and illustrating
these doctrines by numerous experiments and drawings.
To this succeeds Pneumatic Chemistry, in which are discussed the
preparation, properties and applications of the various gaseous
bodies and their compounds.

This is followed by the detailed account of the metals, their oxides,
chlorides, and other compounds, connecting with each metal

the chemical history of its important salts. A resumè is now given,
accompanied by illustrations of the various processes of analysis
deduced from the preceding facts.

Organic Chemistry is next taken up, embracing an account of
all the more important organic acids, alkaloids and neutral principles,
together with a view of the alcoholic, acetous and other
fermentations; the Chemistry of nutrition, growth, respiration, &c.,
in the vegetable and animal economy, and that of soils and manures
as connected with agriculture.

In connexion with these topics, minute experimental illustrations
are given of all the valuable processes for detecting poisons
and for counteracting their effects. The more important operations
of analysis, as applied to ores, marls, &c., are also described
and exemplified.

Throughout the course, use is continually made of ample diagrams
illustrating the chemical reactions, according to the method
of equivalents; and the bearings of the recent generalizations of
Dumas, Liebig, Kane, Graham and others, are particularly referred
to.
