reasoning; principles and methods of investigation. Practical applications of logic in the construction of argument, in the detection and answer of fallacies, and in the formation of habits of thinking and the common judgments of life. PHYsics. The department of physics is amply provided with illustrative apparatus for use in the lecture room, and an extensive Physical Laboratory has been instituted in the New Building. The laboratory is adjacent to the physical lecture room; connected by sliding doors so that the apparatus is convenient either for use in the lectures, or for the laboratory work. Instruction in physics embraces four kinds of 'work: 1. Recitation, four exercises a week in which a text-book is used as a guide. 2. Physical experiments one day each week, in which the student uses the instruments in testing the principles taught. 3. Illustrated experiments one evening each week in which the more costly apparatus is used before the whole class, in such experiments as are difficult to perform and which are most effective when prepared for an audience. 4. The higher physical experiments by advanced classes consisting either of researches, or of reviews of careful and elaborate experiments previously worked up by others. To prepare for the last named work, the student should have pursued Physical studies at least one term in the first thiee. The laboratory and the lecture room are in the first story above the chapel, and occupy the same amount of floor. The collection of instruments, costing over $5,000, embraces Acoustic apparatus from R. Koenig of Paris; apparatus for Heat and Molecular physics from J. Salleron of Paris; for Light, Optics and Electricity from Stoehrer of Leipsic, and Browning and Newton of London; Pneumatic and Electrical apparatus from E . S. Ritchie of Boston; and a number of pieces prepared at the Mechanical Shops of the University. During the past year have been added Browning's Electric Lamp, and from Elliott Bros. London, Resistance Coils, Galvanometers, etc., for higher researches in Electricity.

ASTRONOMY AND GEODESY.

Temporary arrangements have been made for Observatory Practice by the erection of a small observatory and the mounting of instruments of convenient size for students' use. DESCRIPTIVE ASTRONOMY is given by lectures with a text-book. The Equatorial Telescope is in constant use during the favorable weather. PRACTICAL A S TRONOMY is given by lectures and practical work with the Meridian Circle, Sextant, Theodolite, and Engineers' Transits adapted to Astronomical work and by Astronomical Calculations. GEODESY is given by lectures, practice and calculations. Messrs. Estel & Son of Munich, Germany have nearly completed a first-class Universal Instrument for the use of the Senior engineers, which will read to single seconds of altitude and azimuth bv four micrometer microscopes, and trigonometrical stations will be erected.
