4° Illinois Industrial University. 3. Illustrated experiments once 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. Higher physical experiments by advanced classes, consisting either of researches, or of reviews of careful and elaborate experiments previously worked up by others. The department of Physics is provided with illustrative apparatus for use in the lecture-room, and with an extensive Physical Laboratory. The collection of instruments 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 large number of pieces prepared at the mechanical shops of the University. It includes, also, Browning's electric lamp; and from Eliot Bros., London, resistance coils, galvanometers, etc., for higher researches in electricity. DRAWING. Projection Drawing.—-Use of instruments in applying the elements of descriptive geometry; use of water colors; isometrical drawing; shades and shadows; perspective; drawing of machines, bridges, roofs, etc., finished by line shading, tints, and colors. Free Hand Drawing.—Outline sketches; drawing from casts; sketches of machines, etc. Lettering.—Plain and ornamented alphabets; titles and title-pages; round and stump writing. Descriptive Geometry.—Problems on the point, right-line and plane; warped surface; perspective; shades and shadows; practical problems. APPLIED MATHEMATICS. Analytical Mechanics.—Polygon of forces; equations of equilibrium of moments; center of gravity; moment of inertia; acceleration, work, momentum, impact; motion of free particles; central forces; constrained motion. Strength of Materials.—Elasticity; safe limits; shearing stress; flexure and strength of beams and columns; practical formulas. Hydraulics.—Amount and center of pressure upon submerged surfaces; flow of liquids through orifices, weirs, pipes, and channels; distribution of water in cities. Forms and arrangement of orifices for fountains.
