coatings, starch, pulp, germs ami various tissues. Nothing has ever exceeded the beauty and fidelity of these artificial fruits and flowers. Besides these the university possesses extensive herbariums, collections of woods, seeds, grains, etc.; also large nurseries of forest and fruit trees. Orchards, gardens, small fruit plantations and ornamental grounds, a propagating house, and a large green house just added. A botanical garden and an extensive arboretum are in preparation. The department has also two large and powerful microscopes. ZOOLOGY, GEOLOGY, ETC.—Cabinets of insects, birds, reptiles, mammals, shells, skeletons, fossils, minerals, charts and plates are already collected and are rapidly increasing. A large double magic lantern, such as are manufactured for the English government army schools, has been procured 'from London, with a large number of slides to illustrate geology, natural history, astronomy, history, etc. AGEICTJLTUBE.—Besides the foregoing, nearly all of which serves to illustrate the sciences related to agriculture, the university farms, gardens, etc., embrace over a thousand acres of fine improved farming lands, on which large model barns are being erected, and for which several breeds of fine stock are to be purchased. To illustrate veterinary science, a veterinary stable is to be erected and papier •ntaclie models from Dr. Auzoux, of the_borse's mouth and teeth, show the successive changes with age. A dissected foot and ankle from the same nianufactor, beautifully illustrates the complicated structure of this part of the horse.

PRACTICAL MECHANICS AND MECHANICAL ENGIKT:EKING.—A mechanical

shop, occupying a two story building, is now established on the grounds of the University. In the upper story is the carpenter's shop. This shop is supplied with a circular-saw, jig-saw, morticing machine, and a set of work benches and vises for students, with all the necessary carpenter's and cabinet-maker's toolsThe lower story is devoted to the machine-shop, which is furnished with a boiler and steam engine of eight horse power; a machinist's " engine-lathe," and two hand-lathes, fitted up with chucks, drills, &c.; a wood-turning lathe ; a patternmaker's bench, with its complement of tools; a blacksmith shop; molding-sand, crucibles, &c, for making brass and other castings; several iron vises, and sundry other tools valuable in the machine-shop. The engine is of special design, being adapted to receive different sets of valve-gears, for the purpose of illustrating to the classes, in a working model, the different varieties of the steam engine. In the mechanical shop, models and apparatus are constantly being made by the students, with the assistance of the director of the shops, and added to the present set of valuable illustrative apparatus of the class-room. N. B.—Apparatus, of good quality, can be furnished for high schools and colleges. Orders are solicited.

PHYSICS AND NATURAL PHILOSOPHY.—This collection includes some of the

latest and most important improvements in the apparatus of physics and natural philosophy. The air pump is of the best form in use. It was made by the celebrated firm of E. S. Ritchie & Sons, of Boston, and cost $275. It has a rotary movement, combined with "Ritchie's patent action'' of the piston and valves. This final step in the perfection of the air pump furnishes the means for the nearest approach to an absolute vacuum that it is possible to make by mechanical means. The electrical machine is Ritchie's Patent Holtz Machine. This remarkable machine is of recent discovery, and for this reason is found in but few of the cabinets of older institutions of learning. It is distinguished for its wonderful power and great ease of action, rendering it suitable for performing many experiments, which, with the ordinary machine, were extremely difficult.
