MICROSCOPES. IN the Practical Courses of Biology, Physiology, Pathology, and Bacteriology, students may use the microscopes provided by the University, for the use of which a charge is made. But they are strongly recommended to purchase for themselves microscopes of an approved pattern, and to use them throughout their course. A microscope suitable for bacteriological work, and for the proper clinical examination of the blood, is now an essential part of the equipment of every medical man. It is, moreover, a great advantage for the student to use his own microscope during his undergraduate course, as he thus becomes familiar with its working, and is in a better position to profit by its use in after years. With the exercise of a little care the efficiency of a good microscope will not thereby be impaired. Excellent microscopes are supplied by the English firms, Swift, Beck, Ross, and Watson; by the American firm, Bausch and Lomb; and by the Continental firms, Zeiss, Reichert, and Leitz. The student is particularly warned against the purchase of an inferior type of microscope which will not be approved by the Professors, and it is hardly necessary to point out that not every microscope made by the above-named firms is of a type that can be approved. Students are, therefore, invited to consult the Professors before making any purchase. The following types of microscope, procurable in Sydney from agents of the manufacturers, are recommended as adequate, and at the same time moderate in price. With the accessories given they are adapted for the Practical Biology and the Practical Physiology:- W. Watson & Sons' Edinburgh Student's Microscope, Stand "B," with and inch objectives, Nos. 2 and 4 eye-pieces, double nose-piece, and illuminating apparatus. Price, £10 12s. 6d Or W. Watson & Sons' Stand "C," similar to "B," but with better illuminating apparatus, etc. £12 17s. 6d. Bausch & Lomb's Microscope BB5, with double nose-piece, Abbé condenser, No. 3 eye-piece, and 3 and 6 objectives. Price, £12. Leitz's No. 2A, with double nose-piece and Abbé condenser, £10 9s. Reichert's Stand III., with Abbé condenser, objectives 3 and 7 of best series, ocular 3, double nose-piece. About £9. For the Practical Pathology and Bacteriology a higher power objective is required-preferably a homogeneous immersion, which costs about £5 10s. DEPARTMENT OF GEOLOGY AND MINERALOGY. Students may use their own microscopes in the demonstrations on Petrology, provided they are of a pattern approved by the demonstrator, to whom they must be shown beforehand. Advice will always be willingly given to any students desiring to purchase a microscope. The microscopes in use for demonstrations are the following: (1) Student's Petrological Microscope, with centering stage or nose-piece, revolving double nose-piece, and two objectives, both of highest numerical aperture. The latter should be 1 inch and inch, or 1 inch and inch. The best combination is of three or triple nose-piece, 1 inch, inch, and inch. Price in London, about £14, including two objectives. (2) The Dick Petrological Microscope, with revolving nosepiece and objectives as in (1). Price in London, about £23, including two objectives. The above microscopes are made by Messrs. James Swift and Son, 81 Tottenham Court Road, London, W. |
