The MICROSCOPES manufactured by this Company have now been before the publie for several years, and during that time have given universal satisfaction. They are recommended by some of our leading microscopists, and are in use in many of our highest institutions of learning. They are constructed with several improvements not to be found in the instruments of other makers, and the patents for which this company exclusively own. The principal one of these is the FINE ADJUSTMENT, Amateur's Handbook which is very sensitive, has no lateral swing whatever, nor any lost motion, and, having no friction, is not liable to deterioration. THE BAUSCH & LOMB OPTICAL COMPANY have also recently made several important improvements in the Object-Glasses manufactured by them, and they now invite the most rigid examination, and challenge direct comparison with similar products of other makers. The facilities at their disposal, and their improved system of manufacture, enable them to have each part of every instrument made with the greatest care, accuracy and perfection, increasing thereby its general efficiency. The above described Microscopes have recently received the Award of a SILVER MEDAL at the Universal Exposition of Paris, of the present year. Special attention is further called to the NEW STYLE OF OBJECTIVE, with glycerine adjustment for cover-correction, having many and important advantages over the old mode of adjustment, and of which this Company also own the exclusive right of manufacture.
