Scientific Instruments 1500-1900: An Introduction, by Gerard L'e Turner. 142 Pages. Clothbound. This extraordinary new book fills a long time void in the literature of tools and technology. In this one volume, author Gerard L'e Turner covers the basics and much more about the precision instruments of every principal profession. Arranged topically by the trade or profession in which the instruments were used, the author describes the need for the specific instruments, their historical development and variations, and includes spectacular photographs of instruments from the great museums and collections from Britain, Europe and the United States. Covered are astronomy, surveying, optical, medical, navigational and philosophical instruments. A chapter on calculators and measuring instruments is particularly well done. The instruments featured, particularly those in the color plates are alone worth the price of this great new book. Highly recommended. UNAVAILABLE (BK-0289)
