A history of the logarithmic slide rule and allied instruments ; and On the history of Gunter's scale and the slide rule during the seventeenth century

The slide rule, with its many variations, has been vital to mathematics and engineering since its invention in the 17th century. Interest in this field has grown dramatically and collectors can still find much material at affordable prices. Unfortunately there has been little information available except for manufacturers manuals and catalogs, making this reprint of Cajori's classic particularly valuable. Also included with this reprint of the 1910 edition is Cajori's extensive article On the History of Gunter's Scale and the Slide Rule during the 17th Century, published by the University of California in 1920, which sets forth his subsequent findings. There is also a helpful explanatory introduction by Dr. Robert K. Otnes, editor of the Journal of the Oughtred Society. 178 pages. Illustrated. 61/8" x 91/4". Hard cover.
