Excerpt from Elementary Optics and Applications to Fire Control Instruments: Prepared Under the Director of the Chief of Ordnance, May, 1921The aim'in the preparation of this pamphlet has been to provide a handbook of applied Optics and optical instruments suitable for use as a textbook in the Army training schools, and for the information of the officers and men who use optical fire control apparatus.In the selection of material no attempt has been made to produce an exhaustive treatise. It has rather been the purpose to treat more fully those phases of the subject which are not dealt within the books ordinarily available, or which are particularly characteristic of. Fire control instruments, and to avoid the unnecessary duplication of material which is already accessible in elementary textbooks so far as is possible without the undue sacrifice of completeness.For the reader who desires more complete information, the follow ing books, all of which are available in English, are recommended.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
