"An Auxiliary Range Corrector Scale for Infantry"

Here's more from the scan-o-rama. The author of this little booklet is Capt. H. E. Eames of the 18th Infantry, and the material is reprinted from the Infantry Journal of July-August 1915 by the Bausch & Lomb Optical Co. of Rochester, New York. Uploaded here are the cover and the first page of twelve. The inside title page adds this: Description of "Eames Scale" as applied to Bausch & Lomb Stereo Prism Binoculars. This may be the same Captain Eames who appears in bibliographies of military manuals as author of The Rifle in War (1905).
