Abstract
THESE tables were originally prepared in 1941 by the Nautios Almanac Office, at the request of the War Office, for use in survey calculations. In 1945 they were reprinted, but the present issue, dated 1947 is the first one to become available to the general public. They contain natural values only, and are intended to replace similar tables, published in 1924 Part 2 of the "Manual of Artillery Survey"), which provided logarithmic values of the same four functions. It should be emphasized that they are primarily designed for use with calculating machines and are of no great practical value unless such a machine is available.
