Modern Navigation

THIS is a valuable text-book on navigation at a very moderate price. Its small size and general handiness are a great feature compared with other works on the subject. The proofs throughout the book are graphically explained so far as possible, and are easily intelligible to people with a limited knowledge of mathematics; the figures and illustrations are good, numerous examples are given throughout, and the answers are tabulated at the end of the book. The extracts from the “Nautical Almanac” necessary for working any of the examples are also given.Modern Navigation.By W. Hall Pp. viii + 378. (London: W. B. Clive, 1904.) Price 6s. 6d.
