Year: 1878 Language: english Author: Edmund McNevin Genre: Manual Publisher: A. L. Bancroft & Co. Format: PDF Quality: Scanned pages + text layer Pages count: 360 Description: This manual has been written by a twenty years experienced merchant marine master, and has been written for seamen, instead of scholars or scientists. It is clearly aimed to help the navigator to find quickly and accurately his position at sea in the simplest possible way, and by choiche avoids all other methods of determining latitude and longitude, either difficult or poorly accurate, such as lunar observations. Some useful and, for the time, innovative methods are given. The author calls out the student's special attention to the system of finding simultaneously latitude and longitude by double altitude, and to a leeway indicator (a diagram is given). For finding latitude by star altitudes refers to the American Ephemeris for the declination of the fixed stars instead of to the English tables, with the notation of the former. Content well detail topics.
