Altitude tables computed for intervals of four minutes between the parallels of latitude 24° and 60° and parallels of declination 24° and 60° : designed for the determination of the position line at all hour angles without logarithmic computation

Altitude tables computed for intervals of four minutes between the parallels of latitude 31° and 60° and parallels of declination 0° and 24°: designed for the determination of the position line at all hour angles without logarithmic computation

Captain Sumner's method of finding a ship's position at sea from having given one altitude of the sun and the time at Greenwich improved and simplified: including a new, short, and easy method of finding the time at the ship, and thence the longitude by chronometer, also a method of finding both latitude and longitude by double altitudes, and methods of finding the latitude by double altitudes and simultaneous altitudes

Altitude tables computed for intervals of four minutes between the parallels of latitude 31° and 60° and parallels of declination 0° and 24°. Second edition: designed for the determination of the position line at all hour angles without logarithmic computation
