Abstract
THE position-line method in navigation was first introduced by Capt. Sumner; it has greatly grown in favour, since it exhibits in a convenient manner all the information that a single observation of altitude is capable of affording. There have been a large number of nautical tables published with the idea of simplifying the application of the method to determine the position-line of the ship. The “Altitude Tables” of the Rev. F. Ball give the altitude for every degree of latitude, declination, and hour-angle. Other tables by Aquino are in wide use in America. Mr. Herbert Bell proposed some useful modifications of the plan of the latter in a paper in M.N.R.A.S., vol. Ixxx., p. 72.
