Concise rules are given, with a variety of examples in every part of common navigation ; also, a new scientific, and very short method of correcting the dead reckoning ; with rules for keeping a complete reckoning at sea, applied to practice, and exemplified in three separate journals, in which may be seen all the varieties which can probably happen in a ship’s reckoning
