The advancement of the art of navigation in two parts, the first, shewing by a new canon of sines, tangents, and secants, how to resolve all cases of right-lined triangles, only by looking into the tables, without any calculation : particularly applied to all the three kinds of sailing : viz. [brace] by the plain-chart, by mercater's chart, by a great circle : and to the art of surveying : the second part shewing several observations for the better ordering the logline, and for the more exact and ready measuring, not only minutes, but seconds of time : with some new experiments for the more constant finding of a ship's way.
