Mathematical tables: Containing the logarithms of numbers; logarithmic sines, tangents, and secants, to seven decimal places. And a traverse table. To which are prefixed, logarithmical arithmetic, and plane trigonometry, in which the order of the cases is that observed in the appendix to Dr. Simson's Euclid. Also examples in practical geometry, adapted to the propositions in Dr. Gregory's treatise, wherein the help of the following tables is needed. The whole being calculated either to accompany the above books, or to be studied separately. By J. Brown, mathematician.
