Short, but plain and easy, directions for the use of Hadley's quadrant : In which care is taken not to encumber it with more than is necessary, or needless encomiums, but to render it useful to the learner; it being now so well known to the world as not to want an advocate in its praise. To which is added, a description of the vernier scale, commonly call'd nonius's division.

The Construction and use of the sea quadrant, commonly called Hadley's quadrant : Containing such directions, as are necessary to render the use of this noble instrument both easy and certain, particularly with respect to the back observation, which has been hitherto neglected for want of proper instructions. To which is added, an introduction, explaining the theory of the instrument in a plain and familiar manner, with correct tables of the sun's declination, which being calculated for four years are thereby rendered perpetual.
