• Improvements in navigation, and philosophy. Which contains, I. An easy method of finding the longitude at sea, which will be easily practicable there, and which will determine the said Longitude within ten or fifteen Minutes at most: Also a more easy Method of finding the Latitude, and that by the same Instrument that finds the Longitude, and to the same Pitch of Exactness, and without any Regard to the Sun's Shining, or the Sun's Declination, or any Calculation; but if the Horizon be clear, Sailers may see the true Number of the Degrees and Minutes of both the Longitude and Latitude of the Place they are in, upon the Instrument before their Eyes. II. In the next place, here is an endeavour, to amend some things, in the present account of the system, and the principal Phaenomena of this visible World; containing great Improvements in Philosophy.
