The object of the greatcft impchance to the fafcty of navigation is, to fix with precifioA the latitudes and lotigitudes of the places where he may land, and of thofe within fight of which he may pafs. With this view he will recommend to the aftronomer employed on board each frigate, to obfet\*e with the greateft exadnefs the movement of the time-keepers, and take advantage of every favourable circumftance for verifying, on ihorc, whether they have kept good daring the run, and to confirm by obfervation the change which m^y have happened in their daily move- ment, in order to keep an account of the change, fo as to determine, with greater precifion, the longitude of tlic iilands, the capes, or other re- markable points, which he may have obferved and laid down iji the interval of the two veri- fications. As often as the flate of the fky will permit him, he will order lunar obfervations to be taken, with the intlruments for that purpofe, to detcimine the longitude of the Ihip, and to compare it \\ith that which the time-keeper.^ indicate â i.
