Latitudes and Longitudes of some remarkable Places, not contained in the preceding Tables. St. Nicholas's or Drake's Island, in Plymouth Sound. The bearing of Kit Hill, from the meridian of Butterton, is 67° 12′ 12′′, and the angle between it and the flagstaff on Drake's Island, 41° 40′ 8′′; therefore, the bearing of the latter from the meridian is 71° 7′ 40′′; consequently, its distance from the meridian is 60531 feet, and from the perpendicular 20692 feet, which respectively subtend 9′ 53′′6, and 3′ 24′′,5. These, with the latitude and longitude of Butterton, 50° 24′ 46′′,3 and 3° 52′ 47′′,5, give 50° 21' 21",1 for the latitude, and 4° 8' 17",9 for the longitude, of the flagstaff on Drake's Island. The latitude and longitude of this spot was determined by Mr. BAYLEY, in the year 1792. The observations for the former were as follows: ditto. α a Aquilæ. a Ophiuchi. 50 21 55 o's LL. The mean of these is 50°21′28′′,5. The place chosen by Mr. BAYLEY, as I have been lately informed, was a few feet northward of the staff; therefore, 7′′,4 may be taken for the true difference between our determinations. The longitude of Mr. BAYLEY'S station, found by the moon's transit, was 4° 18′ 52"; but the longitude deduced from the recent operations, is 4° 8'17",9; there is, therefore, a difference of 10' 34",1 between the two determinations. |
