Essay Method Determining Difference Longitude by Lowe Gavin (1 results)

First edition of this rare pamphlet, recorded in only three institutions on WorldCat. A rather enigmatic figure in the history of British astronomy, Lowe established an observatory at his home in Paradise Row, Islington. Writing out of concern about "erroneous or imperfect" methods currently circulating (p. 3), he describes a method based on "the observed increase of the Moon's right ascension in passing from the first to the second meridian, and the increase of the Sun's and Moon's right ascension in twelve hours' apparent time" (p. 3). Lowe (c.1743-1815) was known to his friends as "a gentleman eminently skilled in the mathematics and in the knowledge of theoretical and practical astronomy" (Firminger, p. 102). He patronized leading makers of astronomical instruments, housing a fine collection in Paradise Row. For example, he commissioned Edward Troughton to make the Troughton Transit Circle, later used to much affect by the British astronomer John Lee (1783-1866), after whom it is sometimes referred.
