Abstract

XLI. Account of the transit of Venus over the Sun's disk, as observed at Norriton, in the county of Philadelphia, and province of Pennsylvania, June 3, 1769. By William Smith, D.D. Provost of the College of Philadelphia; John Lukens, Esquire, Surveyor-General of Pennsylvania; David Rittenhouse, A.M. of Norriton; and John Sellers, Esquire, one of the representatives in assembly for Chester County; the committee appointed for that observation, by the American Philosophical Society, held at Philadelphia, for promoting useful knowledge. Communicated to the said Society, in behalf and by direction, of the Committee, by Doctor Smith; and to the Royal Society of London, by Nevil Maskelyne, B.D. Astronomer Royal. Gentlemen, Among the various public-spirited designs, that have engaged the attention of this Society since its first institution, none does them more honour than their early resolution to appoint Committees, from their own members, to make as many observations, in different places, of that rare phaenomenon, the transit of Venus over the Sun's disk, as they had any probability of being able to defray the expence of, either from their own funds, or the public assistance they expected.
