290 Mr, Bowditch on the transit of Venus, June 3, 1769. 
vation was 5h. 20’ 8’*7. Professor Williams observed the same con. 
tact at Newbury in latitude 42° 48’ N, and by Hollond’s survey” 
63 seconds in time E from my house in Salem, or 593 seconds E 
from Cambridge, at 24. 48’ 44” apparent time. The parallax in lon- 
gitude was then — 11'°757, in latitude + 7643, whence the con- 
junction at Newbury was at 5A. 21’ 28’°0, corresponding to 5h. 20° 
28”°5 apparent time at Cambridge. The mean of this and the former 
result is 54. 20’ 18"°6, which subtracted from the time of conjunction 
at Greenwich 104, 4’ 49-7, gives the longitude of Cambridge by this 
observation 4h. 44’ 311. e 
At Providence in latitude 41° 50’ 41”, the transit was observed by 
Messrs. West and Brown. The first contact was not well observed, 
but the second contact was at 2h. 46’ 35” apparent time. The paral- 
lax in longitude was — 11’*762, in latitude +7’-282, Hence the 
conjunction was at 54. 19’ 12”7 apparent time, which subtracted 
from the time of conjunction at Greenwich 10h, 4’ 497 gives the 
longitude of Providence by this observation 4h. 45’ 37-0, By the 
eclipse of Oct. 27, 1780 it was 4h. 45’ 38’°6. The mean gives the 
longitude of Providence 44. 45’ 37"-8, and by subtracting 188 we 
have the longitude of Goat Island, Newport, 44. 45’ 190 W from 
At the State House square in Philadelphia, in the latitude of 39° 
57 10”, the transit was observed by Messrs. Shippen, Williamson, 
Prior, Ewing, Pearson, and Thompson, At Norriton in the latitude 
of 40° 9' 56", and by an accurate terrestrial measurement 52” in time 
W from Philadelphia, the transit was observed by Messrs. Smith, 
ams and Rittenhouse. At Lewistown in the latitude of 38° 46’ 38" 
and 1*"4 in time E from Philadelphia, as determined by an accurate 
survey, the — was observed by Messrs. Biddle and Bayley. The
