Mr. Bowditch on the transit of Venus, June 3, 1769. 291 
actions of the Philosophical Society held at Philadelphia. The times 
of conjunction calculated at these places from the mean of the obser- 
vations, and reduced to the meridian of the State House in Philadel- 
phia, are as follows.

The mean of these six observations gives the apparent time of 
conjunction at Philadelphia 5. 4’ 8’-7, which subtracted from 10/, 4’

The transit was observed at Baskenridge, New Jersey, in the lati- 
tude of 40° 40’ N, by the Earl of Sterling, as follows.

The mean of these observations makes the conjunction at 54. 6’ 
$66 apparent time, which subtracted from 10/. 4 49"*7 gives the 
longitude of Baskenridge 4. 58’ 13”*1 W from Greenwich. 
At Quebee, in the latitude of 46° 47’ 17” N, and 10°4 in time W 
from the Castle of St. Lewis, the first contact was observed by Mr. 
Hollond at 2h. 30'8"3 apparent time. The parallax in longitude was 
— 10’-236, in latitude +8’*837, whence the apparent time of con- 
junction was 5, 21' 176, and the longitude of the Castle of St. Lewis 
4h. 43° 21-7, At the Island of Coudre}'in the latitude of 47° 16’ 30"

served by Mr. Wright, at 24. 50’ 50” apparent time. The parallax 
in longitude was — 11-249, in latitude 9-208. . ‘Whence the appar-
