Mr. Bowditch on the solar eclipse, Sept. 17, 1811. 273 
Observations at Portland, by the Rev. Mr. Nichols and others, 
Sept. 17, 1811. 
The beginning of the eclipse at Observatory Hill was Of. 57’ 32” 
apparent time, and at Mr. Nichols’ observatory one mile W from the 
former place OA. 57’ 34” mean Of. 57’ 33”. The end at those places 
was at 3h. 58’ 48”°7 and 3h, 59’00" mean 3/. 58’ 54’*3. The latitude 
of the place of observation nearly 43° 39’, reduced 43° 27’ 32”.

Hence the apparent time of conjunction was at 2h. 15'41"-5, which 
subtracted from Gf. 57’ 6’*1 leaves the longitude of Portland 44. 41 
24"6, which makes Observatory Hill in the longitude of 44, 41’ 22” 
W from Greenwich.

Hence the apparent time of conjunction was at 2h. 17° 23”*1, which 
subtracted from 6. 57’ 6”*1 leaves the longitude of Bowdoin College 
4h, 39' 43"°0 W from Greenwich. It will be seen in the addition to 
this memoir, that the end of the eclipse of the sun of June 16, 1806, 
made the longitude of this college 44. 39’ 37’"3.. The mean of these 
observations makes the longitude of that place 4A, 39’ 40" 1=69° 551" 
‘W from Greenwich.
