“‘ mont, latitude 43° 36’ N, as ascertained by Dr. Williams ; longi- 
“tude west from Greenwich [72° 58’ 15] as ascertained by Mr. Bow-

“ June 16, 1806.” Ina letter, which accompanied the preceding pa- ~ 
per, Mr. Page observed that his recollection of the meteor was pretty 
distinct, and that he was enabled to determine its situation by the posi- 
tion of certain known objects, 
Deductions from the preceding observations. 
The observations made at Wenham, combined in various ways 
with those at Rutland and Weston, by the methods given in the pre- 
ceding problems, furnish the results contained in Table 1, in which © 
the given quantities are marked with an asterisk. These quantities 
are varied a few degrees in the different examples, for the purpose of 
forming an estimate of the change in the calculated place of the me- 
teor, from any supposed error in the observations. In the two first 
€xamples are combined (by Problem 2) the azimuth and altitude ob- 
served at the first appearance of the meteor at Rutland, with various 
supposed altitudes at Wenham. The 3d. and 4th. examples are like 
the first and second, except in a small change in the altitude and azi- 
muth at Rutland. In tue 5th. and 6th. examples, the first azimuth 
and altitude observed at Wenham are combined (by Problem 1) with 
the azimuth at Weston, supposing it in the 5th. example to be north ; 
and in the 6th. N3°W. The 7th. and 8th. examples contain the re- 
sults from combining the same Wenham observation with the azimuth 
at Rutland, supposing it in the 7th. example to be N 170° 30’ W, and 
inthe 8th,N173°W. From the 9thto the 12th. examples, the same
