The above observations for longitude were made at my Bunga- 
low, in Lat. 25° 31' 21" N., bearing N. 50° W., and exactly 4J 
furlongs, or 990 yards, distant from the centre of the village of 
Keitch. If, therefore, 26" is added for the meridian of the vil- 
lage, the longitude of Keitch will be 79° 29' 39" E., thus ob- 
tained from astronomical observation ; and the result of the tri- 
gonometrical operations brings it out 79° 29' 40" E., differing 
only one second. 
I could subjoin many other observations for longitude, which 
approximate very closely to the results obtained by triangula- 
tion ; but, as the position of every place mentioned in the above 
Table was determined by the same series of operations, it would 
be encumbering your valuable pages to no useful purpose, par- 
ticularly as the results of the protraction already given opposite 
to each, are undoubtedly more accurate.
