Three bearings of the Friar’s Hood were also taken on the 
10th of September with an azimuth compass : one when we 
were nearly in the latitude, and another when in the longitude 
of the Hood. The same care was taken in finding the dis- 
tances, &c. ; and the latitude of the Hood was found to be 
7° 2 9 / 35° N. ; longitude 8i° 3 6' 3"^ E. 
It will no doubt be concluded, that where so much attention 
was paid to have the correct bearings and distances, that the 
meridianal observation for the latitude, and the altitudes for 
the longitude, were taken with a sextant : — this was the case ; 
and two sets of the latter were always observed. 
About the time the earliest of the observations mentioned 
in my former paper were taken, three correspondent eclipses 
of the satellites of Jupiter had been observed at Canton, by

allowing Bombay to be in 72 0 54 43", as deduced in my former paper, the longitude 
of Point de Galle will be 8o° 17' 13" east.
