4 24 Mr . Gold ingham on the geographical situation of 
I shall now proceed to give some information respecting 
the latitude of the Observatory. The height of the pale at 
Madras being only 13 degrees, the method by circumpolar 
stars cannot be used ; and the latitude has been found by 
meridianal observations of the sun and stars north and south 
of the zenith, taken with the sextant, a circular instrument of 
18 inches diameter by Troughton, and the zenith sector used 
in Colonel Lambton’s Survey. 
The results were as follow : 
Latitude of the Madras Observatory by obser- o # 
vations of stars with the sextant, - - 13 4 8,606 
With the circular instrument, stars north and 
south of the zenith, - 13 0 4' 11", 894

During my absence in England, I find the zenith sector 
was again brought to the Observatory, there being some 
doubt, as it would seem, of the correctness of the foregoing
