An Account of Astronomical Observation's 

 taken at the Honourable Company's Observa- 

 tory, near Fort St. George in the East Indies, in the 

 Years I8O6 arid 3 807. To which are added some 

 Remarks p« Me Declination of certain St ar^ 

 dftdof the Sun, when near the Zenith of that Place. 



BY CAPTAIN JOHN WARREN, 

 OF H. M. 33d REGIMENT OF FOOT. 



^' JVIajor Lambton having sent his zenith sector to 

 the Madras Observatory in September ! §06, I began 

 early in the ensuing month the observations which 

 form the subject of the present paper. As an account 

 of this instrument has aheady been given to the public, 

 in a paper written by that gentleman, and published 

 in the 8th volume of the Asiatic Researches, I shall 

 only observe here that it came to me in high order, 

 and that I observed constantly with it from October 

 180(5 to June I8O7, without perceiving any material 

 change in its powers or mode of performing. 



2. In undertaking a series of observations of zenith 

 distances, I had in view to establish permanendy the 

 latitude of the Madras Observatory, on which there 

 seemed still to be a doubt of several seconds, and also 

 to verify the declination of several stars near the zenith, 

 when used for obtaining the latitudes of places, disa- 

 greed in their results. 



3. This laborious and dry enquiry, I am aware can 

 afford but little entertainment to the generality of read-
