NEAR FORT ST. GEORGE. 521 



means the zenith distances applied to it will give results 

 consistent both with the observations at Greenwich^ and 

 at Madras, and thus form a link by which the two ze- 

 niths may hereafter be connected. 



20. For this reason, in computing the Xth column 

 in Table III. I have adopted the following process :

21. It is greatly to be regretted that there are no 

 instruments in the Madras Observatory, wherewith to 

 take accurately great zenith distances ; for correspond- 

 ing observations of stars near the zenith of Greenwich 

 and of Paris, would have afforded powerful means for 

 correcting, after the same manner, the declinations of 

 all stars m that extensive space of the heavens which 

 divides the two Observatories.

22. It is a fact deserving of notice, that the medium
