an improvement in the mftrument with which to purlue fuch 
obfervations. 
My defign, as was hinted in that Paper,, was to afceitam, as 
well as I was able, the right afcenfions and declinations of the 
ftars I had laid down ; by obferving their meridian pafages and 
meridian altitudes , where that could be done with fuch fmall 
inftruments as mine ; as alfo by their comparative paff'ages 
through the field of an equatorial telefcope furnifhed with a
