Such are the befl obfcrvations of this kind, which I am able to lay before this honourable 
and learned Society. It gives me much concern to find that they differ fo widely from one an- 
other ; more efpecially as I am certain that I made them with all the care and circumfpeftion 
that I was capable of, and with an inftrument which leemed to me good of its kind. But I 
flatter myfelf it will be confidered, that, in making obfcrvations with this inftrument, there are 
two unavoidable fources of error, viz. in adjufting the card to the line on the fide of the com- 
pafs-box, and in making thefhadow of the thread to fall on the line of the index: I may 
likewife add a third error, which may be committed in reading of the vernier, as it only fub- 
divides to every 5' ; and if all thefe fhould happen to fall the fame way, their fum, I prefume, 
may be confiderable (when an inftrument of fo fmall a radius is ufed), in the hands of the 
moll fkilful obferver.
