[[/margin]] Whereby it appears that if the Latitude of the place be known to the exactness of a degree only, the declination of the plane will hence be known to a second of a deg. in the year 1765 & for many years after. & I think to get a Meridian within a second of the truth is as near as can [[strikethrough]] possibly [[/strikethrough]] be wished, or even [[strikethrough]] obta [[/strikethrough]] possibly obtained by any method whatsoever. -- As the North pole Star [[strikethrough]] where [[/strikethrough]] moves bye the line very slow, One of a less Declination, or greater distance from the pole, would be more proper; therefore [[underline]] Capella [[/underline]] under the pole and a Star of the 3.[[superscript]] rd [[/superscript]] Mag. in Draco, about 0°..0'..0" γ of Long. & 85°. of North Lat. are more commodious, if not the best: Also [[underline]] Dubbe [[/underline]] in the great Bear, Upper pointer, [[strikethrough]] and [[/strikethrough]] Alioth, below the pole, and One of the 3.[[superscript]] rd [[/superscript]] Mag. in the left thigh of [[underline]] Cepheus [[/underline]], One of the 3 [[superscript]] d [[/superscript]] mag. in the Right shoulder of [[underline]] Cepheus [[/underline]], The heart of [[underline]] Cassiopeia [[/underline]] of the 3.[[superscript]] d [[/superscript]] Mag. ^ [[insertion]] above the pole,[[/insertion]] are likewise very proper.

[[/superscript]] Ascen. of the Star under the pole exceed that above the pole by [[strikethrough]] [[?]] [[/strikethrough]] ^ [[insertion]] more [[/insertion]] than 180°. the Declination is West: but if it exceeds it by ^[[insertion]] less [[/insertion]][[strikethrough]] [[?]] [[/strikethrough]] than 180.° the declin. is East. If the R[[superscript]] t. [[/superscript]] Ascen. of the Star under the pole be less than that above the pole by more than 180.° the declin. is E; but if by less than 180.° the declin. is W.

Transcription Notes:
Everything looked great, I just added a possible 4 to the Lat. 51N column in top table.
