Part II, §23, l. 3.  The star A is shewn by the numbers to be the Pole-star, and is obviously the one to be observed in order to find the altitude of the Pole.  What the star F is, is of no consequence.  The numbers used in other copies are different, and much less satisfactory.  That the star A is the I'ole-star or some star near the pole in this `conclusion' is rendered probable also by the wording of the next `conclusion'; which extends the working of it to the case of any other star, provided it be a star that never sets.
