“ The second set supposes the Sun to be in the 10th degree of Leo, his altitude to be 56°, and his declination 18°; the difference, viz. 38°, is the complement of the latitude. Either set of readings suits the sense, but the one in the text agrees best with the former latitude, viz. 51°. 50′.37. After there, C inserts 38 grees, þat is; and omits the words of the pole, 51 degrees and 50 minutes. But this is a mere repetition of the 'height of the Equinoctial,' and is obviously wrong. ”
