Note 65 — {95} CHAP. V.
Reading edition
As seen on page 153, the latitude given for this place is 2° 32' too far north. Almost any quadrant, however bad, would permit of taking an observation closer than this; but as the error is approximately two and a half degrees, his mistake in observing the double altitude would be five degrees, and if he took an observation at all it is possible that this error was in making the calculations or in transcribing, rather than in taking, the observation.
