I observed the distances of [[sun symbol]] & [[symbol]] with my "Resolute" Sextant, except the 4th (A) which was with my [[underlined]] pocket [[/underlined]] sextant, [[underlined]] without any Index Errors. [[/underlined]]
The Error of the former, being -2[[feet symbol]] (subtraction - [[underlined]] 'On 33[[feet symbol]] - 30-^[[?]] off 29[[feet symbol - 30[[inch symbol]] [[/underlined]] = '2/4[[inch symbol]] = -2[[feet symbol]]) took the same (- 2[[feet symbol]]) out as follows:
84[[degree symbol]] = 28[[feet symbol]]-00[[inch symbol]]-2 = 84[[degree symbol]] -26[[feet symbol]]-00[[inch symbol]]
30-00-2 = 28-00
