Thus, on the 24th October, 1776, (first column,) at the Cape of Good Hope (second column,) we found the daily error, in the rate of its going, to be 2",26 (third column.) The longitude of that place, calculated on a supposition that the rate of the time-keeper had continued the same from the time of our leaving Greenwich, that is, had a regular daily error of 1",21, is found to be 18 deg. 26’ 30” east (fourth column.) And as its rate at Greenwich is, in this instance, its latest rate, the longitude thus found is the same (fifth column.) The true longitude of the place is 18 deg. 23’ 15” (sixth column.) From whence it appears, that in our run from Greenwich to the Cape, the watch would have led us into an error only of 3’ 15” (seventh column,) or three miles one quarter; or had varied 13” of time (eighth column,) in four months twenty-three days (ninth column,) the period between our leaving Greenwich and our arrival at the Cape.  As the Greenwich is the latest error, the tenth, eleventh, and twelfth columns, will be the same with the seventh and ninth.

But, on the 23d of February, 1777, (first column,) at Queen Charlotte’s Sound, New Zealand, (second column,) the daily error of its rate was found to be 2",91, (third column.) The longitude of this place, according to the Greenwich rate, is 175 deg. 25’, (fourth column.) But having found at the Cape, that it had altered its rate from a daily error of 1",21, to 2",26, the longitude corrected by this new rate is found to be 174 deg. 44’ 23”, (fifth column.) The true longitude of the place being 174 deg. 23’ 31”, (sixth column;) it appears that, in our run from Greenwich to New Zealand, the error would have been only 1 deg. 1’ 29”, (seventh column,) or sixty-one miles and a half, even if we had not had an opportunity of correcting its daily error; or, in other words, that the watch had varied 4’ 5",3, (eighth column,) in nine months four days, (ninth column.) But the longitude, as given by its new rate, leaves an error of only 30’ 54”, (tenth column,) near thirty-one miles, or, in time, 2’ 3",6, (eleventh column,) which has been accumulating during our run from the Cape to New Zealand, or in four months nine days, (twelfth column.) The thirteenth and fourteenth columns require no explanation.
