This would place us 1°.15' West of the Long. made by G.H's chron. last Fall, on Anchoring here, - that is only 34 1/4 nautical miles at this latitude. Future observations that I expect to make will truly determine this matter of our Long. The Lunars that I am yet to take will approximate to the true Longitude. I must determine [[underlined]]one Meridian[[/underlined]] then from it I can determine all others hereabouts.
