Longitude Quotes
Sir,
Having long deferred to make any report relating to the observations that were taken at sea by captain Campbell, in the year 1757, which you transmitted to me by order of the lords of the admiralty, I think it necessary to acquaint you, that, upon examining those observations, I perceived that they were not in all respects accompanied with such circumstances as are requisite for forming a right judgment of the accuracy and certainty with which observations proper for finding the longitude at sea by the moon can in fact be taken; for which reason I delayed giving my opinion upon this point till I could have an opportunity of comparing a greater variety of observations, made at different times, and with different instruments: such an opportunity having lately been given me by captain Campbell, who has favoured me with a copy of several observations that were made by him in 1758 and 1759, I now beg leave to lay before their lordships the result of the comparisons which I have made.

By an observation of an eclipse of one of Jupiter's satellites, on the night of the 25th of March, in latitude 350° 51' 30", I found that we were very near the 100th degree of longitude west from Greenwich. On the following day, therefore, we celebrated our entrance into the United States territory. Those who have never been beyond the purlieus of the land of their nativity, can form but a poor conception of the joy which the wanderer in distant climes experiences on treading once more upon his own native soil! Although we were yet far from the abodes of civilization, and further still from home, nevertheless the heart within us thrilled with exhilarating sensations; for we were again in our own territory, breathed our own free atmosphere, and were fairly out of reach of the arbitrary power which we had left behind us.
