I have endeavoured to run on the limits of Tristan da Cunha with the hopes of making it, but thus far I am disapointed. My only authorities for its situation are Robertsons Elements that place it in 37°..12′ So. 13..23 Wt. and the general map prefixed to Captn. Cooks last Voyage which place it in 37°..12′ So. & Longd. 15°..00′ West. This last being the Westermost I entered on that Tract in Time but I met with no signs of land or the least appearance of any Vicinity of it: however I thought it would not be loosing much time to try its Eastermost Situation. I therefore at 8 oClock stood on and off untill daylight; that I might not pass it in the night. I then stood for it in its parralell, by my account which at Noon proves to be 17 Miles wrong but I could see land of any moderate height at least 8 or 10 leagues, besides this there was no signs of nearness of land only a very few oceanic Birds being about. At Noon I steered NE both to intersect its latitude and be beyond its Eastermost situation carrying a Scope of Ten & Twelve leagues in view, but how far the limits this Island & Rocks are determined I cannot now with propriety search any longer after. My Observations being sufficient Intervals and near noon I think may be relyed on equal to a meridian altitude.
By a presumed Rate as I call it, found from Lunar Observations I find the true Longd. by T. Keeper to day at Noon to be 13°..30 West which I consider to be within ¼ of a degree exact, & from this taking its situation from Robertson the Island bears N20Et dist 16 miles.
