In a letter dated the 6th day of January, 1791, which I did myself the honour to address to you from Rio Janeiro I gave an account of my proceedings up to that time and inclosed the state and condition of His Majesty's Ship _Pandora_ under my command, and having compleated the water and procured such articles of provision, etc., for the use of the Ship's Company as they were in want of and I thought necessary for the voyage, I sailed from that port on the 8th January, 1791, run along the coast of America, Tierra Del Fuego, Hatin Land, round Cape Horn and proceeded directly to Otaheite, and arrived at Matavy Bay in that Island on the 23rd March without having touched in any other place in my passage thither. It was my intention to have put into New Year's harbour, or some other port in its neighbourhood to complete our water and to refresh my people, could I have effected that business within the month of January; but as I arrived too late on that coast to fulfil my intentions within the time, it determined me to push forward without delay, by which means I flattered myself I might avoid that extreme bad weather and all the evil consequences that are usually experienced in doubling Cape Horn in a more advanced season of the year, and I had the good fortune not to be disappointed in my expectation. After doubling the Cape, and advancing Northward into warmer weather, the fever which had prevailed on board gradually declined, and the diseases usually succeeding such fevers prevented by a liberal use of the antiscorbutics and other nourishing and useful articles with which we were so amply supplied, and the ship's company arrived at Otaheite in perfect health, except a few whose debilitated constitutions no climate, provisions or medicine could much improve.
