The tide rises and falls very little, and, being governed by the winds, is very uncertain; though they generally blow from the E. to the S.E., and for the most part a pleasant breeze.
The benefit that we received while we lay off this island, with respect to the health of the ship's company, was beyond our most sanguine expectations, for we had not now an invalid on board, except the two lieutenants and myself, and we were recovering, though still in a very feeble condition.
It is certain that none of our people contracted the venereal disease here, and therefore, as they had free commerce with great numbers of the women, there is the greatest probability that it was not then known in the country. It was, however, found here by Captain Cook, in the Endeavour, and as no European vessel is known to have visited this island before Captain Cook's arrival, but the Dolphin, and the Boudeuse and Etoil, commanded by M. Bougainville, the reproach of having contaminated, with that dreadful pest, a race of happy people, to whom its miseries had till then been unknown, most be due either to him or to me, to England or to France; and I think myself happy to be able to exculpate myself and my country beyond the possibility of doubt.
It is well known that the surgeon on board his majesty's ships keeps a list of the persons who are sick on board, specifying their diseases, and the times when they came under his care, and when they were discharged. It happened that I was once at the pay-table on board a ship, when several sailors objected to the payment of the surgeon, alleging, that although he had discharged them from the list, and reported them to be cured, yet their cure was incomplete. From this time, it has been my constant practice when the surgeon reported a man to be cured, who had been upon the sick-list, to call the man before me, and ask him whether the report was true: If he alleged that any symptoms of his complaint remained, I continued him upon the list; if not, I required him, as a confirmation of the surgeon's report, to sign the book, which was always done in my presence. A copy of the sick-list on board the Dolphin, during this voyage, signed by every man in my presence, when he was discharged well, in confirmation of the surgeon's report, written in my own hand, and confirmed by my affidavit, I have deposited in the Admiralty; by which it appears, that the last man on board the ship, in her voyage outward, who was upon the sick-list for the venereal disease, except one who was sent to England in the store-ship, was discharged cured, and signed the book on the 27th of December, 1766, near six months before our arrival at Otaheite, which was on the 19th of June, 1767; and that the first man who was upon the list for that disease, in our return home, was entered on the 26th of February, 1768, six months after we left the island, which was on the 26th of July, 1767; so that the ship's company was entirely free fourteen months within one day, the very middle of which time we spent at Otaheite; and the man who was first entered as a venereal patient, on our return home, was known to have contracted the disease at the Cape of Good Hope, where we then lay.
