The night before we came out of Port Sandwich, two reddish fish, about the size of large bream, and not unlike them, were caught with hook and line. On these fish most of the officers, and some of the petty officers, dined the next day. The night following, every one who had eaten of them was seized with violent pains in the head and bones, attended with a scorching heat all over the skin, and numbness in the joints. There remained no doubt that this was occasioned by the fish being of a poisonous nature, and having communicated its bad effects to all who partook of them, even to the hogs and dogs. One of the former died about sixteen hours after; it was not long before one of the latter shared the same fate; and it was a week or ten days before all the gentlemen recovered. These must have been the same sort of fish mentioned by Quiros,* under the name of pargos, which poisoned the crews of his ships, so that it was some time before they recovered; and we should, doubtless, have been in the same situation, had more of them been eaten. [* Dalrymple's Collection of Voyages, vol. I. p. 140, 141.] At day break on the 25th, we made a short stretch to the east of Shepherd's Isles till after sun-rise, when seeing no more land in that direction, we tacked and stood for the island we had seen in the south, having a gentle breeze at S.E. We passed to the east of Threehills, and likewise of a low isle, which lies on the S.E. side of it, between a remarkable peaked rock which obtained the name of Monument, and a small island named Twohills, on account of two peaked hills upon it, disjoined by a low and narrow isthmus. The channel between this island and the Monument is near a mile broad, and twenty-four fathoms deep. Except this rock, which is only accessible to birds, we did not find an island on which people were not seen. At noon, we observed, in latitude 17 deg. 18' 30"; longitude, made from Port Sandwich, 45' E. In this situation, the Monument bore N. 16 deg. E. distant two miles; Twohills bore N. 25 deg. W. distant two miles, and in a line with the S.W. part of Threehills; and the islands to the south extended from S. 16 deg. 30' E. to S. 42 deg. W.
