On the 16th, at noon, St Agnes's light-house on the isles of Scilly bore N.W. by W., distant seven or eight miles. Our latitude was now 49° 53' 30" N., and our longitude, by the watch, 6° 11' W. Hence, I reckon that St Agnes's light-house is in 49° 57' 30" N. latitude, and in 6° 20' of W. longitude. On the 17th[68] and 18th we were off Ushant, and found the longitude of the island to be, by the watch, 5° 18' 37" W. The variation was 23° 0' 50", in the same direction. [Footnote 68: It appears from Captain Cook's log-book, that he began his judicious operations for preserving the health of his crew, very early in the voyage. On the 17th, the ship was smoked between decks with gunpowder. The spare sails also were then well aired.--D.] With a strong gale at S., on the 19th, we stood to the westward, till eight o'clock in the morning; when the wind shifting to the W. and N.W., we tacked and stretched to the southward. At this time, we saw nine sail of large ships, which we judged to be French men-of-war. They took no particular notice of us, nor we of them. At ten o'clock in the morning of the 22d, we saw Cape Ortegal; which at noon bore S.E. 1/2 S., about four leagues distant. At this time we were in the latitude of 44° 6' N.; and our longitude, by the watch, was 8° 23" W. After two days of calm weather, we passed Cape Finisterre on the afternoon of the 24th, with a fine gale at N.N.E. The longitude of this cape, by the watch, is 9° 29' W.; and, by the mean of forty-one lunar observations, made before and after we passed it, and reduced to it by the watch, the result was 9° 19' 12". On the 30th, at six minutes and thirty-eight seconds past ten o'clock at night, apparent time, I observed, with a night telescope, the moon totally eclipsed. By the _ephemeris_, the same happened at Greenwich at nine minutes past eleven o'clock; the difference being one hour, two minutes, and twenty-two seconds, or 15° 35' 30" of longitude. The watch, for the same time, gave 15° 26' 45' longitude W.; and the latitude was 31° 10' N. No other observation could be made on this eclipse, as the moon was hid behind the clouds the greater part of the time; and, in particular, when the beginning and end of total darkness, and the end of the eclipse, happened. Finding that we had not hay and corn sufficient for the subsistence of the stock of animals on board, till our arrival at the Cape of Good Hope, I determined to touch at Teneriffe, to get a supply of these, and of the usual refreshments for ourselves; thinking that island, for such purposes, better adapted than Madeira. At four in the afternoon of the 31st, we saw Teneriffe, and steered for the eastern part. At nine, being near it, we hauled up, and stood off and on during the night.
