ly all the time, till the island was out of fight; in this place they spoke a large fhip, the Captain of which, had no idea of his fituation; he had not noticed the bottom,. and was failing in full confidence of being far from danger. On being defired to look over the fide of his fhip, the whole crew was in the utmoft confternation, and hove the fhip too, with all her fails fett. He was foon informed of his true longitude, and took a new departure. Had this Captain kept a thermometrical journal he would not, probably, have been fo deceived, and had he at this time been in a gale of wind, his error might have been fatal. Every body in this city remembers the dreadful cataftrophe of the fhip Faithful Steward, which was loft, on this coaft, with near 500 people on board, about feven years fince. The Captain was fo fure of having fufficient fea room, that he did not think of founding, the weather was not boisterous and had he known his fituation he might have ftood off during the night. But fearless of a danger he did not know, he ftood on with full fails, and was in an inftant loft: I think there were not above twenty fouls faved. A thermometer regularly ufed would have given warning in time, and probably have faved these lives..

The impreffion fuch events have made on my mind, has induced me to be thus particular, and I the more readily do juftice, to the judicious example given to other Captains, by Captain Billings, becaufe I think the obfervations of a mariner, are more likely to be attended to by mariners, than any inftruction given by a landfman. I think befides, that the merit of Captain Billings, ought to be rewarded, by a publication of his laudable conduct,

that

that he may enjoy the reputation to which he is justly en.titled.

I am with great respect, Sir

Your moft obedient and

Moft humble Servant,

-Off Cape Henlopen.-N. B. The thermometer is on Fahrenheit's fcale and the longitude Weft from London. The days are reckoned to begin at Noon and to end at the fucceeding noon according to the ufage of navigators.

June 8th. at 10 A. M. being the firit alteration in the heat of the water after leaving the coaft it is fuppofed we entered the gulph

tream. The courfe is not across, but rather along this current, fomewhat diagonally however.

June 10th at noon it is fuppofed we are in the middle of the gulph ftream.

June 14th noon this fudden fall of 9° is fuppofed to be owing to the influence of the banks of Newfoundland which bear about N.

July 4th the water appears to have changed colour.

Land in fight, but frequently ob fcured by fog.

Land distant about 6 leagues.

Land distant about 2 leagues being the high land of Braganea nová

LTHOUGH the procefs of nature in the formation and reproduction of all organifed bodies is evidently uniform, yet there are philofophers and naturalifts who fcruple to admit this general principle in all inftances, and think it still liable to fome exceptions..
