6 x September 1748. 



pretty common, and the confequence of a pre- 

 ceding heat in the atmofphere ; but that when 

 lightening^ were obferved in winter, prudent 

 navigators were ufed to reef their fails, as they 

 are by this fign certain of an impendent florm ; 

 and fo likewife in that feafon, a cloud rifing 

 from the north-weft, is an infallible forerunner 

 of a great tempeft. 



Sept. yth. As we had the firft day of the 

 month contrary wind, on the fecond it fhifted 

 to the north, was again contrary the third, and 

 fair the fourth and following days. The fifth 

 we were in forty deg. three min. north lat. and 

 between fifty- three and fifty- four deg. weft long, 

 from London. 



BESIDES the common waves rolling with the 

 wind, we met on the 4th and 5th inft. with 

 waves coming from fouth-weft, which the cap- 

 tain gave as a mark of a former ftorm from that 

 quarter in this neighbourhood. 



Sept, 8th. WE croffed by a moderate wind, 

 a fea with the higheft waves we met on the 

 \vhole paffage, attributed by the captain to the 

 divifion between the great ocean and the inner 

 American gulf; and foon after we met with waves 

 greatly inferior to thole we obferved before. 



Sept. gth. IN the afternoon we remarked that 

 in forne places the colour of the fea (which had 

 been hitherto of a deep blue) was changed into 

 a paler hue ; fome of thefe fpots were narrow 

 ftripes of twelve or fourteen fathoms breadth, of 

 a pale green colour, which is fuppoftd to be 

 caufed by the fand, or, as fome fay, by the weeds 

 under water.
