OBSERVATIONS 



ON THE 



FLOATING ICE, 



WHICH IS FOUND 



IN HIGH NORTHERN, AND SOUTHERN LATITUDES. 



SINCE the return of the King's mips from voyages of dis- 

 covery, both in high Northern and Southern latitudes, I 

 have found that it hath been a difputed point, whether the ice 

 which they have met with was formed chiefly from the fait 

 or frefh water. I mould rather conceive that this doubt mull: 

 have arifen from what is mentioned by the great Mr. Boyle, 

 in his experiments on heat and cold ; or from an obfervation of 

 M. Adanfon, at the end of his voyage from Senegal, becaufe 

 from the quantity of ice merely (at leaft to the Northward) the 

 early navigators never conceived that it was produced from 

 fea water. 



In full proof of this, not to ftate the opinion of feveral others 

 on the fame head, I mail content myfelf with citing that of 

 Sir Martin Frobiftier, who is well known to have made three 

 fucceffive voyages to Greenland, with a further intent of dif- 

 covering the North Weft paflage from Europe to the Pacific 



Ocean.
