The track of the Fair-American appears to have laid 

 very near to Jaquet ifland, which in governor Pownall's

 was kept for feveral days, but with no efFedx ; this may

The journal from America to England, does little more 

 than confirm the previous obfervations made in this track ; 

 the thermometer fell no lefs than 20 degrees on pafling 

 to the ibuth-eaft of Newfoundland, and rofe again 9 de- 

 grees in the fame longitudes where in our outward bound 

 voyage, we fuppofed ourfelves to be crcffing a branch 

 of the gulf-ftream. The fall from hence of the ther- 

 mometer, as the coaft of Europe h approached is very 

 remarkable and uniform.
