A yOYAGE TO 



Book I. 



Journal of Don GEORGE JUAN, on board the 

 Conquistador. 



THE fecond of June, 1735, faw the Canary 

 iflands ; and the winds, which are ufually very 

 variable in this pafTage, were either N. W. by N. or 

 Tsf. E. Don George Juan, by his reckoning, found 

 the difference of longitude between Cadiz and the 

 Pico of TenerifFe 10° 30'. 



According to father Feuillee's obfervations, made 

 at Lorotava, fix minutes and a half eaft of the Pico, 

 the difference of the longitude betwixt the latter and the 

 obfervatory at Paris is 18° 51'* Subtradting therefore 

 8° 27', which, according to the ConnoiiTance des terns, 

 is the difference of longitude between that obferva- 

 tory and Cadiz ; the difference of longitude between 

 that city and the Pico is lo"" 24, and confequently 

 difiers 6 minutes from Don George's reckoning. 



On the 7th we loft fight of the Canaries, and con- 

 tinued our courfe towards Martinico, fteering fouth 

 between 42 and 45 degrees wefterly, increafing the 

 angle every day, till, near the ifland, we fteered due 

 weft under its parallel, and on the 26th of June dif- 

 covered Martinico and Dominica, 



The difference of longitude between Cadiz andMar- 

 tinico appeared, from our reckoning, to be 59° 55', that 

 isj 3° 55' more than the chart of Antonio de Matos 

 makes it which is however generally followed in this 

 voyage. According tq the obfervations of father La- 

 val, made at Martinico, the difference of longitude 

 is 55° 8' 45"; according to thofe of father Fevillee, 

 55° 19'. This error in a great meafure proceeds from 

 a want of accuracy in the log-line; for had the pilot 

 of the Conquiftador, who found the fame defetl in 

 his calculations, made the diftance between the knots 

 of the log-line 30 Englifh feet, inftead of 47 and a
