e A VOYAGE TO Book I. 



'Journal of Don George yuaft, on board the 

 Conquijiador, 



THE fecond of June 1735, favv the Canary 

 iilands ; and the winds, which are uiually very 

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

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

 the difference of longitude between Cadiz and the 

 Pico of TenerifFe 10° 30'. 



According to father Fenillée's obfervations, made 

 at Loratava, iix minutes and a half eail of the Pico, 

 the difference of the longitude betwixt the latter and 

 the obfervatoay at Paris is 1 8° 5 1'. Snbtrafting there- 

 fore 8° 27', which, according to the Connoiffance des 

 Terns, is the difference of longitude between that ob- 

 fervatory and Cadiz ; the difference of longitude be- 

 tween that city and the Pico is 10° 24', and conie- 

 quently differs 6' from Don George's reckoning. 



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

 tinued our courfe towards Martinico, fleering fouth 

 between 42 and 45 degrees wefierly, increañng the 

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

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

 covered Martinico and Dominica. 



The difference of longitude between Cadiz and Mar- 

 tinico appeared, from our reckoning, tobe 59° 53', that 

 is, 3° 35' more than the chart of Antonio de Matos 

 makes it; which is however generally followed in this 

 voyage. According to the obfervations of father La- 

 val, made at Martinico, the difference of longitude 

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

 53° 19'. This error in a great meafure proceeds froni 

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

 of the Conquiftador, who found the fame defeat in 

 his calculations, made the diftance between the knots 

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



half,
