3IO A VOYAGE TO Book: IX. 



On' the 15th of Mav, n.imfly, before he began to 

 fteer W. we fpoke with the Marquis d'Antin, and he 

 captain gave us to undeiftand, that according to his 

 reckoning, the fhip was then 45°, 3', E. of the meri- 

 dian of Conception. Whereas tht diftance, according 

 to my account was only 34°, 19'. Thus the.ihip, ac- 

 cording to his computation, was iG°, 44*, further to 

 the eail>vard thin by tninr, and the diíTcrence on the 

 ihip's arrival at the illand, will be 2°, the diitance the 

 currents had carried him to the eaftward beyond what 



' he had judged. The captain of the Deliverance, on 

 the fame day, made tne ihip 39°, 15', eail of the me- 

 ridian of Conception ; that is 4°, 56', more than I; 

 and confequericly on rea'ching the ifland, his account 

 was 7°, 40', further to the weftward than the fhip. 

 Others, who kept a journal on board the Delivrance, 

 differed as much ; fome nearly agreeing with me, 



• namely, thofe who had made no allowance for the 

 currents; whilil others approached nearer to the ac- 

 count of the captain of the Marquis d'Antin, having 

 ufed an equation in rcfped to the currcnrs. But every 

 one, at making the ifland, found their reckoning er- 

 roneous ; the ihip. according to their accounts, being 

 farther to the weftward than fhe. really wasj but dif- 

 fered in the quantity of that error, according to the 

 different allowances they had made for the letting of 

 the currents. 



The difference betwixt my account and that of 

 the captain of the Murquis d'Antin, who was one of 

 thofe who made thr ihip fai theft to the eaftward, pro- 

 ceeded from the captain's knowing by c.bferving the 

 variation of the needle, that the frigates made more 

 way than the reckoning allowed of, and therefore con- 

 cluded that a correólion was neceflary, whicn he per- 

 formed by adding a proper diftance, from the journals 

 of others, and thence inferred that the velocity of the 

 currents was confiderable ; but as that really exceeded 

 the allowance he made for it, his ihip was always to
