From Callao to Guayaquil the longitudes depend upon Mr. Usboriie's survey, in the Consti- 

 tucion. He had three chronometers fixed on board the vessel, and one which was used for . 

 observations ; all four were good watches. If his whole meridian distance between Guayaquil 1 1 

 and Callao is incorrect, the error, whatever it may be, must be distributed equally along that { 

 j)ortion of coast, but I do not think there is an error of two miles ; probably, indeed, there is not ' 

 near so great a deviation from truth, as Mr. Usborne landed for observations continually, and 

 can"ied a connected triangulation from Callao to Pun^.
