APPENDIX, No. II. 



TABLE OF THE LATITUDES, LONGITUDES, AND VARIATION OF THE COMPASS 

 OF THE VARIOUS PORTS ON THE SHORES OF THE PACIFIC OCEAN, 



VISITED BY HIS MAJESTY'S SHIP CONWAY, IN 1820, 1821, AND 1822. 

 From a Hydrographical Memoir, by Mr. Henry Foster, R.N., in 1823, corrected in 1840. 



N.B. — All the longitudes, up to those of the Galapagos inclusive, have been augmented by 9' 18", that being the 

 presumed error in the longitude of Valparaiso, by the observations made on board the Conway, from whence all the 

 others were deduced. That longitude, as determined by Mr. Foster and myself, was 71° 31' 0"; but I have now 

 altered it to 71° 40' 18", which is the mean of all the most recent astronomical determinations. See Lieutenant 

 Raper's article on Longitudes, in the Nautical Magazine for 1839, page 755. I have left the differences of longitude, 

 however, as we measured them by our chronometers between Valparaiso and the different parts of the coast. — B. H.
