THE PACIFIC OCEAN. 121 



Agreeably to the practice of Captain Cook, I fhall fubjoin *779- 

 an abftraet of the aftronomical obfervations which were 

 made at the obfervatory in Karakakooa Bay, for determin- 

 ing its latitude and longitude, and for finding the rate and 

 error of the time-keeper. To thefe are fubjoined the mean 

 variation of the compafs, the dip of the magnetic needle, and 

 a table of the latitude and longitude of the Sandwich Iflands. 



The latitude of the obfervatory, deduced 

 from meridian zenith diftances of the 

 fun, eleven ftars to the South, and 

 four ftars to the North of the zenith 19 28' o" North. 



The longitude of the obfervatory, de- 

 duced from 253 fets of lunar obferva- 

 tions; each fet confiding of fix ob- 

 ferved diftances of the fun from the 

 moon, or ftars ; 14 of the above fets 

 were only taken at the obfervatory, 

 105 fets being taken whilft cruizing 

 off Owhyhce ; and 154 fets, when at 

 Atooi and Oneehcow ; all thefe being 

 reduced to the obfervatory, by means 

 of the time-keeper - - 204° o' o" EarL 



The longitude of the obfervatory, by 

 the time-keeper, on the 19th January 

 1779, according to its rate, as found at 

 Greenwich - - - 214" y r 1 5" Eaft. 



The longitude of the obfervatory, by 

 the time-keeper, on the 19th January 

 1779, according to its rate, corrected at 

 different places, and laft at Samga- 

 noodha Harbour, in Oonalafchka - 203* 3.7' 22" Eaft.
