470 cook's VOYAGE TO JULY, 



The longitude, by the mean 

 of one hundred and thirty- 

 one sets of lunar observ- 

 ations, amounting to above 

 a thousand observed dis- 

 tances, between the moon, 

 sun, and stars, - 184 55' 18" east* 



The difference of longitude, 

 made by the time-keeper, 

 between the above obser- 

 vatory, and that at Anna- 

 mooka, - - - 16 



Hence, the longitude of

By the time-keeper it is,

Its latitude 



N. B. The observatory at Tongataboo was neai? 

 the middle of the north side of the island ; and that 

 at Annamooka, on its west side ; but the chart will 

 elucidate this. 



The time-keeper was too slow for mean time at 

 Greenwich, on the first of July at noon, by 12 h 34 m 

 33%%-, and her daily rate, at that time, was loosing, 

 on mean time, l m ,783 per day. This rate will 

 now be used for finding the longitude by the time- 

 keeper ; and 184 55' 18", or 12 h 19 41%2, will be 

 taken as the true longitude of Tongataboo, east from 

 Greenwich. 



By the mean of several observations, the south 

 end of the needle was found to dip
