Cook gives, in this place of his Journal, a table 

 of the tides in thofe iflands, from the firft up to the 

 twenty- fixth of November; from which it is evi- 

 dent that they had but one tide a day, and this, dur- 

 ing the whole courfe of the month, was at it's 

 mean height, between eleven and one o'clock. It 

 is, accordingly, evident, that tides fo regular, at 

 epochs of the Moon fo different, could have no 

 relation whatever to the phafes of that luminary. 



Cook was at Taïti, in 1 769, in the month of July, 

 that is, in the winter of the South Pole : He was 

 there a fécond time, in 1777, in the month of De- 

 cember, that is, in it's fummer ; it is accordingly 

 poffible, that the effufions of this Pole, being then 

 more copious, and nearer to Taïri, than thofe of 

 the North-Pole, the tides mJght be ftronger in that 

 ifland, in the month of December, than in July, 

 and that Mr. IVûks, the Aftronomer, was in the 

 right. 



Let us now obferve the effeds of the tides, in the 

 northern part of the South Sea.
