116 cook's second voyage may, 



natural to man, but observed even by the brute cre- 

 ation. 



I shall conclude this account of Dusky Bay with 

 some observations made and communicated to me by 

 Mr. Wales. He found, by a great variety of ob- 

 servations, that the latitude of his observatory at 

 Pickersgill Harbour, was 45 47' 26i" south ; and 

 by the mean of several distances of the moon from 

 the sun, that its longitude was 166 18' east ; which 

 is about half a degree less than it is laid down in my 

 chart constructed in my former voyage. He found 

 the variation of the needle or compass by the mean of 

 three different needles, to be 13 49' east, and the 

 dip of the south end 70 5f . The times of high 

 water on the full and change days, he found to be at 

 10 h 57', and the tide to rise and fall at the former 

 eight feet, at the latter five feet eight inches. This 

 difference in the rise of the tides between the new 

 and full moon is a little extraordinary, and was pro- 

 bably occasioned, at this time, by some accidental 

 cause, such as winds, &c. but be it as it will, I am 

 well assured there was no error in the observations. 



Supposing the longitude of the observatory to be as 

 above, the error of Mr. Kendal's watch, in longitude, 

 will be 1 48', minus, and that of Mr. Arnold's 

 39 25". The former was found to be gaining 

 6", 461 a-day, on mean time, and the latter losing 

 99", 361. Agreeably to these rates, the longitude by 

 them was not to be determined until an opportunity 

 of trying them again. 



1 must observe, that in finding the longitude by 

 Mr. Kendal's watch, we supposed it to have gone 

 mean time from the Cape of Good Hope. Had its 

 Cape rate been allowed, the error would not have 

 been so great.
