curlews; and we saw in the upper part, some pelicans, an individual 
of a large kind of crane, and another of a white bird, in form re- 
sembling a curlew. Many turtle were seen in the water about Long 
Island, and from the bones scattered around the deserted fire places, 
tins animal seemed to form the principal subsistence of the natives ; 
but we had not the address to obtain any. Hump-backed whales 
frequent the entrance of the sound, and would present an object of 
interest to a colony. In fishing, we had little success with hook and 
line; and the nature of the shores did not admit of hauling the seine. 
The climate here, being one degree within the tropic, was 
warm at this season, which may be considered as the spring and the 
driest time of the year. On board the ship, the height of the ther- 
mometer did not exceed 76®, with the warm winds from the north- 
ward, but at the tents it averaged at noon somewhat above 9 o*; and 
the muskctoes and sand flies were very troublesome at all places 
near the mangroves. We did not see any snakes or other venemous 
reptiles or insects.

observations in the artificial horizon, is - 22° 23' 24" S

The errors of the time keepers from mean Greenwich time, at 
noon there Sept. 26, and their mean rates of going during seven days, 
of which four were before and three after they had been let down 
the second time, were as under : 
Earnshaw’s No. 543 slow 2 h 3' 37", 23 and losing 9, "62 per day. 
No. 520 -32 9 15, 57 . _ 21,41 
These errors and rates were found by lieutenant Flinders, from equal 
altitudes taken with a sextant on a stand, and using an artificial 
horizon of quicksilver. 
The longitudes given by the time keepers on Sept. 12 a. m. at 
Uppet Head, with the Port-Jackson rates, were these:
