ward from it for eight miles : its western side is formed by 
the Coronation Islands: its width is three miles, with good 
anchorage all over it. At the bottom is Careening Bay, 
where the Mermaid was repaired. The latitude of the 
beach in 15° 6' 18", and longitude 125° 0' 46"*. Port 
Nelson communicates with the sea to the westward of the 
Coronation Islands, which may be considered a strait. At 
the south-west end of the southernmost island, where the 
strait is narrowest, and not more than one mile and a quarter 
* The latitude of the observatory was taken every day during 
our stay, using the sea-horizon, but the effect of refraction was 
so great that the daily observations varied as much as S' 43". 
The mean of 15 meridional altitudes with 
the sextant made the latitude . , . 15° 6' 22".5 
and of fourteen observations with the circle 15 6 13 .8 
Mean for the latitude of the observatory 15 6 18 South. 
The longitude was deduced by the mean of the observations of 
our two visits ; viz.^ in October, 1820, and August, 1821 ; the 
latter were taken at Sight Point, in Prince Regent’s River, the 
difference of the meridians of the two places, by chronometers and 
survey, being S' 52". 8 
1820. Sept. 28 and 29. By twenty sets of lunar dis- 
tances with the sun, containing one hundred 
sights with the sextant, the sun being to the east 
of the moon, the longitude is . . . . 125° 11' 24".3 
1821. August 2nd and 3rd. By seventeen sets of 
lunar distances with the sun, containing eighty- 
five sights with the sextant, the sun being to the 
west of the moon, the longitude of Sight Point, 
in Prince Regent’s River, was found to be 
124° 41' 15".3, or of Careening Bay , . 124 50 8.1 
The mean is the longitude of the observatory 125° O' 46"E.
