e 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 3 minutes 43 seconds.

The mean of 15 meridional altitudes with the sextant made the latitude 15
degrees 6 minutes 22.5 seconds,
and of fourteen observations with the circle 15 degrees 6 minutes 13.8
seconds.
Mean for the latitude of the observatory 15 degrees 6 minutes 18 seconds
South.

The longitude was deduced by the mean of the observations of our two
visits; namely, 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 8 minutes 52.8
seconds.

1820. September 28 and 29. By twenty sets of lunar distances with the
sun, containing one hundred sights with the sextant, the sun being to the
east of the moon, the longitude is 125 degrees 11 minutes 24.3 seconds.

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 degrees 41 minutes 15.3 seconds, or of Careening Bay
124 degrees 50 minutes 8.1 seconds.

The mean is the longitude of the observatory 125 degrees 0 minutes 46
seconds East.)

The CORONATION ISLANDS separate York Sound from Brunswick Bay, and are
situated in front of Port Nelson. The group consists of seventeen or
eighteen islands, besides numerous rocky islets. On the largest island
are two remarkable peaks; the easternmost is in 14 degrees 59 minutes,
and longitude 124 degrees 56 minutes 5 seconds. The island is eight miles
long, and from four to two wide; the others are from three to one mile in
length; they are covered with vegetation, and the larger islands are well
clothed with trees. The great rise of the tide would render this part of
the coast of importance, was it not for the wretched state of the
country, and the unproductiveness of its soil, which are great drawbacks
upon the advantage of the tide's unusual rise. It is high water at full
and change in Port Nelson at twelve o'clock, as it is also in Montagu
Sound.

Beyond the Coronation Islands there is a string of small, rocky islands
extending for sixteen miles: the westernmost is Freycinet's Group; the
principal island of which Captain De Freycinet has describ
