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.
