were about the ship, and the state of the sea admitted of going after
them--by this means many species of petrels were obtained for the
collection. On one of these occasions, owing to a mistake in lowering the
stern boat before the ship had quite lost her way through the water, one
of the falls could not be unhooked in time; consequently the boat was
dragged over on her broadside, and finally capsized with eight people in
her. Some reached one of the life-buoys, which was instantly let go, the
others managed to roll the boat over and right her, full of water. All
were eventually picked up by the leeward quarter-boat; the weather one,
from the shortness of the davits, would not clear the ship's side, but
turned over on her bilge, dipping in the water, and was rendered
ineffective when most wanted. This defect in the davits was afterwards
remedied by the substitution of other and longer ones, which had formerly
belonged to H.M. steam vessel Thunderbolt, wrecked at Algoa Bay a short
time previously.

OCEANIC BIRDS.

Among many interesting birds* procured in the above-mentioned manner, I
may allude to Puffinus cinereus, a European species of shearwater, which
was found to be generally distributed across the South Atlantic between
the meridians of 28 degrees West and 1 1/2 degrees East; on two
successive days, while in the neighbourhood of Tristan da Cunha, myriads
of these birds passed the ship to the westward, apparently coming from
that island. A few days afterwards, while 480 miles from the nearest
land, we caught a beautiful tern (Sterna melanorhyncha) hitherto
considered to be peculiar to Australia.

voyage, with a view to determine the geographical distribution of the
