Whilst employed in collecting some sea-weed floating about the ship, I observed a species of Physalia, so small and transparent that I at first mistook it for an air-bubble; but on catching it in my hand was soon convinced of my error, for wrapping its long tendrils round one of my fingers it stung like a nettle, but with much more severe effect. In about five minutes the pain in my finger abated, but an uneasy sensation extended up the inside of my arm, which soon terminated in an aching pain in the arm-pit, accompanied by a sense of restriction in my chest : within fifteen minutes all uneasiness ceased.
