Abstract

The occurrence in Tasmania of these singular spheroids
of jet black obsidian, popularly known as "buttons," was
brought under the notice of the Royal Society in 1897,
by Messrs. Twelvetrees and Petterd, who gave a very
full description of the specimens which had come under
their observation, and discussed the various theories
which have been put forward to account for their origin
and distribution.
