Geological magazine : Vol. 78 Iss. 1-6 Year. 1941Summary: A Recent paper in this journal by K. P. Oakley (1940) has drawn attention to certain structures in Recent rhyolitic ashes of Malaya, and contraverts the earlier view that these structures represent sponge spicules. Oakley suggests tentatively that most of them are the casts of minute spherical and tubular hollows in the material of the ashes. It may be of interest, therefore, to describe comparable material from New Zealand which appears to support this suggestion.
