V.—Modern ‘Vulcanicity.’

open access: yesGeological Magazine, 1875
The theory proposed of late years by Mr. Mallet to account for volcanic and earthquake phenomena, while having a charm about it from its very simplicity, is one which must nevertheless meet with very decided criticism from geologists.
