Note 289 — Chapter XL · THE MODERN VOLCANOES OF ICELAND AS ILLUSTRATIVE OF THE TERTIARY VOLCANIC HISTORY OF NORTH-WESTERN EUROPE

In his memoir of 1874, Professor Judd announced his conclusion that there were formerly five great volcanoes amongst the Western Isles, and that the lavas of the plateaux had issued from these. He subsequently reiterated this view (Quart. Journ. Geol. Soc. xlv., 1890, p. 187), and ridiculed the explanation of fissure-eruptions. The evidence adduced by me in a paper published in 1896 (same journal, vol. lii. p. 331) and reprinted with additions in this chapter, will, I trust, be regarded by geologists as having finally settled this question.
