Excerpt from Geological Magazine, 1875, Vol. 2 The first attempt at a general treatise on Vulcanology was that (f Mr. Scrope in 1825. Unfortunately, while following out the two lines of inquiry which we have just indicated, and attaining many important results, the correctness and value of which have been established by subsequent investigations, the author permitted him self to be drawn aside from the true paths of geological inquiry into the speculations of Cosmogony. No one was more conscious of this blemish of his work than the author himself, as was shown by the subsequent publication of his well-known work, The Geology and Extinct Volcanos of Central France, in which this error is most carefully avoided; and also in a second edition of his general treatise.
