Abstract

REFERRING to the very kind review by Prof. H. Louis of my book “The Geology of the Metalliferous Deposits” in NATURE of June 7, p. 812, I wish to direct attention to one point. Prof. Louis quotes the following sentence: “It would perhaps be too much to say in the present state of our knowledge that all primary ore-deposits are of igneous origin, but this is a view which may very likely be established as a result of future work.” He then goes on to instance the hæmatite deposits of Cumberland as ores which are certainly not of igneous origin. With this, of course, I entirely agree, and I wish to say that my statement was certainly never meant to include them, as may be seen by referring to p. 330 of my book. The emphasis in the sentence quoted is on the word primary, whereas I regard the hæmatites of Cumberland and northern Spain as secondary ores. Should a second edition of the book be called for, steps will be taken to make this point quite clear.
