YR 1857 UL http://jgs.lyellcollection.org/content/13/1-2/240.2.abstract AB In a previous memoir (Quarterly Geological Journal, vol. xii. p. 144), I have described the conditions of the great copper lode of Cobre in the island of Cuba. I have now to offer remarks on three lodes, or rather groups of lodes; one in the central part of the same island (Cuba), and the others situated in the United States of North America.
