Abstract
THE study of the probable mode of formation of coal and kindred substances has for many years engaged the attention of Prof. Potonié, who, as palseobotanist in the University of Berlin, and also as a member of the Geological Survey of Prussia, has had exceptional opportunity for such study, both in the cabinet and in the field. At the York meeting of the British Association in 1906, he laid before the Botanical Section his views on the origin of coal, and the following year issued the fourth edition of his little work, “Die Entstehung der Steinkohle, u.s.w.”—an octavo of only forty-seven pages, which was briefly noticed in NATURE (vol. lxxviii., p. 86). In the new edition, recently published, the work has been considerably enlarged, and the title so modified as to indicate that it deals with the origin of caustobioliths generally.
