Abstract

(1) DR FERNAND PELOURDE, préparateur at the National Museum of Natural History, is publishing, under the auspices of the Encyclopédic Scientifique, an account of palæobotany in accordance with present knowledge. In this, the first volume, he deals with cellular and vascular cryptogams; in two subsequent volumes he will deal with gymnosperms and angiosperms, and will also formulate general conclusions from botanical and geological points of view. M. R. Zeiller, to whom the volume is dedicated, has written the preface. The text comprises a short introduction on the methods of preservation of fossil plants and a classified list of geological strata. The great plant-groups are then studied in order beginning with bacteriaceæ, including reference to their work in formation of coal. The chapter on the cellular cryptogams occupies only twenty-two pages, but the reader is referred to numerous papers dealing especially with fossil algæ. The groups of vascular cryptogams are considered in the following order: equisetales, sphenophyllales, lycopodiales, filicales. The little volume, which presupposes some knowledge of general botany, especially anatomy, gives a somewhat condensed review of the subject, but will enable the student of botany to form an idea of the present position of our knowledge of the groups considered so far as concerns extinct forms. A useful feature is the bibliography which follows the subject matter.
