PREFACE.
(BY THE EDITOR.)
The present volume contains the first portion of the works of the distinguished author, now for the first time collected in England, and reprinted from the originals, without change, in accordance with his express desire. It had been his intention to reprint them himself with annotations, but, unfortunately for science, this intention was never carried out, and it remained for the Editor simply to superintend a verbatim reprint.
The Memoirs are arranged in three divisions—1st. Geographico-Botanical; 2nd. Structural and Physiological; 3rd. Systematic. Of course this arrangement is in some degree arbitrary, inasmuch as observations relating to both of the other divisions are continually occurring in the Memoirs referred to each of them; but, on the whole, it has appeared to be the most convenient for reference. The present volume contains the first two of these divisions; the second will be devoted to Systematic Memoirs and Miscellaneous Descriptions of Plants; and a separate volume, in large 4to, will contain the illustrative figures to both.
