This second part of volume XIV completes the presentation of the subject of reproduction, development and growth. The first part of this volume was reviewed in these pages some time ago. The present part contains the index for the entire volume. Parenthetically, it may be remarked that any subscriber to a part obligates himself to buy the entire volume. The first sixteen pages (by Professor Küster) are devoted to a presentation of "new formations" in plants. The remainder of the book (by Professor Fischer-Wasels of Frankfort-on-the-Main) deals with the various aspects of metaplasia, tissue and tumor formation. Although this book is of particular value to the pathologist, the physiologist will find the authoritative summary of the status of tumor research highly welcome. American contributions are credited fully, particularly the extensive and careful studies of Maud Slye.
