all its synonyms, is omitted with much of the complex nomenclature and special doctrines of this new and aspiring science, while the American authors present a grand chapter on the Origin and Descent of Rocks,' starting with a molten magma (but discrediting a molten globe), and presenting the new quantitative classification of Iddings and Washing

ton.

Fossils are next treated with great brevity in an excellent chapter of twelve pages. Much is omitted here that appears in Pennell, Cole and Keilhack and might have been expected in a manual of field geology. The book is rather' planned for an advanced course in geology in Scotland with some field work, and it is interesting to note the classes for which it is intended according to the enumeration in the preface, viz., mining engineers, civil engineers, architects, agriculturists and public health officers.

There follow chapters written with great fullness and clearness upon the main geological structures, stratification, concretions, folding, joints and faults, the structure of eruptive rocks, and ore formations. The book is here at its best. The illustrations are abundant, well chosen and clear and the plan of printing many of the important figures as separate plates is used with especially good effect and several of the landscapes combine the highest artistic beauty with the greatest illustrative value. Several companion plates are very effective, for instance the field data of a complex area are presented on one plate and the completed map on an opposite plate. Again the tracings of thrust planes are given on a photograph of a mountainside and a section of the intricate geology of the mountain is given on a plate facing the first.

The chapter on metamorphism is brief. The Archæan is dismissed with a half page, and the line of treatment is not greatly influenced by the remarkable attempts to apply the laws of physical chemistry to the problem made by Van Hise, Grubenmann and Becke.

Then follows a chapter of fifty-four pages on geological surveying, which, as it is largely given up to the description of structural features, and, indeed, contains the only discus

sion of the glacial formation, offers only rather brief and general directions for field work."

T he economic aspects of geological structure are then taken up in a very detailed and interesting way, full of practical suggestions for the application of the ideas developed in the preceding chapters.

The book closes with a brief chapter of thirty pages covering the whole subject of denudation and the evolution of all the surface features of the earth, and there is no suggestion of the survey or special field study of these subjects. The contrast between the two books comes out strongly here. The American book devotes 355 pages to the work on air and water and 38 to structural geology. The other gives 30 pages to erosion and 166 to structure. The author shows a great and, in the main, wise conservatism in the employment of new terms. Peneplain does not appear, nor any of the superabundant and largely anthropomorphic terms used especially in America in the description of topographic forms and the cycle of their growth. At the same time he gives with brevity a clear description of the river cycle. The author is, perhaps, not quite consistent as he uses the new or rare word 'phacoids' for 'augen,' which is fully as bad as phenocryst. He seems to wish here to avoid the German, but in another connection uses lee-seite and stossseite, when lee-side and stoss-side are good English. In still another connection the word hornfelses has an unattractive look.

In this large book, given up almost entirely to the presentation of facts, the reviewer has wished to criticize only one minor statement. It is said (p. 51) “ Tachylite is altered to a yellowish or reddish substance known as Palagonite.” Palagonite is certainly an original volcanic glass which has cooled with its present large content of water. A certain uncertainty inherent in the subject may be noted in the treatment of amphibolite and hornblende schist. The two volumes thus supplement each other in a valuable way, the one being a full and well-considered hand-book for use in the sober work of geological surveying or economic investigation, in a country like Scotland, where there are no active volcanoes, earthquakes or glaciers; the other a bold and stimulating guide in every branch of research concerning the evolution of the earth.

The Students' Laboratory Manual of Physical Geography. By ALBERT PERRY BRIGIAM. New York, Appleton. 1904.

This is an expansion of the ‘Teachers' Guide and Laboratory Exercises’ published in 1903, and like it designed to accompany Gilbert and Brigham’s ‘Introduction to Physical Geography,' to which it is very closely adjusted. It is about half as large again as the Teachers' Guide,' but omits the lists of books. It is purely for the student and implies the additional use of the guide by the instructor.

Any one using the text referred to will find this an admirable guide for its illustration by map and exercise. It contains many suggest ive questions that must help the inexperienced teacher toward modern points of view. This is particularly true of the questions on map reading, which are good and abundant, as they ought to be. For class use they may need some selection apart from selection of exercises, if thorough work by the student himself is to be done. Thus the exercise numbered 13, contoured maps, has material for three one hour exercises with pupils in the 'early stages of the high-school course, if the reviewer's experience is to be trusted. Drawing a section for the first time, for instance, is no side issue, but quite a task in itself. Alongside this exercise 263b, C. S. Chart No. 3,089 is wonderfully short and easy, though for students well advanced toward the end of their course. The practical exercises are still further from definite form. It would be a hardship to put this book into the hands of the ordinary teacher of the subject, who is almost invariably too crowded for time and too incompetent in the subject matter to rearrange the exercises in practical form, and require her to use it with her classes. No doubt the class would get advantage of it.

It might be supposed that the wide use of laboratory manuals for physics and chemistry

might guide us in some measure in preparing one for physical geography. Many of these are models in their clear statement of what materials to use, what to do with them and how to do it. This definiteness is of great importance. First-year pupils in a high school will find the latitude exercise in this volume, with its generalities, its principle, its geometry and trigonometry, very discouraging.

The description of field exercises for use in unknown localities has generality and vagueness imposed on it by necessity. It is difficult to conceive of satisfactory accounts being written for such work: Professor Brigham has gathered together some excellent suggestions, and that is all that can be done. The variety of the local fields forbids adequate general treatment. The point of view of the work is modern and scientific, as would be expected of its author. Teachers will find it a safe guide to open their eyes and those of their pupils to the real world about them. Altogether we are left still awaiting an adequate laboratory manual for physical geography, but in the present volume is much material that ought to figure in the book when it is written, much material that ought to be in the hands of teachers attempting laboratory work or wishing to know how to do it.

Elements of Applied Microscopy. A Text

book for Beginners. By CHARLES-EDWARD Amory Winslow, Instructor in Industrial Microscopy and Sanitary Biology in the Massachusetts Institute of Technology. Pp. 183, with 60 text figures. New York, John Wiley and Sons. 1905.

This manual is an excellent example of a book prepared for a definite purpose and as the result of experience in an institution where independent work and special ideas have a prominent place.

As the author states in his preface the book does not profess to compete, on the one hand, with monographs or on the other with the popular works on microscopy. It is, however, specifically intended for the class in industrial

microscopy for second year students in chemistry and biology at the Massachusetts Institute of Technology. The object of the course is to give facility in the manipulation of the microscope and an acquaintance with the scope of its practical application.

The first four chapters consider the microscope and its accessories, and the other eight chapters deal with the starches, adulterations of food and drugs, textile fibers, paper, medicine and sanitation, forensic microscopy, microchemistry, petrology and metallurgy.

Each subject is dealt with in a general manner to give the student the principles and the point of view. Exercises are then given to illustrate the methods necessary for the elucidation of the questions which arise in actual practise.

The book is well conceived and satisfactorily worked out. The statements are usually clear and concise. As planned by the author, it is an introduction to the subject, and was designed for use by a teacher possessing knowledge of the more elaborate books, and the monographs bearing upon the various subjects. For the student, excellent references to good sources for further information are given with each chapter so that those espe, cially interested can follow out the subject.

It is not particularly adapted for private learners, as the directions are frequently too brief without the supplementary instruction which naturally goes with a laboratory course. Two directions would prove unsatisfactory in practise: On page 41 the student is told to transfer cover-glasses from the potassium dichromate, sulfuric acid cleaning mixture to fifty per cent. alcohol. After a thorough rinsing in clean water, should have been added. On page 28 under the directions for using the Abbe condenser, it is said: 'In general an opening [of the diaphragm] about the size of the front lens of the objective will yield good results. While this applies to lighting, when no condenser is used it would lead one to light with a less aperture when using an oil immersion objective than when using a low power dry objective. It contravenes the principles given in the preceding chapter. These and a few other slips will be

The Structure and Development of Mosses

and Ferns (Archegoniates). By DOUGLAS HOUGHTON CAMPBELL, Ph.D., Professor of Botany in the Leland Stanford Junior University. New York, The Macmillan Company; London, Macmillan & Co., Ltd. 1905. All rights reserved. Pp. vii + 657. 8vo.

It is but a little more than ten years since the first edition of this book appeared, and now we have a second and considerably revised edition, in which much new matter has been added. By an odd oversight, the fact that this is a second edition is not indicated on the title page, although it is clearly stated in the ‘Preface to the Second Edition' with which the volume opens. In this revision, the whole book has been printed from new type, none of the old stereotype plates having been used. This has given the author as much freedom in the preparation of the present book as though it were wholly new, and he has not been obliged to confine his changes to such as could be made to conform to the limitations of the old plates. The result is that this is a new book, and while it resembles the earlier one, and contains much matter which was in that edition, there is scarcely a page or paragraph in which the author has not made some changes of greater or less importance.

The new book follows the same general sequence as the old one, and, on a cursory glance, the reader sees little difference, yet a closer examination shows many changes and additions. The more important changes are those in the treatment of Marattiales, Isoetaceae and Lycopodinae. In the old edition, the Isoetaceae were discussed in connection with the Marattiales, to which they were regarded as related, but in the new book we find them taken up after the Lycopodinae, being regarded as "sufficiently distinct to warrant the establishment of a separate order, Isoetales.'.
