262 The American Geologist. April, isat 
The author has succeeded in making an attractive grouping and 
presentation, in simple and plain English phrase, of the whole scheme 
of modern geomorphy. It is necessarily synoptical. It does not 
abound in illustration, but its principles are enforced as well as illus- 
trated by reference to well-known geographic and topographic fea- 
tures. The field to which the author specially directs attention is Eu- 
rope, and for the European student the discussions must come home 
with great force. A similar treatment of American phenomena of the 
same kind is now in order. 
The book of Prof. Russell is more special, both in its intent and its 
execution. The philosophy of river action, and the processes by which 
its progressive unfolding is illustrated in the degradation of the land 
and the final production of peneplains, are given in much detail. In- 
deed the detail becomes almost prolix and the descriptions tautological, 
when the process is presente'd from points of view which differ but 
slightly. The whole book is summarized in a single chapter (ix) which 
amply describes the "life history of a river." For a trained physio- 
graphist, or for an adult student who has had some training in nature's 
operations on the surface of the earth, this chapter is sufficient. At the 
same time it is elegantly written^ and is even poetic in its generalized 
descriptions. The body of the book will serve as a guide in class- 
room work, or as an accompaniment to a course of lectures. 
This work is strictly an American product, as it is based on Ameri- 
can phenomena, and frequently cites American geographers. It is 
well illustrated with good half-tone views of actual scenes.

Studies on Cambrian Faunas. No. 2, by G. F. Matthew. (Trans. 
Roy. Soc. Can. 2d sen Vol. IV, sec. IV, p. 123.) 
In this paper is described the Cambrian System in the Kennebecasis 
valley in New Brunswick, Canada, and its faunas. 
In the first part of the paper the stratigraphy of the Cambrian rocks 
in this valley is set forth and there is a sketch map showing the several 
areas of Cambrian rocks, which are very limited. The Etcheminian se- 
ries which lies between the Cambrian and Huronian (Coldbrook) in the 
St. John basin is wanting in this valley; and the Cambrian deposits herr 
are much thinner than in the St. John basin. 
The second part of the paper refers to the fossils found in the Cam- 
brian rocks of the Kennebecasis valley. These are chiefly of three hor- 
izons, viz: (a) That of the Protolenus fauna of the St, John basin; (b) 
The Paradoxides-Dorypvge sub-fauna ("Upper Paradoxides beds" of 
Sweden); and (c) A fauna of the Upper Cambrian, characterized by 
Anoniocare stenotoides. 
In connection with the Protolenus fauna a remarkable brachiopod 
(already described in the Geological Magazine, London) is redescribed 
with further particulars in reference to some trilobites, and some new 
species of ostracods are described. 
The sub-fauna of Paradoxides-Dorypvge is only alluded to here, it
