book as one that will he read with much interest, and in conclusion can only 
express our gratification that its success has already been such as to warrant 
his expanding his original little volume to its present form, in which it is 
what our French friends would call a veritable ouvrage de luxe. 
NICHOLSON’S MANUAL OF ZOOLOGY.* 
TTTE have much pleasure in calling attention to the publication of a fifth 
* » edition of this excellent manual. It is, perhaps, the best exponent of 
modern non-Haeckelian views on zoological classification that we possess in 
English; and in the present edition, which is considerably enlarged, the 
author has been enabled to insert a good many more details as to the habits 
of animals and their relations to each other than were to be found in former 
issues, which might be regarded rather as giving the dry bones of animal mor- 
phology, than as expositions of the science of animals as they u live and move 
and have their being.” Much room for improvement in this respect no doubt 
still remains, but unless the book could be at least doubled in size, it would 
hardly be possible to give a satisfactory zoology embracing as much of 
structural detail as the present work. As a manual for students, which is 
what it professes to be, Professor Nicholson’s book is exceedingly good. 
This fifth edition does not differ in any important particulars from its pre- 
decessors, as regards the general treatment of the subject. The classification 
adopted is the same, with some slight exceptions, where groups of recent 
establishment have been accepted ; but the treatment is much fuller, and 
the results of very recent researches have been worked in, the additions 
being even more extensive than would appear from the increased number of 
pages, seeing that the author has adopted the device of printing a good deal 
of matter of subordinate importance in small-type paragraphs. 
Another new feature in the book is the suppression of the synoptical 
tables of families which appeared in former editions and the substitution for 
them of class bibliographies, which, if in some instances rather defective, 
will nevertheless prove useful to the student by indicating the main directions 
in which his further studies may be profitably pursued. This edition, which 
has many new illustrations, worthily maintains the reputation acquired by 
its predecessors.

T HE object of the writer is to prove that there are no traces of Man having 
existed before or during the so-called Glacial Period — that this Period 
occurred at no considerable distance of time ago — and that Man was intro-
