POPULAE SCIENCE EEVIEW. 
HANDY BOOK OF BOOK NAMES.* 
T his will prove, we do not doubt, a very useful little book to all practical 
geologists, and also to the reading student of rocks. When a ^fficulty 
is incurred as to a species of deposit, it will soon vanish. Mr. Kinahan’g 
little book will soon make it all clear. The work is divided into three 
parts. The first is a classified] table of rocks, the second part treats of 
the Ingenite rocks, and the third part deals with those rocks which are 
styled Derivate. Dana’s termination of yte has been most generally used 
by the author, but he has also given the ite terminations for those that like 
them. Mr. Kinahan gives the following direction : — A student wishing to 
have the description of a rock must first look for the name in the index, and 
if the name does not occur there, it will be found in the classified list in its 
proper group, class, and order ; he must then refer for the description to 
either Part II. or HI. The book will be purchased, for it must be had, by 
every geologist ; and as its size is small, it will form a convenient pocket 
companion for the man who works over field and quarry. We fancy that 
the late John H. Kinahan had the idea of this book in his head some time 
before he died : at least, the writer has heard him say he wished much for 
such a work. 
EELIQUI^ AQUITANIC^.t 
A fter a long lapse of time another Part ” of this well-known and 
well got up volume has at length appeared ; and with it has come a 
promise from the editor — Prof. Rupert Jones, F.R.S. — that it will now go on 
to completion, though not so far as had doubtless been intended by the dis- 
tinguished co-author, Mr. Henry Christy. Still it is, we think, well that it 
should be completed notwithstanding the death of M. Edouard Lartet, 
which produced the last cessation. It is now somewhere about two years 
since M. Lartet died, and during that time no part has been issued. Now 
that it has begun to reappear, the editor promises that he will lose no time 
over it, and hence we may probably assume that it will not be long till it is 
completed. Meantime the part that has appeared is in no measure inferior 
to any that have preceded it, but in point of matter, and especially in plates, 
is fully equal to its predecessors. The remarks on the reindeer are full of in- 
terest, and the classical knowledge of the author is brought to good account 
in explaining the gTeat change of climate which Rome has undergone even 
in historic times. This part also includes a letter [Dec. 10, 1870] from 
A. C. Anderson, Esq., of Vancouver’s Island, on the assumed co-existence of 
the reindeer and the hippopotamus, in which he expresses very fairly and 
clearly an adverse opinion to that held by M. Lartet. Altogether this 
Part ” is very good, and gives excellent promise for its successors.
