POPULAR SCIENCE REVIEW. 
THE SCIENCE OF HEAT.* 
T HIS excellent little manual was, through some oversight, left unnoticed in 
our last Number. It is clear, well written, and up to the date of modern 
discovery, and is so arranged as to he easily mastered by the intelligent 
student. The book is divided into three portions : in the first are described 
the various effects produced upon bodies by heat ; the second contains the 
laws which regulate the distribution of heat through space ; and the third 
relates to the nature of heat, its sources and its connection with other pro- 
perties of matter. Mr. Stewart is one of our highest authorities on the 
subject of heat, and this fact alone should insure the success of his manual ; 
but the book carries with it intrinsic elements of success ; for it contains 
exactly what the University-student wants, and it is so arranged that the 
reader is led to take an interest in the phenomena of heat before being in- 
troduced to the complex laws which govern them. 
Chemical Philosophy according to Modern Theories , by Dr. Adolphus C. 
Wurtz, F.R.S., translated by W. Crookes, F.R.S. London : Dutton. 1867. 
We could not possibly review this work in our columns, for it is such an 
advanced dissertation upon the modern philosophy of chemistry, that, even 
if we had the space at our disposal, the treatment of the subject would be 
too technical for our pages. We remember with pleasure seeing the lectures 
of Dr. Wurtz published in the Chemical News , and we congratulate the able 
editor of that journal upon his selection of the lectures, and on the ability 
with which he conducted the translation. The book is small, but it contains 
an able exposee of the modern theories ; and we confess, with its translator, 
that for breadth of view, lucidity of expression, orderly arrangement of facts, 
and shrewdness and fairness in reasoning, Dr. Wurtz’s treatise appears to be 
singularly distinguished. 
The Inductor ium, or Induction Coil, fyc., by Henry M. Noad, Ph.D., F.R.S. 
Second edition. London : Churchill. 1867. We direct notice to this, a 
second edition of Dr. Noad’s instructive little work on the induction coil. 
Those who are anxious to get an insight without much trouble into the 
wonderful phenomena connected with the operation of the induction coil 
should purchase this book. 
The Year-Book of Facts in Science and Art , by John Timbs, F.S.A. 
London: Lockwood. 1867. This little volume is a resume of scientific 
progress during the past year. The difficulties of such a compilation render 
mistakes inevitable, but Mr. Timbs’s summary is more accurate than its 
class generally is. The cuttings are principally from the Illustrated London 
Neivs and Mechanics' Magazine. 
The Twin Records of Creation , or Geology and Genesis, by Geo. W. Victor 
Le Vaux. London : Lockwood. 1867. Adopting the extremely novel 
* u Elementary Treatise on Heat.” By Balfour Stewart, LL.D. Oxford : 
at the Clarendon Press, 1866.
