528 Notices of Books. [October, 
volume. In an appendix the Author gives the addresses of Profs. 
Barnard, Draper, and White, on the occasion of his departure 
from America, and the preface of the French translator of his 
work (the Abbé Moigno). 
Natural Philosophy for General Readers and Young People. 
Translated and Edited from Ganot’s Cours Elémentaire de 
Physique. By E. Arxinson, Ph.D., F.C.S., Professor of 
Experimental Science in the Staff College. Second Edition. 
London: Longmans and Co. 1875. 
Tuis is an abridgment of the well-known larger work of Ganot 
on the ‘“‘ Elements of Physics.” It is divested of mathematical 
formule, and is. specially adapted for young persons and for 
science classes in schools. The extent of its subject-matter may 
be defined by the fact that it represents the amount of physical 
knowledge necessary for the matriculation examination of the 
University of London. We are glad to notice a second edition of 
the work, because we believe it to be a really useful work ; but we 
regret to notice that many clerical, and a few other, errors have 
not been expunged from the first edition. ‘These will, however, 
be at once apparent to the teacher, and can be corrected by the 
student once for all. A second coloured plate has been added 
to this Edition, together with twenty-four new woodcuts, and 
twenty pages of new matter; the editor has also not contented 
himself with giving a mere literal translation of the French 
work, but has made various additions in order to render it more 
complete. We would suggest that in the next edition a number 
of well-selected questions on each chapter of the work be given, 
specially some questions of an arithmetical character (in regard to 
levers, the inclined plane, the laws of falling bodies, and of the 
pendulum), which are much affected now-a-days in the London 
Matriculation and other examinations. 
A Short Manual of Heat, for the Use of Schools and Science 
Classes. By the Rev. A. Irvine, B.A., B:Se.> ongear 
Longmans and Co. 1875. 
An Elementary Book on Heat. By J. E. Gorpon, B.A. In- 
tended chiefly for the use of Candidates for the General 
Examination for the Ordinary B.A. Degree. London: Mac- 
millan and Co. 1875. 
Ir is surprising that with such a book as Prof. Clerk Maxwell’s 
‘“‘ Elements of Heat,’”’ and the Clarendon Press Manual of Prof. 
Balfour Stewart, there should be room for any other elementary 
work on the subject; yet we have here two little treatises appear- 
ing within a very few months of each other. The first is by
