POPULAR SCIENCE REVIEW. 
THE DOCTRINE OF ENERGY.* 
M R. D. HEATH has attempted to write a hook which shall explain what 
is the nature of so-called energy, and how it is influenced by various 
conditions, extending so far even as physiology. Rut he has endeavoured to 
write such a book exclusively for boys of the class of the “ 6th form Boys of 
the Surrey County School.” In this we think he has completely failed. 
That he has the knowledge we do not deny for a moment ; but that he is 
capable of imparting it in such a popular form as Professor Tyndall or 
Professor Huxley would adopt, or indeed in a popular form at all, we very 
decidedly deny. The book is a good one, which may be read with ad- 
vantage by students who are preparing for the London University. But for 
schoolboys we certainly do not think it is at all well adapted. 
AUTOBIOGRAPHY OF DR. GRANVILLE.t 
mHIS not being a scientific work must be our only excuse for so short a 
J- notice. It is, in point of fact, not a book which should have come to 
us at all : still we cannot help saying that it has interested us so much 
dhat we were insensibly led on from page to page, till at length we deter- 
mined to read the two volumes of which it consists. And we have been 
intensely pleased with the life, for it is a sort of sketch of the politics of 
the time ; something, in fact, like a story of what Holland House must 
have been — a mixture of sociality and political matters of the most in- 
teresting character, and told in a brilliant, sparkling style. The work is 
one which those who are ignorant of the life of the last three quarters of a 
• century should read. Then they will see how much a man who was really 
an. Italian, though by association an Englishman, can be mixed up with 
the affairs of his century, though belonging to so humble a profession as that 
of medicine. Great credit is due to his daughter for the very laudable and 
vsomewhat reverential manner in which she has discharged her task of 
■editor.
