CARPENTER, ON ZOOLOGY. 117 
The Microscope: its History, Construction, and Application. 
By Jasez Hoee. Third Edition. London: Routledge. 
Wuewn Mr. Hogg’s work first appeared, we predicted for 
it a large sale, on account of its excellent illustrations and 
low price. He tells us, in his preface to this, the third 
edition, that two editions, of five thousand each, have been 
sold, thus fulfillimg our prophecy. We know, also, that other 
works have been equally successful, affording a gratifying 
proot of the extended interest taken in microscopic researches. 
In this third edition, Mr. Hogg has taken the opportunity 
of adding much new matter, and bringing up the information 
it contains to the time of publication. 
Zoology ; being a systematic account of the General Structure, 
Habits, Instincts, and Uses of the principal families of the 
Animal Kingdom. By W. B. Carpenter, M.D. Vol. I. 
A new Edition, edited by W. S. Datuas. London: 
Bohn. 
WE call attention to this new and cheap edition of Dr. 
Carpenter’s work on Zoology. It is now published in Mr. 
Bohn’s series of standard scientific works, and has been 
brought up to the present requirements of the science of 
zoology by the aid of Mr. Dallas, whose scientific labours as 
a zoologist are well known.
