various anatomical details, and six plates crowded with figures of the moths 
themselves, which, although not coloured are very nicely drawn and 
characteristic. 
SCIENCE MANUALS.* 
T70LL0WING the example of some other publishers Messrs. Chambers 
have commenced a series of “ Elementary Science Manuals ” intended 
to serve the two purposes of self-instructicn and school-teaching. The 
manuals already published include Geology and Historical Geology, by Mr. 
James Gikie ; Astronomy by Dr. Findlater, who is the general editor of the 
series ; Electricity by Mr. John Cook ; Chemistry by Dr. Crum Brown ; Lan- 
guage by Dr. Findlater; and Mythology by Mr. A. S. Murray, of the 
British Museum. The names of these authors are of themselves a sufficient 
guarantee that the work is’ creditably done, and an inspection of the text 
shows that they have really succeeded in compressing into these very small 
volumes an astonishing amount of good and well-selected information. It 
seems to us, however, that some of them are rather sanguine if they expect 
the scholar after studying the manuals to answer some of the examination 
questions that they have appended to them. 
PAGE’S GEOLOGICAL TEXT-BOOK.f 
B P. PAGE’S “Advanced Text-Book of Geology ” is so well known that 
we need do little more than announce the appearance of its sixth 
edition. Naturally there is little or no change in the general treatment of 
the subject, but the author appears to have carefully worked in the results 
of recent investigations, where these come within the scope of his work, and 
he has introduced a considerable amount of additional information without 
materially increasing the size of the book, by placing the new matter in 
small type. Several new illustrations have been inserted.

T HIS little book is a synopsis of the vertebrata of the northern parts of 
the United States, and it ought to prove an exceedingly useful manual 
for residents and travellers in the region of the zoology of which it treats.
