POPULAR SCIENCE REVIEW. 
In the present edition we perceive that many new features have been intro- 
duced, and that the hook has been considerably enlarged. Dealing as it does 
with the construction of the different varieties of telegraph, and with the 
most approved means of constructing lines and supplying galvanic force, it 
is a work which must be especially valuable to electric enquirers and tele- 
graph superintendents. It will be found the textbook of reference, indeed 
the only one, on its subject. 
Beliquce Aquitanicce , Contributions to the Archceology and Palceontology oj 
Perigord. By Edouard Lartet and Henry Christy. Part IV. London : Bailliere. 
1867. — This number reached us too late for notice in our last issue. Like 
the former, it is edited by Professor Rupert Jones. It continues the subject 
dealt with in No. III., and treats also of the geology of Vezere. The wood- 
cuts in the text are good, and the plates, six in number, are admirable works 
of art. They are brought out in Paris by Louveau and Becquet, and surpass 
in excellence illustrations produced in this country. 
The American Naturalist. Essex Institute, Salem, U.S.A. — Of this 
monthly periodical we have received the numbers from March to August, 
with the exception of that for May. It is a new venture, devoted to the 
interests of General Natural History, and is creditable alike to its editor and 
publisher. The papers, though not upon strikingly original questions, are of 
much popular interest, and are, we perceive, written with a due avoidance 
of technicalities. The illustrations to the paper on Polyzoa and Jelly-fishes 
are accurately and artistically executed ; the plate accompanying Dr. 
Packard’s article on the Dragonfly being a perfect type of Natural History 
drawing. The reviews are written with care, and display a thorough im- 
partiality. We welcome our new contemporary, and we hope to profit by 
his gleanings from the vast American fields of Natural Science. 
Clinical Lectures on Diseases of the Skin. By Balmanno Squire, M.B., 
F.L.S. London : Churchill. 1867. — Mr. Squire is issuing a new and larger 
edition of his valuable photographs of skin diseases. The work will be com- 
pleted in thirty- six monthly parts, and the first four numbers are now before us. 
Each photograph is coloured, and refers to a particular case, typical of the 
disease it represents, and is accompanied by two pages of letterpress, which 
give the clinical history of the affection. For ourselves, we are dis- 
posed to think that the uncoloured photograph is more useful than the 
coloured one, and infinitely more reliable, but doubtless on this point we 
are at issue with most dermatologists. The series is, in any case, most 
creditable to the author, and will be equally servicable to the physician.
