strata in the field, a subject which at the present day some other- 
wise excellent scientific men are attempting to depreciate. 
A second work by the same authors on engineering geology 
will soon be published. It purports to be a practical guide in the 
interpretation of those geological phenomena by which engineer- 
ing works, building materials and water supply are effected, and 
in the methods of surveying, by which such geological conditions 
are determined. 
SKETCHES OF THE PHYSICAL GEOGRAPHY AND GEOLOGY OF NE- 
BRASKA.'—This is one of the most interesting and valuable books 
yet published on the scientific and practical resources of the State 
of Nebraska. Prof. Aughey has been for many years a most 
months, already a second edition is called for. We congratulate 
Prof. Aughey on his well-deserved success. 
ARCHIVES OF COMPARATIVE MEDICINE AND SURGERY. — We 
note with interest the appearance of this new periodical. Its 
objects are divided between economic and pure science, so as to 
appeal to a larger constituency than if its scope were confined to 
either alone. We note various interesting statements of observa- 
tions on the pathology and anatomy of the lower animais, espe- 
cially of the Vertebrata. One of these, on the Island of Reil, we 
transfer to our notes. The Archives has a wide field, and, under 
its present able editor, we hope for its success.
