SATURDAY REVIEW.—“ Dr. Sharp’s treatment is altogether worthy of the 
series and of his own high scientific reputation. . But in a work of this sort it is 
not only necessary that information should be accurate; but also that it shall be 
presented to the eye, so far as illustrations and printing are concerned, in such a 
way as to render its matter as easily intelligible as possible, and readily usable 
for purposes of refesence. Under both these heads we have nothing but commenda- 
tion for Mr. Sharp’s treatise. The illustrations are indeed beautiful, and the use 
of the heavy type for the headings of the various sections and leading paragraphs 
materially helps the reader in the progress of his study. Certainly this is a book 
that should be in every entomologist’s library.” 
AMPHIBIA AND REPTILES

-By Hans Gapow, M.A., Ph.D., F.R.S. 
FIELD.—‘‘ The work is worthy of the series in which it appears, and we can- 
not give it higher praise.” ; 
SCIENCE GOSS/P.—‘‘ More than maintains the high scientific reputation of 
this series. The herpetologists, or students of the Amphibia and Reptiles, have now 
a standard work of the highest class.”
