philosophical anatomy in America. And third, these papers are 
absolutely free from covert flings and sarcasms at opposing theo- 
ries, and their author has done ample justice to the labors of those 
whose works he has employed; we must regret the lack of refer- 
ence to other, and later papers upon limb-homologies, especially 
those in the ‘Journal of Anatomy and Physiology.” But this was 
to some extent unavoidable with one who is serving in the army, 
and is at least atoned for in one way by the assiduity with which 
the author has made dissections of animals which he could pro- 
cure, * 
This hasty notice has done scant justice to Dr. Coues’s work. 
Let us urge upon all, who are, or wish to be interested in the study 
of homology, to read this series of papers; we hope before long 
to publish elsewhere + a more complete review of these productions 
of our morphological brother; to include therewith a notice of 
the remarkable paper of Professor Wyman, who is in limb-homol- 
ogies our common progenitor ; .to add some suggestions respecting 
terminology as to both the objects of our study, and the ideas in- 
volved therein; to indicate as far as possible, the various minor 
problems which will occupy us for the half century prior to the 
probable acceptance of these views by all anatomists ; and finally, 
to append a list of all works and papers bearing upon the question 
of the homology of the anterior and posterior limbs of vertebrate 
animals. —B. G. WILDER. 
Forms or Anima Lire. t{—In its plan, arrangement, and the 
great mass of details and its useful illustrations, this work on com» 
parative anatomy, is the most convenient manual we now have in 
the English language. Were we going away from libraries, for a 
sojourn by the sea-side to pursue anatomical studies, we sho 
take with us Gegenbaur’s incomparable “ Grunziige der Vergleich- 
enden Anatomie” (Principles of Comparative Anatomy), Huxley’ 7 
‘Introduction to the Classification of Animals,” and his “ Ele- 
mentary Lessons in Physiology,” but if deprived of these, and , 
one book was to do the work of all, our choice would be Professor 
Rolleston’s excellent compendium.
