The Metamorphoses of Man and the Lower Animals. By 
A. de Quarreraces, Membre de Il’Institut, Professeur 
-au Muséum d’Histoire Naturelle de Paris. Translated 
by Henry Lawson, M.D. 
M. de QuarreraGzEs stands unquestionably in the first rank 
of French naturalists. His researches on;the embryology of 
mollusca, on the anatomy of Annelida and numerous other 
contributions to zoological science have gained for him a wide 
reputation. In the small octavo volume before us he has 
under the title of ‘ the Metamorphoses of Man and the Lower 
Animals,’ grouped together the latest researches and conclu- 
sions of comparative anatomists on the various phenomena of 
reproduction and development ; from these he draws his own 
deductions and generalisations ; the whole being treated in a 
most pleasant and readable style, and in a manner which, con- 
sidering the abstruse though interesting nature of the facts 
dealt with, should ensure the popularity of the work among 
scientific readers. 
It is not, however, as a mere compiler that the author 
comes before us. The first contribution of this distinguished 
naturalist to science was a paper on the larval forms of 
Anodon, and his subsequent researches on the development of 
Hermella and Teredo are well known, as also other essays on 
subjects connected with the much vexed questions of partheno- 
genesis and agamic reproduction. The conclusions, therefore, 
which the author draws at the end of his book are most 
worthy of the serious consideration of men of science, and 
they will doubtless carry the weight with them, to which M. 
de Quatrefages’ name entitles any opinion which he may 
express. 
The title of the work is somewhat inappropriate, as it would 
lead the reader to suppose that a certain amount of space is 
devoted to the consideration of the growth of man and the 
modifications of structure attendant on his progress from
