120 THE AMERICAN MONTHLY. [November. 
sented to us the most valuable text-book of embryology which has appeared since 
Balfour's Comparative Embryology. . 
The work is brought down to include even the latest information on all matters. 
Thus, in the account of the foetal membranes of mammals and their origin, the results 
of the very recent researches of H. F. Osborn and Caldwell, which contain important 
additions to our former information, are summarized. But while the writer deals 
largely with fact, so far as it is settled what fact is, he is not dogmatic, nor does he fail 
to impress on his readers the important idea that embryology is not a dead science 
with all its parts stiff, rigid, and fixed; on the contrary, he gives sufficient scope to the 
speculative element in embryology, so characteristic of a young and growing depart- 
ment of science. By the device of introducing such matter in a finer type, it is sorted 
for the benefit of those readers who do not care to follow the theoretical aspects of 
questions. He has also a chapter at the close of the book wholly devoted to the con- 
sideration of general questions. To add to the usefulness of the work the indexer 
and bibliographer have performed their parts admirably. 
It would be a pleasure to follow the author more into detail, but this our space will 
not permit. The figures employed to help out the meaning of the text are excellent, 
selected from a great variety of sources, and well copied; they clearly show the point to 
be illustrated. The work will be desired by all working embryologists, but should be 
brought to the notice of all medical students, for whom it is especially designed. We 
should be glad to see its introduction upon the works of reference and study in all 
medical colleges, and to find it in the library of every live practitioner. ‘ 
Intermediate Anatomy, Physiology, and Hygiene. By John C. Cutter. Philadelphia. 
J. B. Lippincott & Co. 1887. (pp. 221, figs. 69). 
Twenty years ago no treatise on human physiology was better known than Cutter’s 
‘Anatomy, Physiology, and Hygiene.’ Its disuse of late has arisen from the fact that 
it was not revise . and renovated to keep pace with the immense recent advances of 
the science. It is fortunate for the cause of elementary instruction in this department 
that a son of the elder Cutter has followed in his father’s track, learned the practice 
of medicine, and attempted to place before the school world an elementary work on 
physiology, which is written by one who knows the subject and can avoid telling too 
much. A high school student will learn much from the work, and what he learns will 
be useful and a foundation for later studies. To meet the demand for physiological 
text-books which treat of the harm to the body from stimulants in general and alcohol 
in particular, the reviser has added to the hygienic part of the old editions special 
paragraphs upon alcohol, tea, coffee, etc., which occupy due prominence and are clear 
and intelligible, not a mere meaningless rant on the harm without stating wherein the 
harm lies. Each function, as it is described with the organs which serve it, is consid- 
ered separately as to its hygiene or healthy operation, and as to the common practices 
which interfere with its healthy working.
