60 THE AMERICAN MONTHLY. [March 
gists. We believe that in its sphere the work is calculated to do what should be done 
for younger students, to open their eyes to facts, and teach them how to see and to see 
closely. Since the work is likely to come into use in colleges, we feel compelled to call . 
attention to one serious limitation of its value for this purpose. It is not full enough, and 
stops usually when it reaches the hard places. Thus in the description of the crayfish, 
the dissection of the ear and the fine dissection of the nervous system are omitted, also 
the entire omission of the green gland and of all direction for histological study may 
be noted. These omissions, arising out of consideration for the early and untrained 
powers of a too young pupil, are the ones best calculated to train and help the college 
student as well as to teach him zodlogy. The arrangement of the creatures studied is 
peculiar, and we hardly see upon what ground it is based, for it is apparently entirely 
hap-hazard. First come the arthropoda, then the molusca, in somewhat orderly fash- 
ion; following them protozoa, then vertebrates, then echinoderms, ccelenterates, and 
finally sponges. The work attempts but slightly to inculcate principles of classification, 
and herein itis right; but we think that little would be lost and much gained by taking 
the subjects in an order which is a somewhat nearer approach to the recognized sys- 
tematic arrangement. We must say one brief word by way of commendation to the 
genius who thought of placing the table of contents on the inside front-cover, and 
the index on the inside back-cover. This scheme makes these tables of the utmost 
accessibility, and, so far as we know, is an entirely novel plan.
