410 The American Naturalist. me 
Aside from some minor slips of no importance, our greatest criticism 
would be that the work goes too much into detail, calling the students 
attention as strongly to minute points without any morphological 
importance as to those facts more pregnant with meaning. of 
course, is a minor matter where the student has a good course of lect- 
ures to accompany the laboratory work. It would be even less object- 
ionable were there good text-books to assist him, but, as yet, the 
zoological text-book is a matter for the future. 
Excepting this matter of lack of perspective which the student will 
in most cases be troubled with, we like the work and we feel confident 
of its adoption in many schools.
