Two Text-Books of Physiology.’—The State of Indiana has 
gone into the business of loaning its name as endorsing certain text- 
books, which are published as the * Indiana State Series." "These two 
books, by Professor Jenkins, now of the Leland Stanford University, 
belong to the series. Of the advantages and disadvantages of such a 
course, much might be said; but for this we have no room aside from 
the remark that in our opinion the disadvantages far outweigh the 
greatest advantages gained—the publication of the books at reasonable 
rates, the prices of the two volumes being fixed by law at thirty and 
sixty cents respectively. 
r. Jenkins has done his work well in both volumes, the *Advanced" 
work being the better of the two—the “ Primary " being too old in its 
style for the students for which it is intended. In each work there is 
a freshness of style and a logical arrangement which please us, and the 
greatest fault we can find with the work is the insertion of * review 
questions" which were doubtless demanded by the publishers (we 
might say parenthetically that Professor Martin’s otherwise excellent 
“Human Body, Briefer Course,” is damaged by the same operation.) 
Especially admirable is the treatment of the use of alcoholic stimulants, 
narcotics, and the like. There is no lurid description of the drunkard’s 
stomach, no intemperate use of adjectives, but rather a plain, common- 
sense view of the matter which will be as effective as the more extrava- 
gant statements so common in the suppression of intemperance. In short, 
we regard these books as among tbe very best for schools of the gram- j 
mar and high school grades, and ean but wish that they might sup- 
plant, in other States than Indiana, the trashy works so commonly in 
use. 
Calderwood on Mental Evolution.’—This octavo of 350 pages 
is written with the object of harmonizing the modern doctrine of evo- 
lution or physical continuity, with the doctrine of non-continuity of 
mental evolution, so far as regards man. The author endeavors to 
show that while the physical structure of man may have been the 
result of an evolutionary process, his mind presents too great a differ-
