^ants to know and cannot easily learn elsewhere. It shows 

 how the specmiens should be studied, explains the appearance 

 -of their several parts, their structure, and their function as far as is 

 known. An exceedingly commendable feature is that in foot 

 notes the reader is told where he may find the subject treated 

 more extensively, so that he may make himself familiar with 

 the recent researches of English speaking entomologists, for most 

 of these references are to accessible literature in our own lan- 

 guage. The illustrations that really illustrate are numerous and 

 beautiful. 



Physiognomy and expression. By Paolo Mantegazza. 8vo., 

 pp. 224. New York : The Humboldt Pub. Co.— This book may 

 be read with satisfaction even by those that believe that physi- 

 ognomy is a kind of occult art possessed by few, and worthless 

 when those few attempt to explain its principles and to teach their 

 application. That there is a foundation of useful facts in the 

 vagaries of the advancing physiogoraist no one will be disposed 

 to deny, but that the thoughts of a man's soul and the condition 

 of his physical functions, are written on his face and in his eyes, 

 are claims to be laughed at. The author says that he has set 

 himself the task of separating positive observations from the 

 number of bad guesses and ingenious conjectures that have en- 

 cumbered the path of the study. " My wish has been to render 

 to science that which is due to science, and to imagination that 

 which is due to imagination." But after the imaginary parts 

 have been eliminated, science has but a sorry showing for her 

 5hare of the si3oils. Yet the book is interesting, and worth read- 

 ing for the sake of studying the extremes to which an unbridled 

 imagination can go. Many of the fantasies of former writers 

 Senator Mantegazza ridicules without mercy, and thereby makes 

 his book exceedingly suggestive.
