RECOMMEiNDATORY NOTICES. 



it has been justly observed, that " the double effect of the study f I\ f atural TIL'toi jr 

 IB to impart certainty to the mind, and religion to the heart," and the Christian no les 

 than the man of science, must rejoice in every effort to throw more widely open the 

 sublime and boundless field which it presents. Tins is the design of Dr. Ruschenberger, 

 in a series of First Books of Natural History, which he is preparing foi the use of 

 schools and colleges. Banner of the Cross. 



The series have i/iet a demand and sale in France almost unparalleled, and the words 

 are well adapted, not only for schools, but for popular reading and instruction. Thia 

 work is from the French of Edwards and Comte, and has received the warm commen- 

 dation of many of the best physicians and scholars in this country JV". Y. Eve. Tattler. 



It is highly commended by the very best authorities. JV*. Y. Tribune. 



This book is highly commended by competent judges, and we therefore give our so- 

 lemn opinion that it is an excellent work. Boston Daily Times. 



A small, but very valuable work. Boston Evening Transcript. 



We have examined this new book for schools and colleges, with peculiar gratification. 

 The style is succinct and clear, and the subject illustrated by appropriate drawings. We 

 tliould be glad to see this work introduced into all the schools. It teaches knowledge 

 Ihe most important, which has been, however, strangely overlooked in our school and 

 college system. It is a book which should not be confined to seminaries alone It may 

 be used with advantage by all individuals in society. We repeat, it is in all respects a 

 most excellent work, and we hope will receive the attention and patronage it merits. 

 Brooklyn Evening Star. 



A valuable work; we have read it with profit. JV". Y. Mercury. 



We are highly pleased with this work. For elementary instruction in families, 

 schools, and colleges, it is decidedly superior to any thing of the kind we have seen. It 

 gives much valuable information in a very small space, and in style it is generally free 

 from obstruse technicalities It has already received the highest recommendations from 

 a large number of professional men in different parts of the country ; and it must have, 

 we think, a general circulation. It gives that kind of knowledge which should be dif. 

 fused among the mass of the people, and it must and will be patronised as far as its 

 merits are known. Zion's Watr.hm.an. 



This is a fine little book, containing the elements of much useful learning, illustra- 

 ted by anatomical plates of the human figure, its organs and (heir functions. It is a 

 highly useful work to the student indeed to every citizen it shows how fearfully and 

 wonderfully we are made, and what slight causes may derange and utterly destroy lite 

 complicated machine. The Olive Branch 



A very useful little work. JV. Y. dtlas. 



As far as we are competent to determine, it may safely be welcomed as an important 

 addition to the means of elementary instruction in natural science, The Friend. 



We recommend it as a highly instructive publication. JV". Y. Times and Eve. Star. 



This is a most valuable work, by Dr. Ruschenberger, and most admirably are the 

 plates, representing all the different parts of the body, done. It is cheap, and every pa 

 rent should place one in the hands of their children. JV". Y. Herald. 



We have examined this little volume with much pleasure, and think it admirably 

 adapted to the purpose for which it is intended. Animal Mechanism, as a study, has 

 generally been neglected, except by the few, whose profession requires a knowledge of 

 it, and who have time to spare in acquiring that knowledge. A prominent cause of 

 the neglect of this useful and interesting science by the general student, is, the want 

 of a suitable treatise upon the subject, those extant being too voluminous, technical, 

 and expensive for general use. The little work before us is happily calculated to sup- 

 ply this want. It will, we think, be introduced into our schools and colleges as a text- 

 book, but its circulation ought not to be confined there. Every private library should 

 be considered incomplete without it. JV". Y. Mechanic. 



It seems to us to be well suited for the object for which it is designed, and it witi 

 doubtless be introduced into many of our elemer \ary schools. The American Juurn4 

 of Uie Medical Sciences.
