OPINION OF THE PUBLIC PRESS. 



" Such a little treatise is just the thing for our schools and academies and 

 no time should be lost in introducing it." — Neic York Mirror. 



" This is a most excellent work, and we would most respectfully recom- 

 mend it to our common school tru-tees, as worthy of introduction into tlie 

 temples of learning under their supervision." — Xew York Xeic Era. 



"The plan and arrangement of the work are admirable, and eminently 

 culculated to facilitate the progress of the pupil. — We recommend it to 

 te-achers and Iieads of families." — Philadelphia Sat. Chronicle. 



" We know of nu books better calculated to convey elementary instruction 

 than these, and heartily recommend the two which have appeared."— J5fOi/(er 

 Jonathan. 



"We cannot tooearneslly recomniind it to public attention." — Cincinnati 

 Enquirer. 



" Decidedly one of the best elementary works on the subject with which 

 we have ever met." — New York Lancet. 



"The information it contains is at once lucid, intelligible, and satisfactory; 

 it forms an excellent text-book for classes in schools, and cannot fail to 

 infuse into the young mind a knowledge and love of Natural History. It 

 is concise and comprehensive, and must if adopted in seminaries of learning, 

 he exceedingly useful in inculcating a correct knowledge of the elements of 

 Zoology. The plan is excellent, and must be found eminently useful." — 

 Alexandria Gazette. 



" It is one of the most valuable works of the kind we have ever read. — 

 Such are the books we like to see disseminated among the people." — Xew 

 Orleans American. 



"The reputation of the author is a guarantee that the work is a good one. 

 On examination we find it to be so. It is an admirable compend of the 

 subjects of which it treats: — we should think, indeed, that it would attract 

 the attention of teachers, both from its cheapness, and the admirable manner 

 in which it is arranged." — Cincinnati Gazette. 



" The Second Book: — this number treats of all animals that in infancy 

 feed on the milk of their mothers; from the human being down to the mus. 

 quito-catching bat. — Like the " First Book," it is divided into questions and 

 answers, and a glossary ; and is illustrated by six plates. It is as cheap as 

 dirt ; and contains an abundance of useful information. There are thousands 

 of persons in this country, and millions in Europe, who do not know that 

 whales give milk." — Xew York Era. 



"We do not know a more useful set than this promises to be: — and IS." — 

 New York Aurora. 



"We hesitate not to say that it is a valuable work, and fully entitled to 

 the high encomiums bestowed upon it ; taken as a whole the work may be 

 justly regarded as invaluable to schools." — Xew York Standard. 



" It is a most valuable work, and one which we believe has no superior in 

 our seminaries, — we know of notliin^ equal to it. It is very flatteringly 

 recommended by the most distinguished men in France and in the United 

 States, and deserves it." — Xew York Courier and Enquirer. 



Ruschenherger^s Second-Book of Xaiural History. — " This is another of 

 those useful volumes, which Dr. Ruschenberger is so beneficially in editing. 

 His former volume has already been received into some of our public school^, 

 and we hope both it and the present may find their way into all." — American 

 Medical Intelligencer. 



The present work, is in our opinion quite a desideratum, and abounds 

 with information of the most useful and, at the same time, most necessary 

 character, every parent should place it in the hands of his children, and no 

 -pubhc instructor should neglect to give it a place in his academy. — Phila- 

 delphia Spirit of the Times.
