OPINION OF THE PUBLIC PRESS. 



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

 no titne should be lost in introducing it." — New York Mirror. 



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

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

 temples of learning under Iheir supervision." — New York New Era. 



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

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

 teachers and head-; of families." — Philadelphia Sat. Chronicle. 



" We know of no books better calculated to convey elementary instruction 

 than these, and heartily recommnd those which have appeared." — Brother 

 Jonathan. 



"We cannot too earnestly recommend 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 ex?cllent 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 -ind compiehensive, and must if adopted in seminaries of learning, 

 be exceedingly useful in inculcatng a correct knowledge of tiie elements of 

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

 Alexa ndria Gazette. 



" It is one of the mo.*t valuable works of the kind we have ever read. — - 

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

 Orleans American. 



"The reputatii)n of the author is a guarantee that the work is a good one. 

 On examinalidU we find it to be so. It is an ad iiirable compend of the 

 Bubject'5 of which it treats: — we should think, indeed, that it would attract 

 the attention of teachers, both from its cheapncs-, and the admirable manner 

 in which it is arrmged." — Cincinnati Gazette. 



" 77/6 Second Book: — this number treats of all animals that in infancy 

 feed on the milk of thtir mothers; from the human being down to the mus- 

 quito-catching bit — 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 miik." — Neio York Era. 



"We do not k^ovv 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 encomiu'ns bestowed upon it; taken as a whole the work may be 

 ju.^ily regarded as invaluable to schools." — Neiv York Standard. 



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

 our seminaries, — we know of nothing equal to it. It is very flatteringly 

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

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



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

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

 His former volume has already been received iuto *ome of our public schools 

 and we hope both it and the present may find ihiir 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 

 public instructor should neglect to give it a place in his academy. — Phila^ 

 deljthia Spirit of the Times. g
