RECOMMENDATORY NOTICES. 



" Ruschenberger's Series of Books on Natural History, are among the 

 most valuable and useful works, for the use of Schools that have ever been 

 published. A knowledge of Natural History, is not only valuable, but 

 deeply interesting; and no one's education can, with such facilities as these 

 works afford, be considered complete without it." National Intelligencer. 



" These are the most valuable additions of the day to our stock of School 

 Books. The avidity with which they have been seized upon is unprece- 

 dented. Though the first vol. was published for the first time only a few 

 months ago, it has already gone through its fifth edition; the second is fol- 

 lowing close upon its heels; and the third promises even to be more popular 

 than either of the othe*r two. These books have been adopted by the * Royal 

 Council of Public Instruction,' for the use of Schools throughout France. 

 They are recommdfned and have been adopted by some of the most emi 

 nent teachers in the United States." Southern Literary Messenger.

"RuscHENBERGER's ORNITHOLOGY: Grigg & Elliot. This is an excel- 

 lent book, by one who shows himself perfectly qualified for the task he haa 

 undertaken, which is the publishing of a series of works on the different 

 branches of education, for the use of schools and colleges. The present 

 issue is a general and synoptical view of Ornithology, one of the most 

 interesting subjects in Natural History, and will be found of great service, 

 both to teacher and student." 



M This is a compendious, and, as it seems to us. a judiciously compiled 

 treatise on Ornithology, and one well calculated for the use of Schools ; for 

 which object it is intended." N, Y. Courier and Enquirer. 



** In the work before us, the plan is happily carried out. In its small 

 compass it embraces an immense amount of useful and interesting infor. 

 mation." Buffalo Adv. and Journal. 



41 Ornithology. This is evidently, like its predecessors, an excellent work 

 of instruction ; and hai been, in all respects well got up by the publishers." 1 

 Pennsylvanian. 



"A valuable little work, and is divided up and classified admirably. The 

 glossary, giving the derivation of the names of birds, is of itself worth the 

 price of the volume." New York Aurora. 



** An exceedingly interesting, and very instructive book, and one which 

 possesses special attraction for young ladies." Baltimore Sun. 



"RUSCHENBERGER'S SERIES : Second Book. A highly useful and instructive 

 school book. Third Book, This we consider as decidedly an acquisition 

 to our list of school books, the subject is treated of in such a plain style aa 

 to be adapted to the simplest capacity. Altogether we think the above 

 eries as worthy to take a high and permanent place among our school 

 books." Buffalo Democrat. 



"We wish we could induce our teachers generally to examine this, a* 

 well as the earlier works of Dr. Ruschenberger ; they are admirably 

 arranged, and just the very books needed for schools. The work before 

 us on the Natural History of Birds is an admirable one, and no teachei 

 hould neglect to introduce the series. 'Cincinnati Gazette. 



* It is an excellent text-book of an interesting science, comprising much 

 knowledge in a brief space, presented in a clear style and with lucid 

 arrangement. Dr. Ruschenberger, who has already achieved a high charac 

 ter m the literary world, is acquiring additional claims by his exertions i 

 the field of Natural Science.- Spectator, Washington City.
