RECOMMENDATORY NOTICES. 



ORNITHOLOGY. This is No 3, and like its predecessors is excellent 

 These are the most valuable additions of the day to our stuck of School- 

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

 dented. Though the first vol. was published 'or the first time only a Ie\\* 

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

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

 than either of the other two. These books h ive been adopted by the 

 "Royal Council of Public In.-truotion" lor the use of Schools ihrougliout 

 France. They are recommended and have been adopted by some of the 

 most eminent teachers in the United States. Southern Lit Mes, 



The present book conveys a large amovnt of useful and pleasing 

 information on Ornithology. The structure, functions, and habits of Birds, 

 are classified and grouped in such a manner as to gratify the student of 

 Natural History, and at l\ e same time to aid the tyro in remembering the 

 oeculiarities of individual birds, and their various points of resemblances to 

 others of their family. Bulletin of Medical Science. 



The Third Book of Natural History is worthy of being placed alongside 

 the first and second. Ol thrse we have already spoken; and we may now, 

 we presume, congratulate Dr. Ruschenberger and the publishers, that 

 sufficient encouragement has been received t> induce them to Continue their 

 interesting and instructive series. American Medical Intelligencer. 



The series of books of which this forms a part has been highly and justly 

 commended bv the ablest judge?, HS furnishing rare facilities in the 

 acquisition of branches of knowledge, but too much neglected in our schools. 

 We have examined the volumes with much care, and we find them well 

 deserving all the praise bestowed on them. Cody's Lady's Book. 



DR. RUSCIIENBFRGER'S series of books on Natuial History are among the 

 most valuable and u-eful works for the use of schools that have ever been 

 published. The text is that of two d. stugir.shed French Naturalists, Milne 

 Edwards and Achille Comte translg'.ed und prepared for the use of 

 schools and colleges by Dr. Ruschenberger, who deserves great credit for 

 thus devoting his leisure to so useful an object. A knowledge of Natural 

 History is not only valuable, but deeply interesting, nnd no one's education 

 can, with such facilities as are now offered, be considered complete without 

 it. Simple and comprehensive as the elements of this science have been 

 made by the French professors and Dr. R., and adopted as they should 

 be, in schools and colleges, it would be inexcusable in any youth to be 

 ignorant of these elements, and having acquired them he will find it equally 

 easy and pleasant to enlarge his knowledge by consulting more extended 

 works, and devoting his attention to the study of the various branches of 

 this interesting science. The present book on Ornithology is upon the same 

 plan and possesses the same merit as those that have preceded it, and which 

 have been received with deserved commendation. It is brief and compre- 

 hensive, but sufficiently full to give the student a thorough knowledge of 

 the elements of Ornithology. It contains also a Glossary of the terms used 

 in this branch of Natural History, and a number of wood cuts illustrative 

 of the matter contained in the body of the work. Washington Nationa, 

 Intelligencer 



Precisely the work to place in the hands of young people. Madisonian. 



" We have much pleasure in commending this series of works the third 

 ef which now before us, is rn Ornithology, It will be found useful in the 

 chool-roorw, 01 the private study." U. S Gazette.
