REPORT 



On Dr. Ruschenberger's Elements of Ornitholog-y. 



I have received the " Elements of Ornithology," prepared for the 

 use of schools and colleges, by W. S. W. Ruschenbergcr, M. D., 

 and have read the work in compliance with the request of the 

 American Institute, that I should examine and report upon it. I 

 have great pleasure in highly recommending it. I consider the pre- 

 sent the very best introduction to that science that I have ever seen, 

 and I might add as full praise to the other works of the series of 

 " Ruschenberger's books of Natural History," as far as I am acquain- 

 ted with the subjects they relate to. 



Dr. Ruschenberger has, in giving this series to the public, rendered 

 a benefit to all seekers after science, as that old and young may pro- 

 fit by the well arranged and valuable information these volumes 

 contain.
