OPINION OF THE RIGHT REV. CHAS. P. McILVAINE, p. D. 



Bishop of the Protestant Episcopal Church, Diocese of Ohio ; President of 

 Kenyan College, fyc. 



Kenyon College, Gambier, Ohio, Feb. 1842. 

 MESSRS. TURNER & FISHER: 



Gentlemen, On reaching home, after a long absence, I had the pleasure 

 of reciving the copy of the work prepared by Dr. Ruschenberger on Physi- 

 ology and Animal Mechanism, for the use of schools. If my opinion of its 

 merits can be of any service to its circulation, I am free to say that not only 

 are the subjects of the work such as ought to enter into the course of study 

 of the higher classes of our schools, but this work seems to me to be well 

 adapted to the want of .schools in reference to its subjects. At any rate, I 

 know not a better for its professed purposes. 



Yours, very truly, and respectfully, 



CHAS. P. McILVAINE.

 nicating the elements of this interesting branch of science in so cheap and 

 clwar a form.

OPINION OF THE HON. DANIEL STURGEON, 



United Stales Senator from Pennsylvania. 



Senate Chamber, Washington City, Jan. 29th, 1842. 

 MESSRS. TURNER & FISHER. 



Gentlemen. I have examined with some care the two small volumes you 

 <vere so kind as to send me. 



I think Dr. Ruschenberger has succeeded in condensing into as small a 

 space as possible, much valuable information on the subject of which he 

 treats, and think the work admirably calculated to impart general knowledge 

 on this interesting subject. 



I will be pleased to see it adopted in our high schools and colleges as a 

 textbook. 



With sentiments of respect and esteem, yours, 



DAN'L STURGEON. 



OPINION OF THE HON. SAMUEL L. SOUTHARD, 



United States Senator Jrom New Jersey. 



Washington, Feb. 15th. 1842. 

 MESSRS. TURNER & FISHER. 



Dear Sirs, I am gratified by your kindness, in sending me the two 

 volumes referred to, in your letter of the 31st of January. I entirely concur 

 in the objects you desire to accomplish. Few things can be more important 

 to our common country. My incessant and inexorable duties, have, thus far, 

 prevented me from making that examination of the volumes which I desire. 

 I am respectfully, &c. &c. 



SAMUEL L. SOUTHARD
