lation to the dumb animals than I could have acquired 

 in any other way. A physician thus trained to see, 

 hear, and feel the throb and the internal machinery of 

 life in such laboratories cannot help possessing greater 

 knowledge and approaching his patients with keener 

 sympathies than one who has not enjoyed such advan- 

 tages. Such training alone can ever make it possible 

 for a young physician to acquire the knowledge and 

 experience so necessary for treating his patients suc- 

 cessfully. His feelings of sympathy for all living 

 things and his sense of responsibility for human life 

 have been rendered keener rather than duller as the 

 anti-vivisectionists would have it; he is, so far as hu- 

 manity is concerned, the moral superior of any one 

 not so trained. Biology refines what is most human 

 in man. 



Summing up, and looking back upon an experience 

 of twenty-five years as a physician and surgeon in the 

 United States Navy, I state with truth and frankness 

 my opinion that the knowledge which I prize most 

 and which my patients have had the best reasons for 

 holding highest in me, is that which I have acquired 

 from practical contact with life and living things in the 

 various biological laboratories. 



I shall ever be grateful to those who gave me the 

 opportunity. 



Very truly yours,
