MEDICINE AND MORALS 



sentient living tissue with some sharp in- 

 strument for the purpose of originating 

 disease in the animal the examination or 

 results of which may aid, directly or 

 through the understanding of the disease, to 

 its cure. This is legitimate and should be 

 free to all medical practitioners and 

 students, under only the ordinary restric- 

 tions against cruelty to animals. In this 

 way antitoxin is obtained against diphthe- 

 ria, and also vaccine virus. 



2. Merely didactic. The cutting of 

 sentient living tissue by or before students 

 for the mere purpose of elucidating already 

 known points in the sciences. This should 

 be forbidden altogether. The risk of pain 

 and torture is too great. 



3. Scientific. The cutting of sentient liv- 

 ing tissue for the purpose of obtaining new 

 and important information in physiology. 

 This should be permitted to accredited 

 physicians and professors, but only under 

 rigid safeguards.
