IO4 ANIMAL EXPERIMENTATION 



chest. The lungs are moving. Sensitive recording levers 

 are tracing upon a revolving drum covered with smoked 

 paper a highly magnified record of the changes in the 

 heart-beat and the respiration. The investigator moves on 

 tip-toe, for fear of making the floor vibrate. He knows 

 that even the jar caused by the passing of a heavy cart in 

 the street may be recorded by his magnifying levers. He 

 is tense with the effort of controlling all the complex detail 

 of the fast-moving experiment. The blood supply to the 

 heart, the air for the lungs, the revolving record, the solu- 

 tion of the drug, and a dozen other matters-- all must be 

 watched at once. Eyes, ears, and hands must be con- 

 stantly occupied. In this crucial moment the door flies 

 open and in walks the agent. In a trice the experiment is 

 ruined, --the fruit of anxious hours is gone. The animal 

 is sacrificed for nothing. The practitioner must wait till 

 another time for knowledge of this remedy. The zealous 

 agent bustles about the room. Such delicacy of feeling 

 as may be left in a man who will accept such duties impels 

 him to justify himself, if possible. 



" What anesthetic are you using?" he asks the indignant 

 scientist. 



" None. The animal is dead." 



"What's this? The animal dead? Preposterous! Why, 

 can't I trust my own eyes? Here is the heart beating 

 regularly, and the lungs are moving, too." 



Imagine the report. How will the man speak of this 

 profound and humane investigation? How will he know 

 that the heart and lungs have been kept alive by the skill 

 of the scientist, while the rest of the body has been allowed 

 to die? 



The proposed legislation will, beyond all question, put 

 an end to many investigations in medicine and biology, 

 and will hamper the researches which it docs not prevent.
