100 ANIMAL EXPERIMENTATION

 discovery explains how life may sometimes be prolonged 

 for years in spite of the excessive narrowing, or even 

 obliteration, of many of the nutrient arteries of the heart. 

 It is in this systematic way, step by step, that Science 

 proceeds into the unknown.

The men who make discoveries lead toilsome lives. Iron 

 industry, tenacity of purpose, and profound sagacity led 

 Harvey to the discovery of the circulation of the blood. 

 We look with amazement and with reverence upon the 

 labors of Pasteur. Few may achieve such greatness, but 

 all who set forth to find new truths are inspired by the

 with inhumanity is as illogical as it is unjust. To demand 

 that his researches shall be placed under the supervision 

 of the humane societies is unwise. What society approaches 

 the practical humanity of the men engaged in medical 

 research? Biological research is already in the hands 

 of the governing boards of incorporated institutions of 

 learning. These boards are composed of the most dis- 

 tinguished citizens. Yet the little group of agitators are 

 not satisfied. They wish the control of research to be 

 placed in their own hands. 



I say " the little group of agitators " advisedly. The 

 persons who are responsible for these several attacks upon 

 research may be counted upon the fingers. Many of them 

 have declared publicly that animal experimentation is use- 

 less and morally wrong. Against the " vivisectors," as 

 they call them, they have exhausted epithet and invective. 

 Taught by previous failures that restriction equivalent to 

 abolition of animal experimentation cannot be obtained at
