96 THE POPULAR SCIENCE MONTHLY. 



with the disease subsequent to inoculation with the most potent 

 virus. 



Surely results such as those recorded in this book are calculated, 

 not only to arouse public interest, but public hope and wonder. Never 

 before, during the long period of its history, did a day like the present 

 dawn upon the science and art of medicine. Indeed, previous to the 

 discoveries of recent times, medicine was not a science, but a collection 

 of empirical rules dependent for their interpretation and application 

 upon the sagacity of the physician. How does England stand in rela- 

 tion to the great work now going on around her ? She is, and must 

 be, behindhand. Scientific chauvinism is not beautiful in my eyes. 

 Still, one can hardly see, without deprecation and protest, the English 

 investigator handicapped in so great a race by short-sighted and mis- 

 chievous legislation. 



A great scientific, theory has never been accepted without opposi- 

 tion. The theory of gravitation, the theory of undulation, the theory 

 of evolution, the dynamical theory of heat all had to push their way 

 through conflict to victory. And so it has been with the germ theory 

 of communicable diseases. Some outlying members of the medical 

 profession dispute it still. I am told they even dispute the communi- 

 cability of cholera. Such must always be the course of things, as long 

 as men are endowed with different degrees of insight. Where the 

 mind of genius discerns the distant truth, which it pursues, the mind 

 not so gifted often discerns nothing but the extravagance, which it 

 avoids. Names, not yet forgotten, could be given to illustrate these 

 two classes of minds. As representative of the first class, I would 

 name a man whom I have often named before, who, basing himself in 

 great part on the researches of Pasteur, fought, in England, the battle 

 of the germ theory with persistent valor, but whose labors broke him 

 down before he saw the triumph which he foresaw completed. Many 

 of my medical friends will understand that I allude here to the late 

 Dr. William Budd, of Bristol. 



The task expected of me is now accomplished, and the reader is 

 here presented with a record in which the verities of science are en- 

 dowed with the interest of romance.

TEAINING IN ETHICAL SCIENCE. 



By H. II. CUETIS. 



THE importance of education in the duties of life is recognized in 

 a greater or less degree by all. People differ widely as to abso- 

 lute standards of right and wrong, and as to the foundation or source 

 of such standards, but all concede by daily acts, as well as by avowed 

 opinions, the necessity of some kind of moral training. Every parent
