662 THE POPULAR SCIENCE MONTHLY. 



which I have tried to stir : a larger and more practical recognition of 

 the. value and happiness of good national health ; a wider study and 

 practice of all the methods of promoting it ; or, at least, a more ready 

 and liberal help to those who are striving to promote it. In one sen- 

 tence, we want the complete fulfillment of the design of this Exhibition, 

 Avith all the means toward health and knowledge that are shown in it, 

 and with its hand-books, lectures, conferences, and the verdicts of 

 its juries. 



We want more ambition for health. I should like to see a personal 

 ambition for renown in health as keen as is that for bravery, or for 

 beauty, or for success in our athletic games and field-sports. I wish 

 there were such an ambition for the most perfect national health as 

 there is for national renown for war, or in art or commerce. And let 

 me end soon by briefly saying what I think such health should be. 



I spoke of the pattern healthy man as one who can do his work 

 vigorously wherever and whatever it may be. It is this union of 

 strength with a comparative indifference to the external conditions of 

 life, and a ready self-adjustment to their changes, which is a distinct- 

 ive characteristic of the best health. He should not be deemed thor- 

 oughly healthy who is made better or worse, more or less fit for work, 

 by every change of weather or of food ; nor he who, in order that he 

 may do his work, is bound to exact rules of living. It is good to 

 observe rules, and to some they are absolutely necessary, but it is 

 better to need none but those of moderation, and, observing these, to 

 be able and willing to live and work hard in the widest variations of 

 food, air, clothing, and all the other sustenances of life. 



And this, which is a sign of the best personal health, is essential to 

 the best national health. For in a great nation, distributed among its 

 people, there should be powers suited to the greatest possible variety 

 of work. No form or depth of knowledge should be beyond the 

 attainment of some among them ; no art should be beyond its reach ; 

 it should be excellent in every form of work. And, that its various 

 powers may have free exercise and influence in the world, it must 

 have, besides, distributed among its people, abilities to live healthily 

 wherever work must be or can be done. 



Herein is the essential bond between health and education ; herein 

 is one of the motives for the combination of the two within the pur- 

 pose of this Exhibition ; I do not know whether health or knowledge 

 contributes most to the prosperity of a nation ; but no nation can 

 prosper which does not equally promote both ; they should be deemed 

 twin forces, for either of them without the other has only half the 

 power for good that it should have. 



It is said, whether as fact or fable, that the pursuit of science and 

 of all the higher learning followed on the first exercise of the human- 

 ity which spared the lives of sick and weakly children ; for that these 

 children being allowed to live, though unfit for war and self-main-
