of food will best support the body and yield it heat. There 

 is a science of Food or Dietetics as surely as there is a science 

 of Astronomy or Geology, and it is of much more consequence 

 to "the man in the street". 



Similarly Science underlies the practice of proper venti- 

 lation; a knowledge that the constant removal of bedroom 

 air without a draught is necessary to health would save 

 thousands of lives annually from being cast upon the void 

 of tubercular infection. There is a science of Ventilation, 

 first expounded and practised by an English church clergy- 

 man, the Rev. Stephen Hales, D. D., F. R. S., in the eighteenth 

 century, but by no means understood today even by some 

 most eminent architects. And does not science or exact 

 knowledge underlie the choosing of clothes' stuffs and even 

 the wearing of clothes? If, as Carlyle insisted, there is a 

 philosophy of clothes, there is surely also a science of clothes. 

 A knowledge of animal calorimetry will inform us as to the 

 composition, weight, color, texture and much else of the 

 clothes to be worn under varying conditions. 



And so, too, science has something to say about such 

 commonplace things as the duration of sleep proper to 

 different ages of the child and of the j^outh; how the lack 

 of it leads to inefficiency at school, how work before breakfast 

 for school children is a physiological immorality. Science 

 has something to say about the arrangment of hours of 

 work and play in the school time-table, how fatigue of body 

 and of mind can be recognized, prevented or cured, how 

 the congenitally deficient child may be distinguished from 

 the backward or merely lazy one. Science explains the 

 significance of night-terrors, of growing pains, of headaches, 

 of uncontrollable sleepiness in children; it has views on the 

 games suitable for boys and girls at different ages; it super- 

 vises the gymnasium, the swimming-bath and the playing- 

 field. The man of applied science, the physician, recognizes 

 dilated heart, cardiac palpitation, and many of the significant
