VIS MEDICATRIX NATURE 633 



natural death altogether; the numberless arrangements for 

 keeping the earth clean and sweet; the hygienic value of 

 sunshine and fresh air. 



These matters lie outside our proper theme, but they 

 are well worthy of being recalled. Even when one is able 

 to give a reasonable account of how they have come to be, 

 they illustrate the balance and adaptiveness which is charac-

 it remains true of the child who goes forth every day that 

 " what he sees becomes part of him for a day, or for a year, 

 or for stretching cycles of years ". It seems a pity that 

 the modern child is often unfamiliar with the Scriptures;
