A BRIEF SUMMARY OF THE PROBLEM 163 



any time which may be regarded as belonging to a near 

 futm-e. And since we are not here concerned with the 

 milk supply of a far-off future, but with that of the 

 living present, our problem resolves itself into one of 

 getting the best result from cow's milk and of over-

 tute for the milk of the human mother. To that end 

 we need both science and 



" Good sense, which only is the gift of Heaven, 

 And though no science, fairly worth the seven. " 



Science lays an unerring finger upon the disadvan- 

 tages of cow's milk. It watches the infant human 

 stomach at work trying to digest what was intended 

 for an infant of a very different species, and a flood of 

 light is shed upon some of the most difficult aspects 

 of the problem of substitute feeding. By means 

 which in other ages would have been called miraculous, 

 science reveals the secret of each drop of milk; and 

 where the layman, like another Peter Bell, sees only , 

 a drop of milk and nothing more, the man of science 

 sees a little world teeming with life and wonders as

 we breathe myriad living forms which no human eye 

 unaided can see. He notes the manner in which many 

 of these infinitesimal creatures enter man's food, and 

 how some of them carry disease and death wherever 

 they go. He takes a single drop of milk which is fair 

 and pleasing to the eye, divides the drop, and spreads
