its parts upon his gelatin plates and then, by the aid 

 of his microscope, shows that the smallest division of 

 a drop is full of life, mysterious life in which good and 

 evil are at war as in all the great universe. 



A baby dies and the scientist finds in the little body 

 sores and lesions which he does not imderstand until 

 he has learned by repeated observation that in every 

 sore and lesion there are numerous little living micro- 

 organisms, exactly like some of those contained in the 

 drop of milk, and that there are very similar sores 

 and lesions in the body of the cow from which the milk 

 was drawn. Or a number of babies die as a result 

 of an epidemic of some gastro-intestinal disease for 

 which there seems to be no explanation, until the 

 scientist, examining the digestive tract in each little 

 body, finds in each a number of these micro-organisms, 

 bacteria of various kinds, which are similar in aU 

 respects to those found in the dirt of the stables where 

 the cows upon the milk of which the babies were fed 

 are kept, or to the bacteria that are present in the dirt 

 found in the babies' homes. Dr. Booker, of Balti- 

 more," found thirty-three different kinds of bacteria 

 in the intestines of little victims of that deadly foe 

 of babyhood which mothers call "summer com- 

 plaint" and the doctors call "cholera infantum." 

 This is only one of a great many illustrations tend- 

 ing to prove that the diarrhoeal diseases which kill 

 so many babies — half of those that die in the big
