The production of normal infants' milk is a field 

 of work that stretches over so many industries and 

 sciences that a thorough mastering of them can im-

 undertake the manufacture of " normal infants' food," 

 but a familiarity with the scientific principles of all 

 and every operation comprised in the manufacture 

 should most decidedly form a fundamental part of his

 farmer writing for farmers. 



I have to thank Dr. H. Weigmaun, of Kiel, for the 

 permission kindly granted to translate from his excel- 

 lent work the bacteriological part of this treatise, 

 which I herewith recommend to the indulgence of all 

 those who are, and also of those who should be, in- 

 terested in the amelioration of the conditions for pro- 

 ducing a healthy food for infants.
