PREFACE. 



The necessity of pi-oviding nurses in children's hos- 

 pitals with a good article of food in a pure, unadulter- 

 ated and convenient form for their patients, has led The 

 Emperor and Empress Frederick Hospital for Children 

 to pay special attention to the fulfillment of this need. 

 Definite arrangements were made with an owner of a 

 dairy in close proximity for controlling the selection of 

 cattle, method of feeding, care and milking, thereby se- 

 curing a good clean product. 



The prompt fulfillment of these terms was under the 

 control of Dr. Sommerfield, and it is through his efforts 

 in ascertaining the most expedient and efKcient methods 

 of control that this little book has been published. 



It will certainly be of interest to those who are en- 

 trusted with the care of children in similar institutions 

 to learn of this publication, and we hope, also, that it will 

 be of equal service to many others.
