vi PREFACE 



earlier made valuable reports upon certain portions of the subject 

 to the Local Government Board, to assist them in collecting the 

 available scientific evidence upon the hygienic relations of milk 

 from all the best sources of information, however widely scattered. 

 By the courtesy of the Local Government Board, the services 

 of Dr. Lane-Claypon were made available for this work, and in 

 due time its results were before the Committee. 



It seemed to the Committee that this collection and critical 

 summary of the published work upon the subject was likely to 

 be valuable to many of those engaged in research work connected 

 with it, and no less valuable to those concerned with the administra- 

 tive questions which centre round the problems of milk and its 

 proper treatment as a food. They have accordingly arranged for 

 its publication, and in doing this they have endeavoured to secure 

 that it shall be made available at the lowest price compatible 

 with efficiency of production. 



It has further been the hope of the Committee that the treat- 

 ment of her material by Dr. Lane-Claypon has been such as to 

 allow those ignorant of scientific technology to appreciate the 

 chief positions which knowledge has gained in this matter, and 

 that for this reason the book may have added value in bringing 

 the illumination given by scientific work to those who are responsible 

 for the formation of public opinion and for the determination of 

 administrative action.
