In 1908 the Hygienic Laboratory of the United States Public 

 Health Service published a large volume entitled "Milk and its 

 Relation to the Public Health," embodying monographs on the 

 various phases by different collaborators. This was revised and 

 enlarged and republished as Bulletin No. 56 of the Laboratory, 1909. 



Bulletins on various subjects relating to milk and to dairy hus- 

 bandry and industry are constantly being published by the United 

 States Public Health Service, by the United States Department of 

 Agriculture, and by state departments of agriculture and experiment 

 stations. Papers and notes appearing in such journals as ar
