LETTER OF SUBMITTAL. 



U. S. DEPARTMENT OF AGRICULTURE, 



DIVISION OF CHEMISTRY, 

 Washington, D. (7., July 1, 1894. 



SIR : In compliance with my commission as special agent to examine 

 into the extent and character of food and drug adulterations, I have 

 the honor to submit the following report. Increased interest in this 

 subject, as shown by the great increasein correspondence, has compelled 

 me to go over the old ground to a considerable extent, but I believe 

 that new and interesting matter will be found herein. The character 

 of my commission did not authorize investigation of the scientific phases 

 of the subject which are so ably covered in the various parts of Bulletin 

 No. 13, issued under your direction. 

 Very respectfully, 



ALEX. J. WEDDERBURN, 



Special Agent. 

 Dr. H. W. WILEY, 



Chemist of the U. S. Department of Agriculture.
