PREFATORY NOTE. 



DECEMBER 12, 1889. 



SIR : I have the honor to submit herewith the report of Mr. A. J. 

 Wedderburn, special agent of the Department, on the extent and charac- 

 ter of food adulterations. 



The object of the present bulletin is wholly distinct from that pursued 

 in bulletin No. 13. The investigations, of which the present bulletin 

 is the result, were undertaken for the purpose of collating in popular 

 form well-authenticated facts respecting food adulterations, in order that 

 the people and Congress might have, at least, a general view of the evil 

 which it is hoped Mr. Wedderburn's work may help to remove. 

 Eespectfully, 



H. W. WILEY, 



Chemist. 

 Hon. J. M. KUSK, 



Secretary.
