LETTER OF TRANSMITTAL. 



U. S. DEPARTMENT or AGRICULTURE, 



BUREAU OF CHEMISTRY, 

 Washington, D. <?., February 6, 1909. 



SIR : I have the honor to submit for your inspection and approval 

 a report containing the results of inquiries made by the Division of 

 Drugs in order to obtain reliable information in regard to the harm- 

 ful effects of acetanilid, antipyrin, and phenacetin. The investiga- 

 tion was undertaken at this time because the attention of the Bureau 

 of Chemistry has been drawn to the subject in connection w r ith the 

 labeling in accordance with the food and drugs act, of drug products 

 containing one or more of these agents. I recommend that this re- 

 port be published as Bulletin 126 of the Bureau of Chemistry. 

 Respectfully, 



H. W. WILEY, 



Chief of Bureau. 

 Hon. JAMES WILSON, 



Secretary of Agriculture.
