LETTER OF TRANSMITTAL 



U. S. DEPARTMENT OF AGRICULTURE, 



BUREAU OF CHEMISTRY, 

 Washington, D. C., August 12, 1905. 



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

 a manuscript containing the results of an investigation conducted in 

 the Insecticide and Agricultural Water Laboratory (now the Miscel- 

 laneous Laboratory) of this Bureau on the mineral waters offered for 

 sale to the people of the United States. The object of this investiga- 

 tion was to determine the adulteration of these beverages by showing 

 in what degree they conform to the claims which are made respecting 

 their composition. The information afforded by these data is of great 

 value to the public in general and to physicians in particular. The 

 data contained in this report should not under any circumstances 

 be used for any advertising or commercial purposes. I recommend 

 that this report be published as Bulletin No. 91 of the Bureau 

 of Chemistry. 



Respectfully, 



W. D. BIGELOW, Acting Chief. 

 Hon. JAMES WILSON, 



Secretary of Agriculture.
