LETTER OF TRANSMITTAL 



U. S. Department of Agriculture, 



Bureau of Chemistry, 

 Washington, B.C., October 19, 1907. 

 Sir: I have the honor to transmit herewith the results of a chem- 

 ical study of various preparations made from meat, and some sub- 

 stances used to adulterate such products. In addition, comments 

 on the nutritive value of meat extracts and similar products have 

 been compiled from the literature of the subject. The wide use of 

 preparations of this nature by invalids and others seeking a con- 

 centrated nutritious food rather than a stimulant, and the fact that 

 but little is generally known of the actual composition of these prod- 

 ucts, make it advisable to publish the information obtained in the 

 course of these studies, which were primarily conducted for the estab- 

 lishment of standards. 



I recommend that this manuscript be published as Bulletin 114 of 

 the Bureau of Chemistry. 



Respectfully, H. W. Wiley, 



Chief of Bureau. 

 Hon. James Wilson, 



Secretary of Agriculture.
