LETTER OF TRANSMITTAL 



UNITED STATES DEPARTMENT OF AGRICULTURE, 



BUREAU OF CHEMISTRY, 

 Wasliington, D. C., March 11, 1912. 



SIR: I have the honor to transmit for your approval the results of a 

 study made by the bacteriological chemist of this bureau and his assist- 

 ant of fresh eggs of known quality in the shell, and of frozen and desic- 

 cated eggs prepared from different grades of materials and under com- 

 mercial and laboratory conditions, in Washington, D. C. It is thought 

 that these data will be of special interest and profit to those manufac- 

 turing these products, in their endeavors to produce a more acceptable 

 foodstuff, as well as to the bakers, confectioners, etc., by whom they are 

 largely purchased. The eggs examined in this work were purchased 

 either direct from tne producers or in the open market and were 

 intended for direct consumption. The data obtained are therefore of 

 additional interest as compared with those secured at the factories 

 where eggs are prepared for preservation, which problem is now being 

 studied in an independent research conducted by this Bureau in col- 

 laboration with the Bureau of Animal Industry. 



I recommend that the manuscript be published as Bulletin 158 of 

 the Bureau of Chemistry. 



Respectfully, H. W. WILEY, 



Chief of Bureau. 

 Hon. JAMES WILSON, 



Secretary of Agriculture.
