 SIR: I beg leave to submit for your approval a detailed report on 

 the experiments undertaken in this Bureau to ascertain the effects of 

 boric acid and borax on digestion and health. 



In connection with the various phases of the work credit is given to 

 those who performed it, but special mention should be made of the 

 cooperation of the Bureau of Statistics, where the analytical data were 

 tabulated. This assistance has been invaluable and has expedited the 

 publication of the report. Acknowledgment is also due to the Public 

 Health and Marine-Hospital Service for the medical supervision given 

 during the experiment. 



1 recommend the publication of this manuscript as Part I of Bul- 

 letin No. 84 of the Bureau of Chemistry. 

 Respectfully,

 Hon. JAMES WILSON,
