BORIC ACID UPON NUTRITION. 41 



Borax and boric acid, when given in quantities equal to 

 1.5-2.0 per cent of the daily food are liable to produce nausea 

 and vomiting. 



Owing to the rapid elimination of both borax and boric acid, 

 no marked cumulative action can result from their daily in- 

 gestion in moderate quantities. 



At no time in these experiments was there any indication of 

 abnormality in the urine; albumin and sugar were never 

 present.
