ANTIDOTE AGAINST CORROSIVE StTBLIMATE. 



In the course of his experiments on gluten, Dr. Taddei found, 

 that wheaten flour and gluten reduced corrosive sublimate to 

 the state of calomel, and that considerable quantities of a mix- 

 ture of flour or gluten, with corrosive sublimate, might he taken 

 bv animals without any injurious effects. In this way, four- 

 teen grains of sublimate were given in less than twelve hours 

 to rabbits and poultry without inj'ny, whereas a single grain 

 would have been fatal, if taken alone. In order to render a grain 



of
