IN  THE  PREPARATION  OF  PHOSPHORIC  ACID 
by  the  process  recommended  at  the  Boston  meeting  of  the  Amer. 
Phar.  Assoc.,  Dr.  W.  H.  Pile  of  this  city,  we  regret  to  say,  has  been 
severely,  though  not  dangerously,  injured  by  the  sudden  explosion  of 
the  retort  containing  the  phosphorus,  nitric  acid  and  a  little  bromine. 
We,  therefore,  hasten  to  inform  our  readers  of  the  danger  connected 
with  this  process,  and  would  suggest  the  utmost  caution. 
Editor  Amer.  Jour.  Pharmacy.
