These  were  set  aside.  The  crumb  bread  was  used  for  the  next 
excipient,  and  the  pills  sent  out  in  apparent  good  order.  Having 
heard  no  complaint,  it  is  presumed  that  the  preparation  gave 
satisfaction. 
In  speaking  of  the  phenomenon  to  the  prescriber,  no  explana- 
tion could  be  given.  The  formula  gave  the  Pharmaceutist  the 
largest  liberty.  A  few  remarks  in  your  journal,  giving  the 
apothecary  a  source,  or  authority,  I  know  would  give  general 
satisfaction.  Very  respectfully  yours, 
Baltimore,  July  1st,  1858.  Pharmacy. 
[Note. — We  have  on  two  or  ihree  occasions  noticed  a  reaction  in  pills 
into  which  oxide  of  silver  entered  as  an  ingredient.  After  receiving  the 
above  note,  it  was  observed  that  a  pill  composed  of  oxide  of  silver,  sugar, 
honey,  and  a  little  water  to  give  consistence,  had  undergone  a  change  by 
swelling  up  and  cracking  in  fifteen  minutes  after  it  was  prepared,  but  the 
change  was  not  witnessed  whilst  in  progress.  Afterwards  pills  were  made, 
composed,  1st,  of  oxide  of  silver  and  extract  of  gentian ;  2nd,  of  oxide  of 
silver,  liquorice  root  and  mucilage;  3rd,  of  oxide  of  silver,  powdered  sugar 
and  mucilage  •  but  in  neither  case  was  any  reaction  observed.  Our  impres* 
sion  is  that  the  reaction,  when  it  occurs,  is  between  the  grape  sugar  and 
oxide  of  silver,  and  that  it  requires  certain  favoring  circumstances,  which 
the  short  time  incident  to  the  passage  of  this  paper  through  the  press  does 
not  enable  us  to  detect. —Editor  Amer.  Jour.  Pharm.]

Liniment  of  Iodide  of  Potassium, 
In  the  fourteenth  volume  of  the  American  Journal  of  Phar- 
macy, the  late  Mr.  Duhamel  published  a  formula,  translated 
from  the  French  Journal  of  Pharmacy  and  Chemistry,  upon 
which  this  paper  is  based.  It  seemed  desirable  to  simplify  the 
formula  and  make  it  of  such  easy  execution  as  to  induce  its 
more  general  employment.
