tanning.  There  has  always  been  a  difficulty  connected  with  such 
operations,  due  to  the  changes  which  gelatin  undergoes  so  very 
readily  when  in  aqueous  solution,  thus  rendering  the  making  of 
a  new  solution  and  its  titration  necessary.  The  complete  solu- 
bility of  gelatin,  in  even  concentrated  glycerin  and  the  well 
known  antiseptic  quality  of  the  latter,  render  it  very  probable 
that  a  solution  of  the  former,  in  even  dilute  glycerin,  may  be 
kept  unaltered  for  some  time,  in  which  case  much  time  would  be 
Baved  in  such  establishments  where  the  assaying  of  tanning  ma- 
terial has  to  be  frequently  performed.  I  hope  to  be  able  to 
extend  my  experiments  in  this  direction  and  to  report  thereon 
at  some  future  time. 
CAMPHOR  LINIMENT  AN  ANTIDOTE  TO  THE  IRRITATION 
OF  COWHAGE.

Edtior  Am.  Journal  Pharmacy  : 
Sir — In  cleaning  our  store  yesterday,  one  of  our  men  came 
across,  a  can  not  labelled.  Not  knowing  what  it  was,  he  took 
some  out  with  his  hand  to  examine  it ;  the  same  time  he  called 
one  of  the  boys,  and  asked  him  if  he  knew  what  it  was  ;  not  know- 
ing, he  also  took  some  in  his  hand.  A  short  time  afterwards, 
they  both  came  to  me,  bringing  the  can  with  them,  and  told  me 
all  about  how  they  got  it  on  them.  They  said  it  itched  terribly, 
and  wanted  me  to  apply  something.  The  can  contained  cowhage. 
They  tried  to  wash  it  off  with  soap  and  water  before  they  came 
to  me.  I  applied  some  olive  oil,  and  several  other  oils,  which 
relieved  them  not  the  least.  A  bottle  of  Camphor  Linwient 
being  near  at  hand,  I  tried  some  of  that,  which  relieved  the  itch- 
ing sensation  at  once.  Seeing  that  it  relieved  the  itching  so 
quickly,  I  put  some  cowhage  on  my  hand ;  after  the  itching  com- 
menced, I  applied  some  of  the  Camphor  Liniment,  which  relieved 
me  in  an  instant.
