Progress  in  Pharmacy.

As  a  mixer  for  horse  and  cattle  powder,  this  home-made  arrange- 
ment has  been  the  source  of  a  great  deal  of  satisfaction  to  the 
writer.  As  much  as  128  pounds  of  powder  has  been  mixed  at  one 
time  with  perfect  ease. 
A  Simple  Percolator  Support. — At  one  time  a  support  for  a  per- 
colator had  to  be  devised  tor  showing  a  pharmaceutical  operation 
in  the  show  window.  The  regular  retort  stand  not  being  high 
enough,  an  iron  rod  r5g-  inch  thick  (same  thickness  as  retort 
stand  rod),  and  about  22  inches  long,  shaped  by  a  blacksmith 
into  a  flat  U,  2  inches  high  and  about  16  inches  wide,  with  two 
holes  at  each  end  for  fastening  with  screws  against  the  wall,  was  the 
happy  solution.  After  the  window  display  was  over,  this  rod,  fas- 
tened against  the  wall,  back  of  the  working  counter,  has  done  excel- 
lent service  when  the  retort  stand  would  not  support  the  weight  ot 
a  heavy  percolator,  or  if  the  retort  stand  was  not  high  enough. 
The  excellent  feature  of  this  simple  support  is  its  rigidity.  No 
matter  how  large  a  percolator  is  fastened  to  it  (with  the  regular 
retort  rings)  it  is  always  firm. 
A  support  like  this  could  be  made  longer,  and  thus  offer  a  wider 
range  of  usefulness,  but  the  writer  would  much  prefer  to  have  two 
or  three  of  them,  and  have  them  fastened  at  different  heights  to 
the  wall,  for  greater  rigidity  is  thus  secured.  No  investment  of  a 
dime  has  ever  brought  as  great  returns  as  the  one  spent  for  this 
percolator  support.

Foreign  pharmaceutical  journals  have  been  giving  considerable 
attention  to  historical  matters  relating  to  pharmacy,  among  others 
the  PharmaceutiscJie  Post  has  published,  serially,  a  contribution  to 
the  "  History  of  Pharmacy  in  Germany  and  Austria,"  while  the 
Zeitschrift  des  Allgemeinen  Oesterreichisclien  Apotheker-Vereines  has 
been  publishing  installments  of  a  lengthy  u  History  of  Glycerin  as  a
