was  uniformly  continued  for  thirty  minutes.  In  a  few  doubtful  cases 
the  hydrogen  was  permitted  to  be  generated  for  one  hour.  It  was 
considered  that  a  longer  time  than  this  was  absolutely  unnecessary, 
inasmuch  as  chemists  realize  that  if  large  enough  quantities  are 
taken,  and  the  reaction  allowed  to  continue  sufficiently  long,  a  trace 
ot  arsenic  can  be  obtained  from  almost  all  substances. — Read  at  the

PHARMACEUTICAL  AND  CHEMICAL  NOTES. 
By  Clement  B.  Lowe. 
I  have  some  matters  of  interest  to  bring  before  this  meeting  this 
afternoon  which  I  hope  will  be  of  some  practical  value. 
The  first  is  a  blank  form  which  I  have  had  printed  for  keeping  a 
record  of  prescription  renewals.  It  largely  explains  itself.  At  the 
close  of  the  day's  business  the  column  entitled,  "  Renewal  No.," 
which  has  been  left  blank,  is  filled  in  by  the  numbering  machine, 
At  the  end  of  the  year  the  prescription  number  represents  the  exact 
number  of  prescriptions  compounded  during  the  year.  This  plan  of 
keeping  account  of  renewals  helps  us  greatly  in  keeping  our  numer- 
ous charge  accounts  straight,  and  also  in  renewing  prescriptions.

Whenever  I  attend  a  pharmaceutical  meeting  I  try  to  bring  away 
from  it  something  of  value,  be  it  small  or  great.  Acting  upon  the 
suggestion  of  Mr.  Ruhl,  of  Manheim,  as  presented  at  the  Pennsylva- 
nia Pharmaceutical  Meeting-,  I  show  you  a  three-cornered  file,  and 
the  deft  manner  in  which,  by  means  of  it,  a  cork  can  be  extracted 
from  a  bottle.  Owing  to  its  shape,  it  has  the  disadvantage  of  being 
hard  to  pick  up.  Another  suggestion  which  I  show  you  is  the  cap 
of  a  castor-oil  can,  whjch  has  had  a  round  hole  cut  in  it  and  a  tin 
tube  soldered  to  it,  so  that  the  oil  can  be  poured  out  without  spill- 
ing a  drop.    This  cap  will  fit  all  cans  of  the  same  make.
