till  solution  is  effected,  which  is  intimately  mixed  with  one-half  of  its 
weight  of  plaster  of  Paris.  The  mixture  hardens  within  one  hour, 
and  is  impermeable  for  coal  oil. — Puscher,  Pharm.  Zeit.  BussL,  xxiii^

Creasote. — A  more  manageable  form  for  toothache  than  the  pure 
article  is  creasotated  collodium  (equal  volumes  creasote  and  collodium), 
which  forms  a  kind  of  varnish  over  the  carious  tooth. — Ibid.,  p.  6.' 
Pain  Paint. — Against  migraine,  toothache,  etc.  5  grams  oil  of  pep- 
permint, 10  grams  chloroform,  6  grams  acetic  ether,  10  drops  essential

Itch  Remedy. — Wash  the  whole  body,  on  going  to  bed,  with  a  solu- 
tion of  hyposulphite  of  sodium  (1:5),  and  the  next  morning  with

Purity  of  Copaiva  Balsam  demonstrated  microscopically. — Place  a 
drop  of  the  balsam  on  a  slide,  and  dust  in  a  few  grains  of  canna 
starch.  If  pure,  the  starch  granules  will  be  invisible ;  if  the  balsam, 
however,  be  adulterated,  its  altered  refractive  power  will  cause  the 
starch  to  become  visible. — Ibid.,  x,  p.  598.
