rating  the  camphor;  a  portion  of  the  filtrate  was  neutralized  with  mu- 
riatic acid  and  tested  by  cupric  and  ferrous  sulphates  ;  it  did  not  yield  a 
precipitate.  I  then  estimated,  with  nitrate  of  silver,  the  quantity  of 
iodine,  and  found  one-tenth  grain  as  iodide  of  ammonium. 
From  the  results  of  a  number  of  experiments,  the  following  would 
give  a  very  similar  preparation,  containing  sufficient  "  iodide  of  ammo- 
nia "  to  give  it  a  name. 
Take  of     Iodide  of  Ammonium,  grs.  ii 
Camphor, 
Oil  of  Lavender,  ad^i 
Water  of  Ammonia,  ^iv 
Alcohol  sufficient  to  make  Oi 
Mix. 
If  a  liniment  of  iodide  of  ammonium  should  prove  desirable,  I  would 
suggest  the  following,  as  containing  iodine  in  a  form  of  combination — 
iodide  and  iodate,  most  favorable  for  absorption  and  the  elimination  of 
free  iodine. 
Take  of     Water  of  Ammonia,  (10  per  ct.)  f^ii 
Glycerin,  or 
as  I  prefer,  Soap  Liniment,  f^ii 
Tincture  of  Iodine,  f^viii 
Alcohol,  f^iv  or  q.  s. 
Mix  the  soap  liniment  (or  glycerin)  with  the  tincture  of  iodine  and 
add  the  alcohol  and  ammonia  ;  shake  and  add  alcahol  to  make  one  pint. 
When  first  mixed  it  is  of  a  ruby  red  color,  but  in  two  or  three  days 
becomes  colorless,  affording  a  cleanly  preparation,  which  may  be 
appropriately  called  a  liniment  of  "  iodide  of  ammonia, "  but  the  cor- 
rect name  of  which  would  be  Linimentum  ammonii  iodidi  et  iodatis.

CREASOTE  AND  CARBOLIC  ACID. 
By  Adolph  Graetzel.1 
In  England,  Morson's  creasote  is  preferred  to  beechwood-tar  creasote,, 
on  account  of  its  pleasant  oder.  Comparative  experiments  were  made 
with  it,  and  with  the  following  substances  :  crystallized  carbolic  acid  ? 
commercial  beechwood-tar  creasote,  highly  purified  and  distilling  com-
