CREAM  OF  CAMPHOR. 
BY  OTTO  KRAUS,  PH.  G. 
[From  an  Inaugural  Essay). 
Cream  of  camphor  prepared  according  to  the  following  formula,  has 
been  used  successfully  in  inflammatory  affections  of  the  throat,  also 
catarrhal  and  other  pectoral  complaints  of  children,  it  having  the  ad- 
vantage over  the  linimentum  ammoniae,  U.  S.  P.,  on  account  of  being 
free  from  all  oily  matter. 
To  make  cream  of  Camphor,  take  of 
White  Castile  soap  (  in  shavings),        ......  Jiss 
Camphor,        ...........  511 
Carbonate  of  ammonium,            .     ■  .        .        .       .       .*       .  511 
Water,            ...........  Oiv 
Tincture  of  opium,  ,        .        .       .        .        .       .        .  f 
Oil  of  origanum,  .        .        .       .        .       .       .        .       .  f^i 
Alcohol  and  oil  of  turpentine,  of  each  a  sufficient  quantity. 
Dissolve  the  soap-shavings  in  three  pints  of  water  and  stand  aside. 
Dissolve  the  carbonate  of  ammonium  in  the  remainder  of  the  water, 
and  mix  the  two  solutions.  Then  add  the  camphor,  previously  re- 
duced with  alcohol  to  a  thin  paste,  and  agitate  briskly.  Oil  of  turpen- 
tine is  then  to  be  added  in  sufficient  quantity,  to  bring  the  mixture  to 
the  consistence  of  a  cream,  on  brisk  agitation  ;  after  which  the  tinc- 
ture of  opium  and  oil  of  origanum  are  to  be  added, — then  the  whole  is 
to  be  thoroughly  mixed. 
As  it  is  readily  absorbed  by  the  skin,  it  may  be  applied  by  the  hand, 
or  by  saturating  a  piece  of  flannel  and  placing  over  the  affected  part.

Preparation. — Procure  a  cylindrical  percolator,  having  a  height  of 
from  ten  to  twenty  times  its  diameter,  and  arranged  so  that  it  can  be 
maintained  at  a  temperature  of  about  150°  F.  by  a  steam  or  water- 
bath.  Introduce  a  diaphragm  having  about  300  perforations  to  the 
square  inch,  or  tie  a  coarse  cloth  over  the  nozzle.  Fill  the  percolater 
nearly  to  the  top  with  granulated  animal  charcoal.  Then  allow  the 
rectified  residuum  of  the  Smith's  Ferry  petroleum,  of  30°  Beaume
