in  their  places.  We  have  found  this  invaluable  in  the  relief  of 
such  disturbances  as  are  not  dependent  on  fully  developed  in- 
flammation, such  as  neuralgic  disturbances,  and  the  first  stages 
of  periostitis.  A  more  powerful  liniment  can  be  made  by  taking 
one  part  of  white  of  an  egg  and  four  of  chloroform,  placing 
them  in  a  bottle,  which  is  to  be  completely  plunged  into  a  water- 
bath  at  from  120°  to  140^.  Gelatinization  takes  place  in  four 
minutes.  This  is  to  be  rubbed  on  any  painful  part,  and  great 
relief  is  produced.  The  slow  cauterization  it  gives  rise  to,  and 
the  protection  of  the  part  from  the  atmosphere,  render  it  a  very 
powerful  counter-irritant.  The  cold  preparation  is  perhaps  the  best 
and  easiest  made,  and  when  a  decided  effect  is  required,  it  should 
be  repeatedly  used. — London  Pharm.  Journ.  Aprils  1861,/rom

It  is  generally  known  that  bitter  almonds,  being  introduced 
in  a  potion  along  with  musk,  will  destroy  almost  entirely  the 
odor  of  the  latter.  Syrup  of  orgeat,  water  distilled  from  the 
cherry  laurel,  and  all  the  cyanogen  compounds,  produced  the 
same  effect.  Many  apothecaries  are  accustomed  to  clean  their 
mortars,  when  used  for  the  trituration  of  musk,  by  rubbing  in 
them  the  wet  paste  which  remains  as  a  residue  in  the  prepara- 
tion of  emulsions.  Lately,  the  distilled  cherry-laurel  water 
has  been  prepared  for  the  disinfection  of  sores  by  Dr.  Autier," 
of  Anliens. 
Cod-liver  oil  has  been  purified  by  means  of  the  essential  oil  of 
Mirbane,  which  is  nothing  else  than  nitrobenzine,  in  the  propor- 
tion of  two  thousandths.  This  plan  has  even  been  the  object 
of  a  patent  obtained  by  a  Paris  pharmaceutist.  The  addition 
has,  however,  two  inconveniences ;  the  introduction  in  the  oil  of 
a  substance  whose  action  on  the  animal  economy  is  injurious,  and 
the  protection  of  the  patent. 
The  above  considerations  lead  me  to  attempt  to  purify  and 
perfume  cod-liver  oil  and  castor  oil  by  means  of  the  cyanogen 
compounds.    After  a  series  of  experiments,  I  have  determined
