These  facts  appear  to  point  to  an  abstraction  of  water  by  the  cam- 
phor, and  solution  of  the  latter  in  the  liberated  chloral ;  but  such  an 
avidity  for  water ,  is  not  shown  by  camphor  under  ordinary  circum- 
stances, and  the  cause  of  this  curious  liquefaction  is  not  easily  dis- 
cernible. 
[***  Some  time  since  the  Medical  Record  quoted  from  an  Ameri- 
can source  a  statement  that  if  camphor  be  powdered  by  rubbing  it  in 
a  mortar  with  a  few  drops  of  spirit,  and  an  equal  weight  of  chloral 
hydrate  added,  a  liquid  is  produced  which  is  a  valuable  local  anaes- 
thetic. Mr.  Lennox  Browne,  writing  to  the  British  Medical  Journal 
(March  7th,  p.  304),  confirms  this  statement,  and  says  that  it  is  of 
the  greatest  value  as  a  local  application  in  neuralgia.  Mr.  Browne 
having  employed  it  during  several  months,  has  found  great  and  some- 
times instantaneous  relief  to  follow  its  application  in  every  case.  It 
is  only  necessary  to  paint  the  mixture  lightly  over  the  painful  part 
and  allow  it  to  dry.  The  application  never  blisters,  though  it  may 
occasion  a  tingling  sensation  of  the  skin.  The  compound  has  also- 
been  found  of  great  service  in  the  relief  of  toothache. — Ed.  Phakm.

EXTRACT  OF  MEAT. 
By  C.  F.  Chandler,  Ph.  D.,  and  F.  A.  Cairns,  A.  M. 
The  following  analyses  were  made  for  the  purpose  of  determining,, 
as  fully  as  possible  by  analysis,  the  comparative  value  of  the  meat 
extract  made  by  the  "  Liebig  Company  "  (Fray-Bentos  Extract)  and 
that  made  at  the  "  San  Antonio  Meat  Extract  Factory."  The  most 
important  test  of  the  comparative  value  of  these  extracts  is  probably 
the  percentage  of  nitrogenous  matter  soluble  in  alcohol,  and  the  per- 
centage of  nitrogen  in  this  matter.  This  is  largely  due  to  the  fact 
that  gelatin  is  not  soluble  in  this  liquid.
