experienced  during  its  service,  and  it  was  thought  best  to  use  one  of 
carbolic  acid,  which  I  prepared  from  the  following  formula  : 
R        White  wax,       .       .       .       .        .    ^i     =  grains  31*1 
Lard  (very  best),    '.  ^viii  =  grams  248*8 
Carbolic  acid  (crystal),      .        .        .    gr.xii  =  grams  078 
Misce. 
The  lard  and  wax  were  first  melted  on  a  water  bath,  then  adding 
the  carbolic  acid,  the  whole  was  allowed  to  cool  under  constant  stir- 
ring, and  applied  as  often  as  the  wound  was  dressed,  first  thrice  and 
afterwards  twice  a  day. 
It  has  indeed  proved  so  satisfactory  for  the  case  it  was  used  that  I 
thought  it  worth  a  notice  in  our  "Journal,"  as  nothing  else  was  used 
but  just  the  salve,  though  some  warm  weather  prevailed  here  during 
that  time;  and  after  a  duration  of  six  weeks  the  patient  was  enjoying 
the  free  air  as  much  as  any  of  us.  It  may  be  well  to  add  that  in  very 
warm  weather,  one  ounce  of  the  lard  should  be  exchanged  for  one  of 
wax,  otherwise  it  would  be  too  soft  for  use. 
Respectfully,  C.  F.  Wish.

Reactions  of  Alkaloids.— R.  Goddefroy  has  observed  the  following 
reactions : 
1.  Ferric  chloride  dissolved  in  muriatic  acid  produces  with  not  too 
diluted  solutions  of  alkaloids  in  the  same  acid 
Yellowish -red  precipitates  :  Precip.  soluble  in  excess  :  No  precipitates: 
Aconitia,  piperina,  strychnia,      Atropia,  quinia,  cinchonia.        Brucia,  caffeina, 
veratria.  morphia. 
The  precipitates  contain  one  molecule  of  ferric  chloride,  combined 
with  two  molecules  of  the  alkaloidal  hydrochlorate  ;  the  quinia  double 
salt  may  be  obtained  in  small  prisms  by  evaporating  the  acid  solution, 
is  freely  soluble  in  water  and  alcohol,  and  possesses  a  bitter  and  inky  taste. 
2.  Antimony  trichloride  dissolved  in  muriatic  acid,  with  solutions  as 
before, 
Precipitates  from  rather  dilute  solutions:         From  concentrated      No  precipitates : 
solutions : 
Aconitia,  quinia,  cinchonia,  conia,  piper-    Atropia,  nicotina,      Caffeina,  morphia, 
ina,  strychnia,  veratria.  solania.
