GLEANINGS— CHEMICAL,    PHARMACEUTICAL,  ETC.  V25 
Make  a  mass  with  these  ingredients,  roll  out  and  divide  into 
sixty  lozenges,  each  of  which  will  contain  two  grains  of  santonin. 
They  should  be  sprinkled  with  powered  sugar,  and  placed  in  a 
position  favorable  for  drying.  By  omitting  the  chocolate  and 
liquorice,  the  lozenges  will  be  white,  and  may  be  flavored  with 
vanilla,  or  in  any  way  most  agreeable. 
Charcoal  biscuits. — Dr.  Charles  Warren,  of  Boston,  recom- 
mends a  biscuit  of  charcoal,  each  containing  fifteen  grains  of 
that  substance,  as  a  palatable  means  of  administering  that  sub- 
stance in  dyspepsia. 
Vaccine  virus  in  a  fluid  state. — Dr.  J.  Hutson  Ford,  of 
Charleston,  S.  C,  preserves  vaccine  virus  in  its  normal  fluid 
condition  by  drawing  it  into  a  tube  open  at  both  ends,  and  then 
closing  the  ends  hermetically. 
Bl-SULPHURET  OF  CARBON,  AS  A  SOLVENT  FOR  CUBEBS. — M, 
Berjot,  of  Caen,  proposes  the  use  of  bi-sulphuret  of  carbon  to 
make  oleoresin  of  cubebs.  Messrs.  Garot  and  Schasseffele,  on 
reporting  on  his  paper,  give  the  preference  to  ether  as  a  men- 
struum for  this  purpose,  because  it  requires  less,  and  affords  a 
better  and  more  aromatic  product.  The  latter  mode  of  making  the 
extract  has  been  in  vogue  here  for  ten  years  past,  and  is  adopted 
in  the  U.  S.  Pharmacopoeia. 
On  a  mode  of  using  Chlorine  as  a  disinfectant. — M.  Lam- 
bossy  proposes  to  employ  a  mixture,  analogous  to  that  of  the 
Edinburgh  Pharmacopoeia,  for  making  chlorine  water,  as  a  source 
of  chlorine  as  a  disinfectant. 
In  a  bottle  holding  a  quart  he  puts  two  table-spoonfuls  of 
common  table  salt,  two  tea-spoonfuls  of  red  lead,  and  fills  the 
bottle  nearly  full  with  water.  Half  a  wine-glass  full  of  sulphuric 
acid  is  then  gradually  added  to  the  mixture,  with  frequeni 
shaking.  The  reaction  results  in  liberating  the  chlorine,  which 
dissolves  in  the  water.  When  its  effects  are  desired,  a  little  of 
the  solution  is  poured  upon  a  plate,  the  size  of  which  should  be 
proportioned  to  the  need,  when  the  chlorine  is  slowly  evolved. 
Researches  on  Arsenic. — Dr.  Blondlot,  of  Nancy,  has  just- 
observed  an  important  fact  in  connection  with  the  search  after 
arsenic  when  mixed  with  organic  matters.    When  substance?
