PHARMACEUTICAL  GLEANINGS.  2 13 
Flies  are  attracted  by  this  liquid  and  are  soon  killed  by  it. — Ibid, 
Dec.  1852. 
HainauVs  Dentifrice. — Powdered  tormentilla  80  parts, powdered 
orris  root  40  parts,  cream  of  tartar  20  parts,  fused  chloride  of 
calcium  4  parts.  Reduce  the  chloride  rapidly  to  powder  and  mix 
it  with  the  other  ingredients. 
Insolubility  of  Alum  in  Brandy. — Physicians  sometimes  direct 
a  mixture  of  alum  and  brandy  as  a  bath.  When  100  grains  of 
powdered  alum  are  macerated  for  several  days  in  1000  grains  of 
French  brandy,  sp.  gr.  947°,  the  filtered  liquid  contains  hardly 
a  trace  of  the  salt,  as  100  grains  of  it  on  evaporation  yielded  less 
than  half  a  grain  of  extract-like  matter  with  but  little  taste  of 
alum.  W.  P.,  Jr. 
Bottle  for  Dropping  Liquids. — Mr.  George  Dymond,  of  Man- 
chester, England,  suggests  a  decanter-shaped  bottle  with  a  hollow 
stopper  of  peculiar  construction  for  dispensing  liquids  by  drops. 
The  bore  of  the  stopper  follows  its  axis  until  above  the  lip  of  the 
bottle,  when  it  divides  to  the  right  and  left  so  as  to  produce  two 
apertures  parallel  with  each  other,  one  of  these  being  much  larger 
than  the  other.  When  the  bottle  is  filled  with  a  liquid  and  in- 
clined with  the  small  aperture  down,  "  a  perfectly  regular  succes- 
sion of  drops  of  uniform  size  escape,  the  air  being  at  the  same 
time  admitted  through  the  opposite  aperture.  The  position  of  the 
bottle  being  reversed,  a  larger  supply  of  liquor  is  obtained  by  means 
of  the  large  aperture  of  the  stopper,  whence  it  issues  in  a  moderate 
and  uniform  stream." 
The  author  considers  this  bottle  particularly  valuable  in  refer- 
ence to  volatile  liquids,  like  ethereal  solutions,  hydrocyanic  acid, 
etc.,  where  loss  by  evaporation  is  liable*  to  occur.  There  is  a 
glass  cap  to  cover  the  top  of  the  bottle,  ground  to  fit  the  lip,  which 
prevents  evaporation  when  the  bottle  is  not  in  use,  and  adapts  it 
for  holding  test  liquids. — Pharm.  Journ.,  March,  1853. 
Remedy  for  the  Sting  of  Bees. — M.  Gumprecht  recommends 
the  expressed  juice  of  the  honeysuckle  (Lonicera  caprifolium)  as 
a  remedy  for  the  stinging  of  bees.  The  stung  place  is  to  be  rubbed 
with  the  juice,  which  may  be  kept  in  closely  stopped  bottles  for 
this  purpose. — Chem.  Gaz.}  Jan.  15.
