solution  of  acetate  of  uranium,  8-gram  do.  of  proto-acetate  of  copper. 
5-gram  do.  of  acetate  of  morphia,  10-gram  do.  of  formate  of  copper, 
20-gram  do.  of  tannate  of  iron.  These  deposits  invariably  take  place 
on  that  part  of  the  bottle  most  exposed  to  light.  This  phenomenon  may 
be  due  to  heat,  but  deposits  or  films  occur  in  some  solutions  within  the 
liquid  as  well  as  above  it — especially  noticeable  with  tannate  of  iron,  the 
film  of  which  adheres  strongly  to  glass. — Amer.  Chem.,  Oct.,  1876.

VARIETIES. 
Ergot  for  Hypodermic  Use. — At  the  last  meeting  of  the  American  Pharmaceu- 
tical Association,  Mr.  D.  Benjamin  stated  that  a  liquid  preparation  of  ergot, 
prepared  by  the  following  formula,  had  been  used  with  advantage  by  several  physi- 
cians, among  others  by  Profs.  Agnew  and  Goodell,  of  the  University  of  Pennsyl- 
vania :  Two  troyounces  of  powdered  ergot  are  exhausted  by  8  fluidounces  of 
strong  alcohol,  the  tincture  is  evaporated,  at  a  low  temperature,  to  2  fluidounces  ; 
when  cold,  mixed  with  6  fluidounces  of  water,  filtered,  again  carefully  evaporated 
to  two  fluidounces,  and  preserved  by  the  addition  of  3  grains  of  salicylic  acid. 
Mr.  Benjamin  has,  since  then,  evaporated  the  liquid  to  one  fluidounce  and  added  two 
grains  of  salicylic  acid  for  preservation. 
Ergot  for  Hypodermic  Injection. —Having  been  requested  to  devise  a  suitable 
preparation  of  ergot  for  the  above  purpose,  H.  P.  Madsen,  in  default  of  Dragen- 
dorfPs  sclerotic  acid,  dissolved  the  officinal  extract  of  ergot  in  equal  weight  of 
diluted  alcohol  (0-890),  filtered,  after  3  day's  repose,  and  evaporated  to  sp.  gr.  1*25. 
The  liquid  is  now  accurately  saturated  with  carbonate  of  sodium  and  is  ready  for 
use.  (Extr.  of  ergot,  "  Ph.  Dan.,"  is  made  by  exhausting  with  water,  evaporating 
to  syrupy  consistency,  mixing  with  diluted  alcohol  [0*890],  filtering  and  evaporating 
to  extract  consistency). — H.  M.  W.  from  Ny  Pharm.  Tid.,  1876,  p.  372. 
Gregory's  Syphon  Filter.— ("  Proceedings  Am.  Phar.  Ass.,"  1876,  p.  56.)  Mr. 
G.  cautions  against  too  strong  suction,  lest  the  filtering  paper  be  broken.  This 
can  be  prevented  by  first  stretching  a  piece  of  not  too  fine  muslin  over  the  tube, 
and  over  the  muslin  tying  the  filtering  paper.  Be  the  suction  ever  so  strong,  the 
paper  will  be  prevented,  by  the  muslin,  from  being  stretched  to  breaking.

Diaetheralysis  of  Legrip.—  [Ibid.,  p.  61.)  This  is  nothing  new,  at  least  the 
writer  cannot  find  any  difference  between  Legrip's  method  and  that  of  Pierlot 
("Am.  Jour,  of  Phar.,"  1862  [xxxiv],  p.  544.)  Hans  M.  Wilder.
