this  to  two  fluidounces  and  add  to  the  reserved  portion.  Filter,  add 
six  troyounces  of  white  sugar,  and  dissolve  by  aid  of  a  gentle  heat. 
The  above  extract  has  been  used  with  satisfaction  and  decided  re- 
sults in  the  dose  of  one-half  to  one  teaspoonful,  according  to  age. 
A  very  agreeable  syrup  may  be  prepared  from  the  extract  by  the 
following  formula:  Take  of  fluid  extract  four  fluidounces  ;  syrup  of 
vanilla,  eight  ounces  ;  simple  syrup,  sufficient  to  make  one  pint.  This 
is  used  in  the  dose  of  three  to  four  teaspoonfuls.  The  syrup  of 
vanilla  wholly  disguises  that  bitter  and  disagreeable  taste  that  is  so> 
objectionable  in  most  of  the  anthelmintics.

The  Powdering  of  Chlorates  is  usually  effected  in  a  mortar,  the 
salt  being  kept  moist  by  alcohol.  To  obtain  larger  quantities  of  chlo- 
rate, in  the  form  of  powder,  suitable  for  colored  fires,  A.  Gawalowski 
proposes  to  dissolve  the  chlorate  in  hot  water,  to  complete  saturation^ 
and  to  dip  into  the  solution  plates  of  glass,  which,  on  being  removed, 
become  covered  with  a  fine  crystalline  powder  of  the  salt,  which  is 
readily  collected  upon  paper  and  dried,  without  the  least  danger  to 
the  operator. — Pharm.  Cent.  Halle,  No.  24,  from  Journ.  f.  pr.

Alkaloid  in  Hojys. — In  1863,  Lermer  suggested  the  presence  of  a 
peculiar  alkaloid  in  hops.  Griessmayer's  recent  experiments  seem 
to  prove  the  existence  of  a  peculiar  volatile  alkaloid,  which  he  named 
lupulina.  The  concentrated  aqueous  decoction  of  ten  pounds  of  hops 
was  distilled  with  potassa  or  with  magnesia,  the  distillate  neutralized 
with  muriatic  acid,  evaporated  to  dryness,  treated  with  cold  absolute 
alcohol,  to  remove  sal  ammoniac,  the  alcoholic  liquid  heated  to  boil- 
ing and  cooled,  when  much  muriate  of  trimethylamina  crystallized. 
The  filtrate  was  evaporated  in  a  water-bath,  and  finally  spontane- 
ously, the  residue  redissolved  in  water,  in  a  narrow  cylinder,  agitated 
with  potassa  and  ether,  and  the  ethereal  solution  evaporated  sponta- 
neously. The  remaining  alkaline  liquid  had  a  peculiar  odor,  remind- 
ing of  conia,  and  a  cooling,  but  not  bitter  taste.  It  soon  separated 
small  crystals,  and  finally  solidified  completely.  The  author  supposes 
that  these  crystals  are  impurities,  and  that  the  pure  alkaloid  is  liquid
