out  with  hot  water  previous  to  using  them,  the  risk  is  lessened 
considerably. 
2d.  Syrups  filter  very  slowly.  The  hotter  the  syrup  is,  the 
quicker  it  runs  through ;  a  ribbed  funnel  or,  better,  interposing 
small  sticks  of  wood  or  glass  rods  between  the  filter  and  the  fun- 
nel quickens  filtration  a  good  deal. 
Syrupus  Zingiheris 
I  prepare  in  the  same  way,  that  is  to  say,  I  substitute  IJ  fluid- 
ounce  fluid  extract  of  ginger  for  6'fluidounces  tincture  of  ginger 
(both  representing  the  same  quantity  of  rad.  zingiber).  Of 
course,  I  follow  the  proportions  of  the  Pharmacopoeia. 
Campliorce  Pulv. 
Camphor  is  easily  enough  reduced  to  powder  by  rubbing  with 
a  few  drops  of  alcohol,  but  after  a  short  time  the  powder  will 
aggregate  to  crystals,  which  have  to  be  rubbed  down  again. 
I  reduce  camphor  to  a  fine  powder  as  above,  but  mix  it  then 
intimately  with  carbonate  of  magnesia  (10  grains  to  the  ounce  is 
sufficient,  but  even  20  grains  can  do  no  harm).  This  powder 
never  cakes  or  forms  crystals.*

TARTAR  EMETIC— AN  ANTHELMINTIC. 
By  J.  Dabney  Palmer,  M.  D. 
My  attention  was  directed  to  this  property  of  tartar  emetic  by 
observing  the  discharge  of  worms  in  several  cases  in  which  the 
medicine  had  been  employed  for  other  indications.  It  is  calcu- 
lated to  expel  the  round  worm  as  eifectually  as  the  tape. 
*  [The  idea  of  using  carbonate  of  magnesia  to  prevent  the  coalescing 
of  camphor  powder  was  suggested  several  years  ago  by  the  late  Henry 
P.  Fish,  in  a  paper  read  at  the  New  York  meeting  of  the  Association. 
(See  volume  for  1860.)  In  his  process,  a  drachm  of  the  magnesian  car- 
bonate was  used  to  disintegrate  16  ounces  of  camphor,  by"  dissolving  the 
latter  in  alcohol  and  pouring  the  solution  into  a  gallon  of  water  in  which 
the  magnesia  was  suspended,  and  letting  the  whole  settle  and  collect  in 
a  filter. — Edftor.]
