Extractum  Anthemidis  Fluidum. 
At  the  request  of  a  medical  friend,  who  has  a  high  opinion  of 
the  antiperiodic  power  of  Chamomile  in  certain  cases  of  obstinate 
ague,  we  prepared  a  concentrated  solution  of  the  flowers  preserved 
by  sugar  and  alcohol,  of  the  strength  of  thirty  grains  to  the  tea- 
spoonful,  by  the  following  recipe  : — 
Take  of  Chamomile  flowers,  eight  ounces  (troy.) 
Sugar,        -        -  eight  ounces. 
Alcohol, 
Diluted  alcohol,  of  each    a  sufficient  quantity. 
Bruise  the  chamomile  thoroughly,  pour  on  it  a  pint  of  alcohol 
and  macerate  for  twenty-four  hours,  pack  it  moderately  tight  in 
a  percolator,  and  pour  on  slowly  diluted  alcohol,  until  a  pint  of 
liquid  has  passed*  then  change  the  recipient,  and  continue  the 
process  until  two  pints  more  of  tincture  are  obtained.  Evaporate 
the  first  tincture  by  a  gentle  heat,  or  spontaneously  to  six  fluid 
ounces,  and  the  other  in  a  water  bath  to  four  fluid  ounces,  mix 
the  liquids,  add  the  sugar  to  them,  dissolve  by  a  gentle  heat,  and 
finally  add  alcohol  until  the  whole  measures  a  pint. 
The  dose  of  this  preparation  is  from  one  to  two  teaspoonfuls 
as  an  antiperiodic,  or  half  a  teaspoonful  as  a  tonic.

Poisoning  by  Helvella  esculenta. 
Dr.  E.  Hamburger,  of  Bromberg,  describes  a  case  of  poisoning 
by  Helvella  esculenta,  (common  morell,)  which  occurred  to  a 
forest  inspector,  his  wife  and  six  children.  The  first  symptoms, 
observed  on  the  day  following  the  partaking  of  the  morells,  were 
headache,  nausea,  vomiting,  with  pains  in  the  belly;  the  sick 
took  milk  as  an  antidote,  which  proved  unavailing,  and  24  hours 
after  the  poisoning  a  physician  was  called,  who  ordered  castor 
oil,  oily  clysters  and  cold  fomentations  to  the  head.  On  the 
next  day  Dr.  H.  was  called,  who  found  the  three  youngest  chil- 
dren dead,  the  three  others,  between  10  and  15  years,  suffering 
with  the  following  symptoms  :    Somnolency,  but  not  difficult  to
