made  use  of  the  preparation  as  a  remedy  in  a  case  of  acid 
dyspepsia  with  great  resulting  advantage.  Since  then  he  has 
seen  it  tried  by  others,  by  Dr.  Mitchell,  for  instance,  with  suc- 
cess. Dr.  Capitaine,  of  Paris,  however,  had  made  the  same  ap- 
plication before  the  writer  had  thought  of  it,  although  the  first 
notice  the  writer  saw  of  it  was  a  note  appended  to  the  article 
Aqua  Calcis  in  the  U.  S.  Dispensatory.  Dr.  Capitaine  also  used 
it  successfully.  The  writer,  although  being  behind  hand  in  his 
application,  determined,  at  least,  to  investigate  some  of  the  pro- 
perties, &c,  of  a  solution  of  lime  in  syrup. 
First. — To  «  Syrupus,'  U.  S.  P.,  two  parts  of  water  were  added, 
and  the  syrup  resulting  was  poured  upon  fresh  unslaked  lime  in 
a  bottle,  and  allowed  to  stand  four  summer  months.  No  heat 
was  applied.  At  the  end  of  this  time,  the  syrup  being  perfectly 
clear,  a  quantity  was  removed  by  a  pipette.  This  syrup  was 
sherry-colored,  alkaline  in  reaction,  calcareous  in  taste,  and 
smelt  slightly  of  metacetone.  One  fluid-ounce  was  carefully  burnt 
in  a  crucible,  and  the  ashes  dissolved  in  dilute  acid.  The  lime 
present  precipitated  by  oxalate  of  ammonia,  collected  on  a  filter., 
washed,  burnt  and  weighed  as  carbonate.

This  would  give  about  20.5  of  hydrate  of  lime  in  f.gi. 
Second. — 4  Syrupus'  was  added  to  lime  in  a  bottle,  and  allowed 
to  stand  three  weeks.  The  syrup  filtered  off  at  the  end  of  this 
time  was  strongly  alkaline,  calcareous  in  taste,  dark  sherry  in 
color,  and  rather  thick.  Took  f.^ss.  and  burnt,  conducting  the 
process  as  in  the  first  experiment.

This  is  nearly  2  grs.  of  carbonate  in  the  half  ounce,  or  nearly 
3  grains'of  hydrate  of  lime  in  the  ounce. 
Third. — Boiled  some  lime  with  <  Syrupus/  filtered  while  hot, 
obtaining  a  syrup  dark  brown  in  color,  very  thick,  smelling 
strongly  of  metacetone,  slightly  calcareous  and  alkaline.  A
