ON  SYRUPUS  CALCIS. 
By  Dr.  E.  R.  Squibb. 
In  a  communication  Dr.  Buckingham  says  : 
"  I  enclose  a  letter  from  Dr.  Squibb,  of  New  York,  which  I 
received  with  some  lime  prepared  with  sugar.  I  trust  that  those 
who  have  undertaken  to  make  the  syrup  and  failed,  will  not  be 
discouraged.  I  must  caution  against  the  use  of  the  article  in 
pill  or  dissolved  in  wTater,  as  it  will  produce  nausea,  or  even  a 
caustic  effect.  It  should  be  given  in  milk.  I  have  used  it 
in  doses  as  large  as  forty-five  drops  every  two  hours.  Generally, 
thirty-drops  every  three  hours  have  been  sufficient.  I  have 
never  found  alkaline  urine  to  follow  its  use,  no  matter  how 
large  nor  how  frequent  the  dose."

Dr.  C.  E.  Buckingham,  Boston. 
Dear  Sir, — Your  paragraph,  on  the  back  of  the  reprint  from 
the  Boston  Medical  and  Surgical  Journal,  came  duly  and  has 
occupied  me  ever  since,  though  it  gave  you  little  trouble  to  write. 
On  the  authority  of  the  books  generally,  I  did  not  know  whether 
you  or  they  were  wrong,  and  to  determine  this  had  to  go  over 
the  subject  practically.  I  will  not  trouble  you  nor  take  up  my 
time  with  any  detail,  but  give  you  the  results  to  use  as  you  see 
proper.  Sucrate  of  lime  is  a  very  definite  thing  chemically, 
and  is  soluble  to  any  extent  in  solutions  of  sugar.  To  make  it, 
it  is  only  necessary  to  have  lime,  either  caustic  or  hydrated,  no 
matter  which,  associated  with  about  three  times  its  weight  of 
sugar  ;  but  to  render  it  soluble  an  additional  proportion  of  sugar 
is  necessary.  The  best  proportion,  practically  arrived  at,  was 
one  part  caustic  lime  (or  two  parts  hydrate  or  slaked  lime),  with 
eight  parts  of  dry  white  sugar,  rubbed  together  and  poured  into 
teti  parts  of  boiling  water,  and  boiled  a  few  minutes  ;  then  dilu-
