506     CRYSTALLIZATION  OF  SULPHO-CARBOLATE  OP  QUINIA. 
A  little  girl  of  5  years  was  threatened  with  inflammation  of 
the  brain,  for  which  two  or  three  doses  of  the  antimonial  were 
administered.  After  taking  the  last  dose  she  passed  a  large 
round  worm,  and,  as  no  anthelmintics  had  been  given,  the  result 
was  ascribed  to  the  antimonial. 
Mrs.  M.  gave  her  child  hive  syrup,  and,  in  order  to  induce  the 
child  to  take  it,  she  took  some  herself,  which  was  followed  by 
the  discharge  of  18  inches  of  tape  worm. 
These  worms  were  passed  alive,  owing,  in  all  probability,  to 
the  minute  quantity  of  tartar  emetic  taken.

CRYSTALLIZATION  OF  SULFHO-CARBOLATE  OF  QUINIA. 
By  C.  J.  Rademaker,  M.  D. 
Having  had  occasion  to  prepare  sulpho-carbolate  of  quinia, 
for  hospital  use  in  this  city,  the  following  process  was  resorted 
to: 
Crude  sulphocarbolic  acid  was  saturated  with  plumbic  carbo- 
nate, the  sulphocarbolate  of  lead  crystallized,  and  decomposed 
with  sulphate  of  quinine.  The  solution  of  sulphocarbolate  of 
quinine  filtered  and  evaporated,  but  it  was  found  almost  impos- 
sible to  crystallize  the  salt,  owing  to  the  gelatinous  condition  of
