Administration  of  Castor  Oil — M.  Perschne  recommends  an  emulsion 
prepared  from  15  grams  of  castor  oil  with  one  yolk  and  45  grams 
Walter,  which,  after  the  addition  of  about  10  grams  of  brandy  or  sherry 
wine,  is  taken  in  lemonade. — Phar.  Zeitsch.f.  RussL,  1881,  p.  398. 
Disguising  the  Odor  of  Iodoform. — In  discussing  the  value  of  the 
different  substances  recommended  for  this  purpose  Hager  states  that 
the  activity  of  iodoform  depends  upon  the  gradual  liberation  of  iodine, 
and  that  the  addition  of  all  substances  should  be  avoided  which  enter 
into  combination  with  iodine.  Hence  all  drugs  containing  tannin 
should  be  discarded ;  even  balsam  of  Peru  resorbs  much  iodine,  and 
should  never  be  used  in  larger  proportion  than  1  part  to  10  parts  of 
iodoform.  Volatile  oils  of  anise,  fennel,  peppermint,  etc.,  appear  to 
be  the  most  useful,  only  1  part  of  these  to  20  parts  of  iodoform  being 
necessary. — Phar.  Centralhalle,  1881,  No.  12. 
Tonka  bean,  the  seed  of  Dipterix  odorata,  has  been  recommended  for 
the  same  purpose  by  V.  Mosetig.  The  seed  which  contains  coumarin, 
entire  or  split  longitudinally,  is  placed  into  a  bottle  containing  from 
150  to  200  grams  of  iodoform  ;  the  latter  loses  its  peculiar  odor  in  a 
short  time,  which  is  replaced  by  a  faint  bitter  almond  odor.  Or  the 
iodoform  may  be  rubbed  up  with  a  small  quantity  of  the  alcoholic  or 
ethereal  extract  of  tonka. — Allg.  Wien.  Zeit,  June  14. 
Tannate  of  chinoidin  is  prepared  by  Reiher  and  Klamann  by  dilut- 
ing 100  grams  of  tincture  of  chinoidin  (chinoidin  2  parts,  alcohol  17 
parts,  hydrochloric  acid  1  part)  with  500  grams  of  water  and  adding  a 
solution  of  50  grams  of  tannin  in  1,000  grams  water,  and  subsequently 
a  solution  of  ammonium  acetate.  After  10  hours  the  precipitate  is  col- 
lected, Avashed  and  dried  at  a  temperature  not  exceeding  30°C.  (86°F.) 
It  is  of  a  yellowish-brown  color,  tasteless,  and  yields  with  cold  water, 
on  the  addition  of  a  little  hydrochloric  acid,  a  dark  yellow  solution. 
The  dose  to  small  children  is  0*5  to  I'Ogram  (gr.  viii  to  xv). — Phar. 
Centralhalle,  1881,  p.  273. 
Folder'' s  Solution. — The  algaceons  growth  frequently  observed  in 
this  solution  is  entirely  prevented,  according  to  Perschne,  by  replacing 
one-fourth  of  the  water  with  glycerin. — Phar.  Zeitsch.f.  Russlandj  188  J , 
p.  397.
