Decolorized  loeline. — Sulphurous  acid  being  used  to  some  extent  for 
decolorizing  tincture  of  iodine,  S.  A.  McDonnell  suggests  to  prepare  an 
aqueous  solution  of  the  same  iodine  strength  as  the  tincture,  by  triturating 
iodine  ^ss,  dissolving  it  in  sulphurous  acid  ^iiss,  and  diluting  with  water 
to  obtain  1  tiuidounce.  The  liquid  is  colorless,  and  contains  hydriodic  and 
dithionic  acids.  A  strong  solution,  in  which  one-half  of  the  iodine  remains 
in  the  free  state,  is  obtained  by  dissolving  200  grains  of  iodine  in  1  ounce  of 
sulphurous  acid.  It  is  of  a  rich  dark  red  color,  and  can  be  diluted  to  any 
extent  with  alcohol  or  glycerin,  or  both,  but  not  with  water,  which  causes 
a  jirecipitation  of  the  iodine. 
Fluid  Magnesia.  — F.  L.  Vreeland  shows  that  the  process  for  solution  of 
carbonate  of  magnesium,  Brit.  Ph.,  is  unfeasible  for  the  pharmacist,  and 
incapable  of  being  more  simplifted,  even  with  an  apparatus  simple  in  con- 
struction and  easily  managed.  A  superior  product  in  every  respect  is  the 
officinal  liquor  magnesii  citratis. 
Substitute  for  Veiseline. — P.  L.  Vreeland  recommends  the  process  for 
niollisine  recommended  by  Wm.  C.  Bakes  (this  journal,  1880,  p.  9),  but 
found  it  necessary  to  deodorize  the  spindle  oil,  which  was  accomplished  by 
spreading  it  ui)on  a  wide  expanse  of  water,  and  boiling  for  some  time.  One 
gallon  of  spindle  oil  will  yield  four  pounds  of  the  purified  product,  and  with 
1  lb.  of  yellow  wax  will  make  the  cost  80  cts.  per  lb. 
Liquor  Ferri  et  Ammonii  succincitis. — Prof.  W.  T.  Wenzell  recommends 
the  following:  Dissolve  50  grains  of  succinic  acid  in  3  fluidounces  of  water, 
neutralize  nearly  with  ammonia,  and  dilute  to  (3  fluidounces.  Transfer  to 
an  8oz.  bottle,  add  half  a  tiuidounce  of  the  officinal  liquor  ferri  persulphatis, 
agitate  well,  and  wash  the  j^recipitated  ferric  succinate  upon  a  filter 
thoroughly  with  distilled  water. 
Next  take  89  grains  of  citric  acid  and  add,  with  stirring,  a  sufficient 
quantity  of  ammonia  until  the  acid  is  dissolved  and  the  solution  neutral. 
In  this  solution  dissolve  the  moist  ferric  succinate  with  the  aid  of  a  gentle 
heat,  and  dilute  to  6  fluidounces,  when  each  fluidrachm  will  contain  2 
grains  of  ferric  succinate,  or  e5  grains  of  the  double  salt. 
Syrupus  Scillce  comjj.—V.  L.  Vreeland  recommends  a  modification  of  the 
Pharmacopoeia  process  as  follows :  To  8  oz.  of  fluid  extract,  obtained  by 
evaporating  the  tincture  of  squill  and  senega,  add  6  oz.  of  lime  water  and 
4  oz.  of  distilled  water;  allow  to  stand  for  12  hours,  filter,  and  in  the 
filtrate  dissolve  without  heat  40  oz.  of  granulated  sugar ;  lastly,  dissolve 
48  grains  of  tartar  emetic  in  I  oz.  distilled  water,  add  to  the  syrup,  and 
bring  the  measure  up  to  three  pints  by  adding  heavy  rock  syrup. 
Annual  Revieu^  of  the  Drug  Trade  of  New  York  for  the  year  1880.  By 
Daniel  C.  Bobbins.  1881. 
This  has  been  j^repared  for  the  twenty-third  annual  report  of  the  Cham- 
ber of  Commerce  of  the  State  of  New  York.    The  total  importation  of 
drugs,  chemicals,  oils,  soaps  and  spices  was,  in  1880,  $48,073,158,  against 
.$36,008,208  in  1879.
