iron  published  anywhere.  Prof.  Maisch  stated  such  a  tincture  might  be  readily 
made,  but  was  neither  officinal  in  the  French  or  German  Pharmacopoeia,  the 
latter  directing  an  aqueous  solution  of  spec.  grav.  1*23  ;  ferrous  chloride  was  rather 
less  freely  soluble  in  alcohol  than  ferric  chloride.1  ' 
A  formula  for  Cremers  Pomade  was  asked  for  5  the  preparation  was  referred  to  in 
"  Braithwaite's  Retrospect,"  Jan.,  1S78,  p.  198,  as  an  application  to  the  eye,  but 
without  giving  the  formula,  which  could  also  not  be  found  in  a  number  of  works 
that  were  consulted. 
A  member  called  the  attention  of  the  meeting  to  a  statement  in  some  of  the  daily 
papers  relative  to  a  new  industry  which  has  been  lately  developed  in  Pottsville,  Pa., 
that  of  distilling  the  oils  of  Gaultheria  and  several  other  native  plants,  the  children 
gathering  the  crude  drugs  and  bringing  them  to  those  who  have  commenced  the 
distillation  of  the  oils. 
In  answer  to  an  inquiry  for  the  formula  for  nigrosine  ink,  it  was  stated  that  two 
formulae  were  published  in  "Araer.  Jour.  Phar.,"  1875,  P«  88,  and  1876,  p.  545  it 
seems  to  possess  the  advantage  that  it  penetrates  the  texture  of  the  paper,  and  a 
label  that  has  been  written  with  it,  when  pasted,  does  not  become  smeared  by  the 
necessary  handling  when  being  rubbed  smooth  upon  the  bottle.  This  ink  seems  to 
be  more  permanent  than  other  anilin  inks,  which  usually  fade  on  exposure.  Eosin 
(a  very  brilliant  scarlet)  ink  is  also  made  from  an  anilin  color,  the  name,  however, 
is  improperly  applied,  the  word  meaning  merely  rosy-colored,  not  scarlet.  Some 
remarks  were  made  about  writing  inks  which  would  not  be  removed  by  either  acids 
or  alkalies,  and  it  was  stated  that  the  object  could  be  attained  by  adding  to  a  nut- 
gall  ink  some  solution  of  indigo,  or  a  solution  of  soluble  Prussian  blue  5  the  latter 
compound  is  obtained  by  precipitating  a  ferric  salt  with  an  excess  of  ferrocyanide  of 
potassium,  decanting  the  mother  liquor,  and  washing  the  precipitate  with  water 
until  it  becomes  soluble  therein. 
Prof.  Maisch  exhibited  a  specimen  of  Java  cinnamon,  it  resembled  the  variety 
that  came  in  the  market  some  years  ago  as  Chinese  cassia,  but  was  a  much  thinner 
bark,  and  appears  to  be  obtained  from  Cinnamomum  Zeylanicum,  grown  in  Java, 
and  not  deprived  of  its  suberous  layer.

branch  and  written  answers  required  to  the  following  questions:

i .  What  sulphates  of  the  heavy  metals  (Sp.  Gr.  over  6)  are  officinal  in  the  U.  S.  P.  ? 
Give  the  method  of  preparation  of  each  and  explain  the  reactions  which  take  place, 
lHager  directs  the  tincture  to  be  made  by  mixing  8  parts,  each  of  alcohol  and  solution  of  ferrous 
chloride,  and  adding  i  part  of  simple  syrup. — Editor.
