answer  to  Query  26,  and  illustrated  the  subject  by  numerous  samples  of  the  prod- 
ucts in  various  stages  of  manufacture.  The  paper  is  not  adapted  for  condensation  5 
but  we  hope  to  be  enabled  to  publish  it  in  full. 
The  report  of  the  Committee  on  the  Next  Annual  Meeting  was  read  by  Mr. 
Eastman  ;  it  proposed  to  meet  next  year  in  Indianapolis,  on  the  second  Tuesday  in 
June.  After  some  discussion  the  report  was  adopted  with  the  amendment  that  the 
meeting  be  held  on  the  second  Tuesday  of  September. 
Mr.  Lloyd  exhibited  a  number  of  samples  of  resin  of  podophyllum,  and  read  a 
paper  on  the  same  subject  in  answer  to  Query  27.  It  conveys  the  information  that 
a  very  light-colored  resin  may  be  obtained  by  precipitating  the  tincture  with  pure 
cold  water  and  drying  the  precipitate  in  the  cold.  A  solution  of  alum  added  to  the 
water  imparts  a  greenish-yellow  color  to  the  resin;  the  use  of  heat  during  precipi- 
tation and  drying  darkens  the  color,  and  with  common  water  different  shades  of 
color  are  obtained,  according  to  the  saline  matter  dissolved  in  the  water. 
A  paper  by  J.  L.  Lemberger,  in  answer  to  querv  29,  on  a  liquid  preparation  of 
lactucarium,  and  illustrated  by  various  specimens,  was  read.  It  proposes  a  fluid 
extract  of  lactucarium,  to  be  made  by  beating  16  troyounces  of  lactucarium, 
depriving  it  of  caoutchouc  and  lactucerin,  by  treatment  with  32  fluidounces  of 
petroleum  benzin,  after  drying,  powdering  it  with  an  equal  bulk  of  sand,  and 
exhausting  it  in  a  percolator  with  diluted  alcohol.  The  first  four  fluidounces  are 
reserved;  the  remainder  is  distilled  and  evaporated  to  10  fluidounces,  filtered,  and 
the  filter  washed  with  sufficient  diluted  alcohol  to  make  the  whole  fluid  extract 
weigh  16  troyounces.  By  mixing  one  troyounce  of  this  fluid  extract  with  sufficient 
diluted  alcohol  to  make  8  fluidounces,  tincture  of  lactucarium  is  obtained,  and  on 
mixing  the  same  quantity  with  sufficient  simple  syrup  for  16  fluidounces,  a  nearly 
transparent  syrup  of  lactucarium  may  be  made,  having  all  the  bitter  taste  of  the 
officinal  syrup. 
Mr.  Lloyd  read  a  paper  in  answer  to  query  43,  on  tinctures  prepared  with  fresh 
plants.  The  author's  experience  is  in  favor  of  tincturing  plants  containing  essential 
oils  while  fresh.  Other  plants  may  be  partially  dried,  but  complete  drying  previous 
to  exhausting  them  appears  to  dissociate  some  of  the  active  principles.  A  tincture 
prepared  from  undried  veratrum  viride  was  found  to  be  an  inferior  preparation,  but 
when  the  root  was  recently  dried,  the  tincture  prepared  from  it  had  the  proper 
effects. 
A  paper  by  Prof.  Sharpies,  in  answer  to  query  48,  on  distinguishing  the  cinchona 
alkaloids,  elicited  some  discussion,  it  being  maintained  that  from  the  recently 
precipitated  alkaloids,  even  in  the  presence  of  a  large  excess  of  cinchonia,  all  the 
quinia  and  quinidia  may  be  readily  extracted  by  ether,  together  with  cinchonidia 
and  some  cinchonia,  and  that  the  undissolved  portion  does  not  show  the  thalleioquin 
reaction  with  chlorine  water  and  ammonia. 
An  adjournment  was  had  until  2.30  P.M.
