440  Twenty-first  Annual  Meeting  of  the  {^oStS^"" 
following  morning,  and  this  afternoon  session  mainly  devoted  to  the 
reading  and  discussion  of  papers. 
Mr.  H.  N.  Rittenhouse  read  a  paper  in  answer  to  query  1,  on  a 
permanently  flexible  isinglass  plaster.  Mr.  P.  F.  Lehlbach,  in  an- 
swer to  No.  7,  presented  a  paper  on  Sapo  mollis,  accompanied  by 
some  samples. 
Dr.  Squibb  read  a  paper  on  rhubarb,  and  called  particular  atten- 
tion to  the  fact  that  even  the  best  rhubarb  of  commerce  appeared  to 
be  losing  that  peculiar  aromatic  odor  formerly  so  noticeable,  and 
which  he  considered  one  of  the  most  reliable  tests  of  the  root.  He 
accounted  for  this  by  suggesting  that  artificial  process  of  drying, 
forced  production,  &c,  might  be  the  causes.  He  submitted  three 
boxes  of  specimens  of  the  best  chests  that  had  been  imported  at  New 
York  the  past  year.  On  motion,  this  was  accepted  and  referred  for 
publication. 
Dr.  Squibb  also  read  an  essay  on  Physicians'  Pocket- Cases,  in 
which  he  described  one  of  his  own  contrivance,  provided  with  a  minim 
liquid  measure,  or  pipette,  to  draw  the  contents  from  the  vials  with- 
out dropping  or  pouring,  and  with  more  accuracy  than  by  either  of 
those  processes.  He  presented  specimens  of  the  cases,  &c,  and  an- 
nounced that  they  could  be  made  and  used  by  any  one  who  chose,  as. 
he  did  not  propose  to  patent  them. 
The  following  letter  was  read  by  the  Secretary  :
