E.  M.  Boring  exhibited  artificial  oil  of  bitter  almonds,  made  by  Dr.  F.  Wilhelmi, 
Reudnitz,  Leipsic,  of  which  he  is  the  inventor  and  only  manufacturer.  This  sub- 
stance is  not  to  be  confounded  with  mirbane  oil,  which  merely  smells  like  bitter 
almond  oil,  but  it  is  identical  as  well  in  its  composition  as  in  its  physical,  chemical 
and  physiological  properties  with  the  natural  oil  made  from  almonds,  and  has  the 
great  advantage  over  the  natural  oil  that  it  is  free  from  prussic  acid,  and  is  much 
cheaper. 
C.  W.  Hancock  exhibited  re-sublined  carbonate  of  ammonium  as  made  by  C.  T. 
White  &  Co.,  which  is  without  empyreumatic  odor ;  also,  solution  of  acetate  of 
ammonium  made  with  it,  and  pure  acetic  acid  from  the  same  firm.  From  long  ex- 
perience he  finds  it  very  grateful  to  the  sick  and  much  to  be  preferred  over  that 
made  fom  ordinary  commercial  articles — a  sample  of  which  was  likewise  shown  for 
comparison. 
Prof.  Bedford  was  asked  as  to  the  use  of  these  materials  in  New  York  ;  he 
agreed  with  Mr.  Hancock  as  to  the  advantage  of  the  solution  when  thus  prepared, 
but  would  confess  that  here,  as  there,  the  majority  of  apothecaries  were  not  aware 
of  these  facts ;  he  also  said  that  ammonium  carbonate  was  .now  made  near  New 
York  of  excellent  quality,  and  that  the  English  manufacturers  were  putting  down 
the  price  to  compete  for  the  trade. 
E.  M.  Boring,  having  tried  the  thick  filtering  paper  spoken  of  at  a  former  meeting, 
was  not  prepared  to  confirm  all  the  statements  made,  and  was  corroborated  by  Dr. 
Pile  who  thought  the  ordinary  round  filtering  paper  much  more  serviceable. 
Edward  Gaillard  found  the  solution  of  tartrate  of  sodium,  as  made  by  the  for- 
mula of  Mr.  Hayhurst  ("Amer.  Jour.  Phar.",  p.  208),  was  too  active  a  purgative, 
but  when  reduced  to  half  the  strength  answered  well.  There  is  a  demand  for  this 
preparation,  and  when  properly  labeled  and  sold,  will  give  satisfaction. 
Dr.  Pile  had  examined  a  number  of  starches  on  exhibition,  and  advised  the  use  of 
the  microscope  for  this  purpose.  He  found  the  globules  of  Jamaica  arrow  root  to 
be  of  the  same  shape  and  size  as  those  of  a  known  sample  of  St.  Vincent  arrow  root ; 
while  two  samples  of  St.  Vincent  arrow  root  obtained  from  New  York  gave  about 
three-quarters  of  Bermuda  arrow  root  and  one-fourth  of  tapioca  farina,  the  globules 
of  which  are  much  smaller  and  rounded;  other  samples  of  St.  Vincent  arrow  root, 
■obtained  in  this  city,  were  all  right. 
Adjourned  to  meet  August  15th,  1876,  at  3.30  P.M.
