sfatemeut  that  proof  spirit  had  the  specific  gravity  '9198,  he  thought  that 
possibly  the  strength  might  have  been  changed  by  law,  and  had  applied  to 
Mr.  Pile  for  information.  There  were  other  shortcomings  in  the  tables 
admitted  into  the  PharmacoiDoeia  without  a  word  of  explanation;  in  this 
country  it  was  customary  to  express  the  specific  gravity  of  liquids  by  com- 
paring their  weight' at  15°  or  15-6° C  (59°  or  60° F.)  with  the  weight  of  the 
same  volume  of  water  at  the  same  temperature ;  he  thought  that  all  our 
specific  gravity  bottles  were  thus  made.  In  most  of  the  tables  of  the  specific 
gravity  of  acids  at  ]5°C.  the  base  of  comparison  was  water  at  its  greatest 
density,  4°C.,  and  these  could,  therefore,  not  agree  with  the  results  of  deter- 
minations made  with  the  instruments  in  common  use,  except  after  calcu- 
lation ;  the  Pharmacopoeia  should  at  least  have  exi^lained  this  difference. 
Mr.  Pile  stated  that  he  would  continue  the  examination  of  the  alcohol 
tables. 
Memoranda  giving  the  weight  of  one  fluidounce  of  various  tinctures  pre- 
pared according  to  the  old  and  new  Pharmacopoeias  were  handed  in  by 
Messrs.  Lowe,  Bobbins,  Wolff  and  the  Registrar  ;  they  were  referred  to 
Prof.  Maisch  at  whose  suggestion  the}  had  been  made. 
Mr.  Mclntyre  exhibited  a  specimen  of  chemical  food,  or  compound  si/rup 
of  pfhosphates^  made  with  phosphate  of  iron  of  the  Pharmacopoeia,  1880^ 
both  colored  and  plain. 
A  specimen  of  oU  of  luintergreen  was  exhibited.  It  is  well  known  that 
much  of  the  oil  of  wintergreen  of  commerce  is  made  from  the  sweet  birch 
twigs,  as  had  been  shown  by  Mr.  G.  W.  Kennedy,  of  Pottsville.  Reference 
was  also  made  to  the  statement  of  Mr.  Underhill  (see  "Anier.  Jour.  Phar.," 
1883,  p.  197)  that  the  actual  cost  of  collecting  gaultheria  leaves  was  greater 
than  the  oil  can  be  bought  for,  without  estimating  the  labor  or  fuel  value  of 
apparatus  used  in  preparing  it.  Specimens  of  colorless  and  of  artificial 
oil  of  wintergreen  exhibited  at  the  Centennial  Exhibition  in  1876  were 
also  commented  on. 
Prof.  Power  inquired  whether  it  had  yet  been  proven  that  the  oil  of  sweet 
birch  and  that  of  winter  green  were  identical  in  composition.  He  had  thought 
it  likely  that  they  might  be  compound  ethers  of  different  alcohols.  Prof. 
Mais-  h  said  that  Prof.  Piocter  had  probably  determined  that  in  1843,  in  his 
examination  of  sweet  birch  bark. 
There  being  no  further  business  the  meeting  adjourned.
