$45.  There  was  exhibited  a  specimen  of  sugar  wliieli  was  largely  adul- 
terated with  grape-sugar,  and  sold  at  a  cent  a  pound  less  than  pure  sugar. 
The  difi'erences  under  the  microscope  w^ere  very  marked  ;  the  sugar  was 
manufactured  in  New  York. 
Prof.  F.  B.  Power  read  a  short  paper  upon  the  analysis  of  a  mineral  sup- 
posed to  contain  molybdenum,  and  sent  to  this  city  for  a  market.  It  was^ 
however,  found  not  to  contain  this  metal  (see  page  8). 
Prof.  Remington  called  attention  to  samples  of  some  volatile  oils  which 
are  now  being  placed  upon  the  market  under  the  name  of  qtci.ntessential 
oils,  represented  to  be  much  stronger  than  the  ordinary  oils  of  the  same 
name.  Prof.  Power  stated  that  the  experience  of  one  large  manufacturer 
in  Europe  was,  that  the  residue  of  a  resinous  character  in  redistillation  of 
some  volatile  oils  was  from  5  to  10  per  cent.  ;  and  it  is  well  known  that  but 
few  volatile  oils  exactly  represent  the  true  and  entire  odor  of  the  plants^ 
from  M'hence  they  are  derived. 
A  sample  of  uncured  vanilla  bean  was  exhibited  by  Prof.  Remington. 
When  first  obtained  this  was  of  quite  light  brown  color,  and  its  odor  was 
much  less  marked  than  it  is  at  present,  although  it  is  still  deficient  in  this 
latter  respect  to  the  best  quality  of  merchantable  beans. 
Prof.  Remington  called  attention  to  a  new  class  of  preparations  called 
Diali/sates,  made  by  Messrs.  Mclntyre  &  Embury  of  New  York.  The 
drugs  are  exhausted,  submitted  to  dialysis,  and  the  fluid  solutions  of  their 
active  j^rinciples  are  reduced  to  definite  strengths. 
Allusion  w^as  made  to  the  ferruginous  2^(11  of  £  I  and  in  the  meeting  last 
month,  and  it  was  suggested  that  carbonate  of  magnesium  might  be  used 
more  advantageously  than  carbonate  of  potassium,  as  there  would  be  less 
difficulty  in  preventing  the  ferrous  sulphate  being  converted  into 
carbonate. 
Prof.  Maisch,  on  behalf  of  Mr.  Hugo  Oppermann,  jn-esented  thirteen 
packages  of  botanical  speeiniens,  inostly  of  plants  from  the  Southern  and 
Western  States,  for  the  Herbarium  of  the  College.  On  motion,  the 
thanks  of  the  College  were  voted  to  Mr.  Oppermann  for  the  donation. 
Tiiere  being  no  further  business,  on  motion  the  meeting  adjourned.
