sisted  of  an  interesting  and  readily  followed  review  of  the  uses  of 
physical  forces,  particularly  electricity,  in  chemistry  and  attention 
was  more  particularly  directed  to  the  electrolysis  of  organic  com- 
pounds. Following  the  address  by  the  chairman  the  Committee  on 
Ebert  Prize,  through  its  chairman,  Prof.  W.  A.  Puckner,  announced 
that  the  prize  had  been  awarded  to  J.  O.  Schlotterbeck  for  his  "  Con- 
tribution on  the  Chemistry  of  Bocconia  Cordata." 
The  report  of  the  committee  on  Drug  Market  was  presented,  in 
abstract,  by  Lyman  F.  Kebler. 
The  consideration  of  original  contributions  was  then  proceeded 
with  as  follows: — 
Otto  of  Rose. 
By  John  Uri  Lloyd. 
Professor  Lloyd  presented  several  authentic  samples  of  otto  of 
rose,  and  also  described  how  he  was  able  to  secure  the  specimen  of 
otto  of  white  rose  and  otto  of  red  rose  directly  from  the  still. 
Chemical  Examination  of  Eriodictyon. 
By  F.  B.  Power  and  Frank  Jutim. 
This  paper  was  presented  in  abstract  by  Prof.  Charles  Caspari,  Jr. 
It  consists  of  a  review  of  the  literature  and  records  of  previous 
examinations  and  also  recounts  in  detail  the  results  of  the  present 
examination. 
The  Botanical  Characters  of  some  California  Species  of 
Grindelia. 
By  P.  E.  F.  Perredes. 
This  paper  was  also  presented  in  abstract  by  Professor  Caspari. 
It  contains  the  account  of  an  extensive  investigation  of  the  grinde- 
lias  of  commerce.    The  most  widely  used  and  most  frequently  met 
with  species,  at  the  present  time,  is  Grindelia  Camporum. 
Separation  of  Morphine  from  Glycerin. 
By  H.  M.  Gordin.    In  collaboration  with  W.  H.  Harrison. 
From  a  solution  of  a  morphine  salt  in  glycerin  the  alkaloid  is  not 
precipitated  by  alkaline  carbonates.  The  glycerin  cannot  be  driven 
off  by  steam  at  temperatures  that  would  not  injure  the  morphine. 
Removal  of  glycerin  by  converting  it  into  a  lead  compound  by 
means  of  PbO  and  subsequent  treatment  with  hot  amyl  alcohol 
gave  negative  results.    Owing  to  the  solubility  of  glycerin  in  amyl
