form.  After  separation  wash  the  alkaline  solution  with  3 
c.  cm.  of  chloroform,  mix  the  chloroform  solutions,  evaporate 
in  a  dish  of  known  weight  and  dry  the  residue,  which  should 
be  nearly  colorless,  at  a  temperature  of  2000  F.  (93 0  C).  The 
weight  of  the  residue  thus  obtained  multiplied  by  50  will 
give  the  percentage  of  alkaloid  present  in  the  extract.  Hav- 
ing thus  ascertained  the  strength,  warm  the  extract  over  a 
water-bath  in  a  dish  of  known  weight  and  adjust  by  evapora- 
tion or  by  the  addition  of  distilled  water  and  sugar  of  milk 
in  such  proportion  that  the  finished  extract  shall  be  of  firm  con- 
sistence and  shall  contain  2  per  cent,  of  alkaloid.

It  is  proposed  to  be  prepared  with  alcohol  of  the  same

The  fourth  paper,  entitled  "  Observations  on  the  .Thera- 
peutic Action  of  Scopola  carniolica,"  by  Sir  Dyce  Duckworth, 
M.D.,  relates  the  action  of  the  drug  in  seven  cases,  and  con- 
cludes as  follows : 
So  far  as  these  few  observations  go,  I  think  it  justifiable 
to  affirm  that  in  scopola  we  have  a  drug  which  proves  itself 
equally  effectual  with  belladonna,  and  if  it  can  be  supplied  at 
a  cheaper  rate  than  the  latter  drug,  it  can  hardly  fail  to  prove 
a  boon  to  a  large  class  of  sufferers  who  can  ill-afford  to  pay 
for  efficient  local  employment  of  belladonna.  I  could  have 
wished  to  adduce  many  more  facts  before  this  meeting,  but
