The  Alcohol  Solubility  of  Resin  of  Podophyllum. 
By  S.  Taylor. 
Freshly  prepared  podophyllum  resin  of  the  B.  P.  is  completely 
soluble  in  90  per  cent,  alcohol.  Mr.  Taylor  shows  that  the  resin 
in  part  gradually  becomes  insoluble;  thus  at  the  end  of  one  year 
the  soluble  sample  contained  0.7  per  cent,  insoluble  matter,  and 
at  the  end  of  the  second  year,  2.4  per  cent.  From  the  percentage 
of  insoluble  matter  it  may  be  possible  to  deduce  the  age  of  a  sample. 
Upon  the  invitation  of  Mr.  Maltby  Clague  it  was  decided  to  hold 
the  Conference  in  Newcastle-on-Tyne  next  year.  The  election  of 
officers  resulted  in  the  selection  of  Mr.  J.  E.  Tocher,  Ph.  C,  B.  Sc., 
F.  I.  C,  of  Peterhead,  for  president  for  the  coming  year  and  of  Mr. 
Maltby  for  local  secretary. 
FLUIDGLYCERATES* 
By  George  M.  Beringer. 
In  a  paper  presented  to  the  New  Jersey  Pharmaceutical  Associa- 
tion, at  the  meeting  of  last  year,  the  author  proposed  a  new  class  of 
liquid  galenicals  to  be  known  as  "  Fluidglycerates."  1  As  proposed 
these  are  to  be  of  a  uniform  drug  strength,  the  same  as  the  official 
fluidextracts,  1  c.c.  of  the  preparation  representing  1  Gm.  of  the 
drug.  The  title  "  fluidglycerate  "  was  selected  as  a  distinguishing 
term  to  designate  this  class  and  as  being  so  distinctive  that  it  would 
prevent  confusion  with  the  heterogeneous  glyceroles,  glycerins  and 
glycerites  already  introduced  and  some  of  which  are  official  under 
these  titles  in  the  various  pharmacopoeias. 
The  peculiar  solvent  and  sweetening  properties  of  glycerin  were 
early  recognized  and  numerous  attempts  have  been  made  to  utilize
