I  September,  1907. 
Cucumis  Trigonus. — Messrs.  Nay  lor  and  Chappel  find  that  the  pulp 
and  rind  of  the  fruit  contain  a  body  that  is  closely  allied  to,  if  not 
identical  with,  colocynthin. 
Bacteriology  of  Plasters  and  Protective  Tissues. — Mr.  G.  Pinchbeck 
has  found  that  plasters  with  a  water-soluble  basis  are  very  unsatis- 
factory from  an  aseptic  point  of  view.  He  suggests  the  use  of  a 
rubber  basis  and  gives  formulae. 
Officinal  Testing. — Mr.  J.  P.  Gilmour  records  his  experience  with 
chemical  tests  and  demonstrates  the  need  for  systematic  testing,  by 
pharmacists,  of  articles  taken  into  stock. 
Pungent  Principles  of  Ginger. — Messrs.  Garnett  and  Grier  have 
isolated  from  the  phenolic  constituents  of  ginger,  an  oil  which  they 
believe  to  be  chiefly  unchanged  gingerol. 
Antimonium  Sulphuratum. — Messrs.  Howard  and  Harrison  criti- 
cise the  B.  P.  tests  for  this  substance  and  suggest  important  modifi- 
cations. 
Resinoids. — Mr.  D.  B.  Dott  discusses  the  need  for  adding 
extraneous  matter  to  preparations  of  this  kind  to  overcome  their 
hygroscopic  properties. 
Brucea  Antidys  enteric  a  and  Brucea  Sumatrana. — Drs.  F.  B.  Power 
and  A.  H.  Salway  have  examined  the  fruits  of  the  former  and  find 
that  the  constituents  are  similar  to  those  contained  in  the  fruit  of  B. 
Sumatrana. 
An  examination  of  the  bark  of  both  plants  demonstrated  but  a 
comparatively  small  proportion  of  the  bitter  principles. 
A  New  Method  for  Preparing  Saccharated  Carbonate  of  Iron. — 
Mr.  J.  H.  Franklin  suggests  a  modified  formula  for  this  preparation. 
Determination  of  Ferrous  Carbonate. — Mr.  Philip  H.  Crewe  sug- 
gested several  modifications  in  the  B.  P.  assay  of  saccharated 
carbonate  of  iron. 
What  is  Oil  of  Juniper? — Messrs.  Umney  and  Bennett  point  out 
that  the  oil  from  the  partially  dried  berries  and  the  oil  from  the 
fresh  berries  differ  materially. 
Note  on  Oil  of  Juniper. — Mr.  F.  C.  J.  Bird  records  his  experi- 
ments with  oil  of  juniper  and  suggests  that  the  present  B.  P. 
description  of  this  oil  be  made  more  definite. 
Mr.  Robert  Wright,  F.C.S.,  was  elected  president  of  the  British 
Pharmaceutical  Conference  for  the  coming  year,  and  Aberdeen  was 
selected  as  the  place  of  meeting  for  1908.
