Note  on  Extract  of  Malt  with  Cod  Liver  Oil,  and  The  Keeping  Qualities  of 
Certain  Samples  of  Spirit  of  Nitrous  Ether,  were  two  papers  by  Henry  Wil- 
liam Jones. 
With  a  view  to  rendering  the  natural  features  of  the  district  more  intelligible 
to  visitors,  G.  C.  Druce  next  gave  some  brief  descriptive  Notes  on  the  Geology, 
Botany  and  River  Systems  of  Oxford  and  its  Neighborhood.  An  instructive 
paper  was  then  read  on  Animal  Extracts,  by  C.  E.  Stuart.  An  Exaviination 
of  Leonurus  Cardiaca,  was  the  subject  of  a  paper  by  W.  A.  H.  Nay  lor.  The 
drug  for  this  analysis  was  grown  and  supplied  by  E.  M.  Holmes,  who  at  the 
same  time  supplied  some  interesting  information  concerning  it. 
S.  Rideal  contributed  a  paper  on  The  Conditions  of  Papain  Digestion.  Com- 
pared with  pepsin  under  identical  conditions,  papain  seemed  to  give  the  better 
results  with  meat  fibrin,  but  with  regard  to  egg  albumen  its  digestive  power 
appeared  intermediate  between  that  of  two  pepsins  examined. 
C.  J.  S.  Thompson  recommended  the  use  of  Cocoanut  Stearin  as  a  Basis  for 
Suppositories.  When  mixed  with  white  wax  in  the  proportion  of  four  ounces 
of  the  stearin  to  340  grains  of  the  wax,  the  author  had  found  that  it  furnished 
a  mass  melting  at  980  F.,  and  becoming  solid  at  640  F.  Its  advantages  over  theo- 
broma  butter  appear  to  be  in  its  keeping'qualities,  and  in  its  solidifying  more 
rapidly. 
R.  H.  Parker  read  a  Note  on  Phosphorus  Pills.  The  quantity  of  phosphorus 
necessary  for  24  pills  is  dissolved  in  30  minims  of  carbon  disulphide,  and  the 
solution  poured  on  24  grains  of  liquorice  powder  in  a  mortar,  and  stirred  with  a 
spatula  until  the  solvent  is  nearly  dissipated,  when  sufficient  syrup,  glycerin 
and  tragacanth  powder  are  added  to  form  a  pill  mass.  The  Nomenclature  of 
Official  Remedies  was  the  subject  of  a  paper  by  Joseph  lace. 
Richard  Usher  read  a  paper  on  English  Medici?ial  Rhubarb  and.  Henbane,  in 
which  the  methods  of  cultivating  these  drugs  in  England  were  discussed  and 
explained.  Tinctura  Ergotce  Ammoniata  was  treated  in  a  paper  by  J.  T. 
Hornblower.  A  communication  on  Rhubarb  was  presented  by  Barnard  S. 
Proctor.  He  had  been  investigating  this  drug  at  intervals  since  1868.  The 
odorous  principle  of  the  root  he  found  was  capable  of  being  extracted  by  perco- 
lation with  chloroform,  without  detracting  from  the  medicinal  value  of  the 
powder ;  but  it  was  found  that  the  deodorized  powder  acquired  smell  again, 
apparently  by  the  action  of  air  and  moisture.  When  chrysophanic  acid  has 
been  removed  from  the  powder  by  percolation  with  benzol,  a  further  develop- 
ment of  the  acid  takes  place  on  submitting  the  exhausted  powder  to  the  action 
of  air,  water  and  potassium  hydrate. 
The  Adaptation  of  the  Soap  Basis  of  Linimentum  Potassii  Iodidicum  Sapone 
to  some  other  Br.  P.  Liniments,  was  suggested  in  a  communication  by  E.  W. 
Lucas.  J.  F.  Liverseege  presented  papers  on  Tincture  of  Lodine  and  its 
Analysis,  and  The  Calibration  of  Pipettes. 
Some  Fallacies  in  the  Testing  of  Essence  of  Lemon  were  explained  by  Arthur 
A.  Barrett,  of  Messina.  Finally  a  paper  was  presented  from  David  Hooper  on 
Extract  of  Indian  Hemp.  The  author  gave  a  brief  review  of  the  history  of  the 
plant,  and  called  attention  particularly  to  the  extract  as  containing  the  active 
principle  of  the  drug.
