the  plan  proposed  by  him,*  to  use  in  all  formulas  only  the  term3  parts  and 
measures,  was  the  simpler  one,  equally  applicable  to  the  weights  and  measures 
now  in  use  and  to  the  metrical  system,  so  that  no  further  change  would  be 
necessary.  Mr.  Williams  adopted  the  same  views.  Mr.  Wood  replied  at  con- 
siderable length,  after  which  Mr.  Edward  Hested  read  a  paper  on  the  occur- 
rence of  copper  in  cajeput  oil ;  six  samples  examined  by  him  contained  copper : 
by  redistillation  a  colorless  oil  was  obtained,  which,  in  contact  with  copper, 
dissolved  that  metal  and  turned  green. 
Pharmaceutical  Society  of  Paris. — At  the  session  held  Dec.  6th,  1871, 
Mr.  Lefort  in  the  chair,  Mr.  Grassi  was  elected  Yice-President  and  Mr.  Bour- 
goin  Annual  Secretary  for  1872.  An  interesting  discussion  took  place  on  the 
Norwegian  pot  for  cooking  victuals  at  a  temperature  below  100°  0.  Mr.  Bau- 
drimont  communicated  an  analysis  made  of  an  East  Indian  cinchona  bark 
[Cinch,  succzrubra),  which  yielded  37^  per  cent,  of  extract  and  5'45  per  ct.  of 
sulphates  of  the  alkaloids,  one  per  cent,  being  the  quinia  salt,  the  remainder 
quinidia  and  cinchonia  sulphate.  Mr.  Marais  ascribed  the  large  yield  of  extract 
to  the  bark  being  young.  Mr.  Planchon  presented  to  the  Society  wax  from 
Geroxylon  andicola,  of  New  Grenada,  and  a  root  of  Psychotria  emetica,  and 
made  some  remarks  about  different  ipecacuanhas.  Mr.  Mehu  read  a  paper  on 
the  preparation  of  indigotin.f  Mr.  Soubeiran  exhibited  compressed  and 
desiccated  bread  prepared  by  Mouries.  The  same  gentleman  referred  to  the 
loss  of  the  Chicago  College  of  Pharmacy,  sustained  by  the  great  fire,  and  asked 
for  contributions  towards  reforming  its  collections.  Mr.  Guichard  read  a  paper 
on  soluble  oxide  of  iron,  which  is  obtained  by  precipitating  in  the  presence  of 
sugar,  sequichloride  of  iron  with  an  excess  of  caustic  soda,  the  soluble  com- 
pound containing  soda,  ferric  oxide  and  sugar;  glycerin  and  mannite  yield 
similar  compounds. 
At  the  meeting  of  January  8th,  Mr.  Stan.  Martin  presiding,  Mr.  Baudrimont 
spoke  about  his  researches  on  sulpho-chloroform.  The  reaction  between  chlo- 
roform and  sulphide  of  sodium  is  complicated  and  does  not  yield  any  satisfactory 
results.  On  acting  with  the  same  sulphide  upon  a  cold  aqueous  or  alcoholic 
solution  of  chloral,  the  liquid  becomes  hot  and  of  a  beautiful  red  color.  The 
aqueous  solution  soon  becomes  turbid,  and  deposits  an  abundant  yellow  preci- 
pitate. Similar  results  are  obtained  with  an  alcoholic  solution,  which,  however, 
assumes  such  an  intense  coloration  that  by  this  reaction  chloral  may  be  detected 
in  a  liquid  containing  only  ^o*  '^is  compound  stains  the  hands  and  paper, 
and  the  coloration  is  pretty  persistent,  although  it  changes  even  in  the  dark. 
The  February  session  was  held  on  the  7th,  Mr.  Martin  in  the  chair.  Mr. 
Bussy  read  a  note  by  Mr.  Carles  on  the  efflorescence  upon  vanilla,  to  which  he 
ascribes  acid  properties  and  the  formula  Cie  Hs  Oi  ;J  the  iodine  substitution 
compounds  crystallize  well.
