AmMay?i906arm'}      Notes  on  the  New  Pharmacopoeia.  211 
While  the  Pharmacopceia  contains  90  pages  more  than  that  of 
1890,  the  number  of  articles  which  are  now  official  is  less  by  34, 
151  having  been  dismissed,  and  117  new  ones  introduced. 
Among  those  dismissed  are  some  which  the  older  pharmacists 
will  regret,  if  only  for  association's  sake,  such  as  kermes  mineral, 
Plummer's  pill,  turpeth  mineral,  emplastrum-de-vigo  cum  mercurio, 
massa  copaibae,  potassa  cum  cake,  pulvis  antimonialis,  and  last,  but 
not  least,  to  some  of  you,  tobacco. 
Among  the  new  articles  inserted  in  addition  to  the  synthetics 
already  refered  to,  we  find  acetone,  trichloracetic  acid,  ethyl 
chloride,  hamamelis  water,  cresol,  liquor  cresolis  compositus  (resem- 
bling lysol),  solid  and  fluid  extract  of  scopola,  three  acetatracts  (that 
is  acetic  fluid  extract  of  lobelia,  sanguinaria,  and  squill) ;  guaiacol 
carbonate,  iodol,  kaolin,  antiseptic  solution  (resembling  listerine), 
liquor  sodii  phosphatis  compositus  (resembling  melachol),  methy- 
lene blue,  liquefied  phenol,  compound  acetanilid  powder  (a  migraine 
or  headache  powder),  saw  palmetto  (under  the  name  of  sabal), 
scopolamine  hydrobromide,  strophanthin,  and  vanillin. 
A  few  of  the  more  noticeable  changes  in  name  are  the  follow- 
ing :— 
Arsenous  acid  is  now  more  correctly  called  arsenic  trioxide  ; 
chromic  acid,  chromium  trioxide  ;  carbolic  acid  is  now  known  as 
phenol.  Haloid  salts  of  the  alkaloids  are  now  called  hydrochlor- 
ides instead  of  hydrochlorates ;  hydrobromides  instead  of  hydro- 
bromates,  etc.  Ferri  oxidum  hydratum  is  now  ferri  hydroxidum, 
and  the  same  nomenclature  applies  to  the  other  hydroxides  (sodium, 
potassium,  etc.),  resin  plaster  is  now  adhesive  plaster,  liquor  potas- 
sse  and  sodse  are  now  liquor  potassii  and  sodii  hydroxidi.  Resorcin 
is  now  resorcinol.  Salol  is  given  its  full  chemical  name,  phenyl- 
salicylate.  Sodium  hyposulphite  is  now  thiosulphate.  Sodium 
sulphocarbolate  is  now  denominated  as  sodium  phenolsulphonate. 
Chlorine  water  is  no  longer  recognized  as  aqua  chlori  but  as  liquor 
chlori  compositus.  The  preparation  differs,  however,  from  the 
chlorine  water  of  1890,  being  made  from  potassium  chlorate,  hydro- 
chloric acid  and  water  by  the  usual  method  of  preparing  chlorine 
water  extemporaneously.  It  contains  various  compounds  of  potas- 
sium and  chlorine  as  well  as  the  free  gas.  Catechu  is  no  longer 
found  in  the  Pharmacopoeia,  its  place  being  taken  by  gambir  (terra 
japonica).    I  am  at  a  loss  to  understand  the  reasons  for  this  change,
