more  or  less  impractical.  The  experience  is  particularly  interesting, 
in  view  of  the  expressed  willingness  of  the  General  Medical  Council 
to  make  the  metric  system  the  only  system  of  weights  and  measures 
official  in  the  coming  edition  of  the  British  Pharmacopoeia." 
Acetanilid  is  reported  in  several  of  the  German  pharmaceutical 
journals  as  being  at  times  contaminated  with  acet-toluidin,  and  it  is 
recommended  to  test  doubtful  samples  of  this  possible  admixture. 
Antiseptic  Paper. — A  recent  German  patent  covers  the  addition  of 
various  antiseptics  to  paper  pulp  before  the  same  is  passed  through 
the  machine.  The  proposed  uses  are  for  wrapping,  or  protecting, 
readily  decomposed  articles  or  food  stuffs.  The  antiseptics  that 
have  been  used  in  this  way  are  boric  acid,  salicylic  acid  and  thymol.

Cellotropin-mono-benzoyl-arbutin  is  recommended  as  a  remedy  in 
tuberculosis  and  scrofula.  Cellotropin  is  prepared  by  the  interac- 
tion of  arbutin  and  benzoyl  chloride,  and  forms  a  tasteless  and  odor- 
less powder,  insoluble  in  most  organic  solvents  and  only  slightly 
soluble  in  water  and  in  alcohol.  Under  the  influence  of  hydrolytic 
agents  it  is  decomposed  into  benzoic  acid,  hydroquinone  and  glu- 
cose.  {Phar.  Jour.,  June  23,  1904,  page  1001.) 
Cod-liver  Oil. — A  market  report  in  the  Pharmaceutical  Journal, 
(June  11,  1904,  page  818)  notes  that  the  production  of  cod-liver  oil 
in  Norway  during  the  past  season  amounts  to  an  aggregate  of 
12,770  barrels,  as  against  2,300  barrels  in  1903.  While  the  figures 
for  1904  show  a  decided  increase  over  the  abnormally  low  yield  in 
1903,  they  are  still  far  below  the  aggregate  of  previous  years.  The 
amount  produced  in  1901,  for  instance,  being  28,210  barrels. 
Gallogen. — This  is  a  trade  name  for  ellagic  acid.  It  is  obtained 
by  heating  a  mixture  of  gallic  acid  and  iodine.  It  may  also  be  ob- 
tained by  extracting  the  pods  of  divi-divi  with  alcohol,  and  precipi- 
tating the  alcoholic  extract  with  water.  The  precipitate  contains 
ellagic.gallic  acid  that  on  heating  to  1  io°  C.  is  converted  into  ellagic 
acid. 
Gallogen  is  an  odorless,  yellowish,  crystalline  powder,  insoluble  in 
neutral  or  in  acid  liquids,  but  readily  soluble  in  alkaline  liquids.  It 
is  almost  insoluble  in  ether,  and  is  only  slightly  soluble  in  alcohol. 
Gallogen  has  been  suggested  as  an  active  and  reliable  intestinal 
astringent,  and  is  to  be  given  in  doses  of  from  -30  to  -6o  four  to  six 
times  a  day  (Apoth.  Zeitg.,  1904,  page  178).
