poeias  named  gave  the  following  wide  variation  in  results :  Japanese 
Pharmacopoeia,  1.78  per  cent. ;  Belgian,  1.71  per  cent. :  United  States, 
1.67  per  cent.;  Swiss,  1.735  Per  cent.;  Swedish,  1.735  Per  cent.; 
Austrian,  2.15  per  cent.;  Hungarian,  2.13  per  cent.;  Dutch,  2.06  per 
cent;  German,  1.54  per  cent.;  Italian,  2.03  per  cent.  These  results 
point  to  the  desirability  of  an  international  process  and  standard. —

Leukozon. — Calcium  perborate  mixed  with  talc  and  standardized 
to  a  content  of  5  per  cent,  of  available  oxygen.  Used  as  an  antiseptic 
dusting  powder. — Chem.  and  Drug.,  1914,  vol.  84,  p.  443. 
Liquid  Paraffin. — Peck,  J.  Wicliffe,  in  discussing  the  production 
and  use  of  liquid  paraffin^  says :  "  It  has  been  stated  that  liquid  paraffin 
should  not  be  given  with  meals  or  during  the  process  of  digestion, 
as  it  prevents  the  pancreatic  emulsiflcation  of  fats.  The  experiments 
in  vitro  I  do  not  think  would  be  repeated  in  the  body.  From  prac- 
tical experience,  just  after  a  meal  is  the  time  I  should  suggest.  If 
taken  on  an  empty  stomach  the  oil  passes  through  very  often  un- 
mixed with  the  stools  and  taking  the  usual  thirty  hours.  When 
given  in  excess  to  animals  it  passes  through  with  apparently  no 
colorable  fats  dissolved." — Pharm.  J.,  19 14,  vol.  92,  p.  509. 
Novotryposafrol. — A  derivative  of  tryposafrol,  for  use  in  try- 
panosome  infections  and  also  in  veterinary  medicine. — Chem.  and 
Drug.,  1914,  vol.  84,  p.  443. 
Perydal. — An  antiseptic  dusting  powder,  containing  formalde- 
hyde and  Peruvian  balsam.  It  is  used  as  a  general  antiseptic  for 
wounds,  for  dusting  in  the  stockings,  and  for  infants. — Pharm.  J., 
1914,  vol.  92,  p.  286. 
Phenolphthalein.  (Editorial.) — A  recent  report  of  the  labora- 
tories of  bacteriology  and  physiologic  chemistry  at  the  Jefferson 
Medical  College  in  Philadelphia  states  that  in  twenty  experiments, 
in  each  of  which,  before  beginning  the  trials,  the  subject's  urine 
showed  no  trace  of  albumin  by  delicate  tests,  24-hour-specimen,  col- 
lected after  the  administration  of  phenolphthalein  in  a  from  i-grain 
to  2-grain  dose,  gave  positive  tests  for  protein  in  every  case.  *The 
amount  of  albumin  varied  from  a  trace  up  to  0.25  per  cent,  by 
Esbach's  quantitative  method.  The  precipitate  in  many  of  the  cases 
was  tested  and  found  to  be  insoluble  in  alcohol.  Traces  of  phenol- 
phthalein were  demonstrated  in  the  urine.  The  albuminuria  lasted 
from  one  to  three  days. — /.  Am.  M.  Assoc.,  1914,  vol.  62,  p.  1560. 
Phenolphthalein-agar  is  agar-agar  impregnated  with  phenolph-
