Emulsion  of  lanolin. — As  this  emulsion  is  not  easy  to  prepare 
Hoefle's  method,  given  in  Ztsehr.  d.  Ost.  Ap.  Ver.,  is  worthy  of  notice: 
Lanolin  is  heated  to  completely  expel  the  water  it  contains ;  it  is  then 
weighed  and  rubbed  up  with  half  its  weight  of  powdered  gum  arable, 
the  quantity  of  water  required  for  oil  emulsions  added,  and  the  emul- 
sion prepared  in  the  usual  manner. — Pharm.  Ztsehr.  f.  Russland, 
1887,  p.  510. 
Antiseptic  petrolatum. — Brondel,  in  3Ied.  Ztg.,  recommends  for  use 
on  the  hands  of  accoucheurs  a  mixture  composed  of  corrosive  subli- 
mate and  oil  of  eucalyptus,  each,  10  parts;  soft  paraffin,  100  parts. — 
Rundschau,  Frag,  1887,  p.  752. 
Binoxide  of  hydrogen  as  a  styptic. — According  to  Xeudorfer,  3Ied. 
Zeitung,  1887,  15,  a  single  drop  pressed  upon  the  wound  for  one  min- 
ute is  sufficient  to  stop  the  bleeding. — Archiv  der  Pharmacie,  1887, 
p.  588. 
Canadol  is  recommended  as  a  reliable  and  economical  anaesthetic  to 
take  the  place  of  ether  and  cocaine.  It  is  a  colorless,  very  volatile  and 
inflammable  liquid,  obtained  as  a  by-product  in  the  distillation  of 
American  petroleum  ;  in  odor  resembles  benzin,  and  is  not  miscible 
with  water  or  alcohol  in  any  proportion.  During  its  use  the  skin 
becomes  very  hard  and  completely  insensible.  Operations  ai'e  easily 
conducted,  and  in  cases  of  bleeding  the  blood  may  be  chilled  at  once. — 
Rundschau,  Prag,  1887,  p.  729.  (See  America^^  Jourxal  of 
Pharmact,  1887,  p.  490). 
To  prevent  bumping  in  retorts  during  distillation. — Reissmann,  in 
Ph.  Centralh.  recommends  the  use  of  a  tightly  wound  spiral  of  plati- 
num wire,  loosely  filled  with  long  pieces  of  pumice-stone,  the  ends  of 
the  spiral  so  turned  in  that  the  pieces  of  pumice-stone  can  freely  move 
about  without  falling  out.  The  weight  of  the  spiral  must  be  heavy 
enough  to  sink  in  the  liquid.  For  very  large  retorts  several  of  these 
spirals  must  be  used. — Rundschau,  Prag,  1887,  p.  818. 
Improved  insect  powder. — A  mixture  of  1  part  naphthalin,  and  100 
parts  powdered  pyrethrum  roseum  is  more  effectual  than  the  pyreth- 
rum  flowers  alone.  The  naphthalin  must  be  in  very  fine  powder  —
