the  aqueous  solution  of  the  sugar  is  extracted  with  ether  in  order  to

In  a  recent  circular  of  a  North  Carolina  mining  company,  the 
claim  is  made  that  the  future  supply  of  some  of  the  rare  metals  will 
come  from  that  State. 
Monazite  yields  14  to  17  per  cent,  of  cerium  oxide,  the  metal  being 
worth  $2,880  a  pound  troy.  There  are  in  commerce  no  less  than 
twenty-two  preparations  of  cerium,  of  which  the  oxalate  and  nitrate 
are  the  most  important  medicinally. 
Gummite,  found  in  mica  deposits,  yields  50  per  cent,  uranium. 
The  fused  metal  is  worth  13^  cents  a  grain,  or  $768  a  pound. 
Lithrophitite  and  amblygonite  contain  from  9  to  10  per  cent,  lithium 
oxide.  The  demand  for  this  metal  has  largely  increased  of  late 
years,  owing  to  the  large  consumption  of  lithia  tablets. 
SURGICAL  ANTISEPTICS  AND  DRESSINGS. 
Antiseptic  Crayons.— L.  Adrian  (Nouveaux  Remedes,  13,  483)  has 
proposed  a  number  of  formulas  for  surgical  antiseptics.  The  fol- 
lowing is  a  typical  formula  for  an  antiseptic  crayon : 
Corrosive  sublimate  0*500  gramme 
Powdered  talc  25-000  " 
Gum  tragacanth   1.500  " 
Distilled  water  1  -  - 
For  10  crayons. 
In  place  of  the  corrosive  sublimate  a  number  of  medicinal  sub- 
stances may  be  used  as  antiseptics,  as  boric  acid,  iodoform,  phenol, 
salol,  iodol,  ichthyol,  etc.  Astringent  and  antiseptic  crayons  are 
prepared  by  using  tannin,  alum,  antipyrine,  ergotine  or  ferric  chlor- 
ide. Resolvent  crayons  are  made  with  potassium  iodide,  and  seda- 
tive crayons  with  belladonna,  morphine,  cocaine,  etc. 
Starch,  dextrin  or  sugar  may  be  employed  to  replace  part  of  the 
tragacanth.
