and  the  latter  sajDonified  in  the  cold  with  12*5  kilos  soda  lye  of  38°B.

Camphorated  Sulphur  Soap. — Cocoanut  oil,  12  kilos;  soda  lye  of 
38 ^B.,  6  kilos;  sulphuretted  potash,  1  kilo  dissolved  in  water  0*5  kilo; 
camphor,  160  grams,  to  be  dissolved  in  the  melted  cocoanut  oil. 
Infant  Powder. — Dr.  Klamann  recommends  as  preferable  to  lyco- 
23odium,  starch,  etc.,  the  following  mixture  for  dusting  in  intertrigo, 
eczema  and  erythema  of  infants:  Calcined  magnesia  5*0,  talc  25*0, 
salicylic  acid  0*2,  oleo-balsamic  mixture  gtt.  x.  The  powder  is  a  very 
effectual  remedy  and  entirely  harmless. — Phar.  Centralhalle,  Dec.  15,

Phosphorescent  Powders,  which  have  been  recently  employed  in 
Europe  for  rendering  signs,  dials,  etc.,  visible  at  night,  are  prepared 
by  Pfeiffer,  Fitz,  Corty  and  Talleyrand  Perigoid,  by  mixing  100  grams 
of  calcium  carbonate  and  phosphate,  prepared  by  calcining  oyster  shells 
or  cuttlefish  bones,  with  100  grams  caustic  lime,  25  grams  calcined 
table  salt,  and  adding  to  this  mixture  from  20  to  25  per  cent,  of  sul- 
phur and  3  to  7  per  cent,  of  sulphide  of  calcium,  barium,  strontium 
or  magnesium,  previously  exposed  to  the  sunlight.  A  phosphorescent 
material  prepared  by  incinerating  marine  algpe  is  also  added  for  the 
purpose  of  increasing  the  illuminating  power.  The  powders  are  ren- 
dered adhesive  by  means  of  varnish,  collodion,  paraffin,  isinglass,  etc., 
or  may  be  incorporated  in  melted  glass. — Jour,  de  Phar.  et  de  Chim.,

Extract  of  Vanilla. — So  many  formulas  have  been  published  hj 
which  this  extract  or  tincture  can  be  made,  that  it  seems  almost  super- 
fluous to  offer  another,  yet,  having  tried  many  of  them,  I  found  none 
so  satisfactory  as  the  following  : 
R    Vanilla  bean,  of  good  (juallty,  .  .    1  oynce 
Rock  candy,         ...  2  ounces 
Alcohol,        .  .  .  .9  fluidounces 
Water,    .  .  .  .  7  " 
Cut  the  vanilla  as  small  as  possible  Avith  a  sharp  knife,  then  transfer 
it  to  an  iron  mortar  and  beat  it  and  the  rock  candy  into  powder,  which 
is  to  be  put  into  a  bottle  with  the  alcohol  and  allowed  to  macerate
