upon  a  slow  fire,  and  the  affected  part  immersed  until  the  liquid  be- 
comes too  hot ;  the  part  is  then  allowed  to  dry  near  the  fire.  The 
application  is  made  once  daily,  a  complete  cure  being  effected  after 
four  or  five  days. —  Wittsteins  Viertelj.  Sehrift.,  1873,  602. 
PILLS  OF  SULPHATE  OF  QUINIA. 
By  William  Delker. 
Pharmacists  are  often  requested  by  physicians  to  make  quinia  pills 
as  small  as  they  possibly  can,  and,  after  trying  a  number  of  experi- 
ments, I  have  found  that  glycerin  is  the  best  excipient.  It  makes  a 
very  good  mass,  and  does  not  increase  the  bulk  of  the  pills.  I  have 
been  using  it  for  a  number  of  years,  and  it  has  always  given  general 
satisfaction.    The  following  is  the  proportion  of  glycerin  to  be  used  : 
1^.    Quiniae  Sulph.,  .  .  .    grs.  xxiv, 
Glycerinae,  ....         gtt.  viii. 
M.  ft.  pil.  no.  xii. 
I  drop  the  glycerin  from  a  one-ounce  prescription  vial. 
Note  by  the  Editor. — Glycerin  has  been  suggested  as  an  ex- 
cipient for  quinia  pills  by  Dr.  T.  E.  Jenkins,  in  "  Amer.  Journal  of 
Pharmacy,"  1869,  p.  119;  and  mixed  with  honey,  by  W.  P.  Creecy,

ON  A  NEW  ALLOTROPIC  MODIFICATION  OF  PHOSPHORUS. 
By  Prof.  Edwin  J.  Houston. 
In  connection  with  Prof.  Elihu  Thompson,  of  the  Artisans'  Night 
School,  the  author  has  undertaken  an  extensive  series  of  experiments, 
resulting,  it  is  believed,  in  the  discovery  of  a  new  allotropic  modifica- 
tion of  phosphorus. 
It  has  long  been  known  that  when  phosphorus  is  boiled  in  strong 
potassium  hydrate,  and  then  allowed  to  cool  slowly,  it  retains  its 
liquid  state  for  some  little  time,  but  that  if  shaken,  or  touched  by  a 
sharp  point,  instantly  solidifies. 
We  believe  that  in  the  cases  heretofore  observed,  the  property  of 
retaining  the  liquid  state  may  be  owing  to  the  admixture  with  the 
ordinary  phosphorus  of  an  allotropic  modification,  having  the  proper-
