Mix  the  powders,  moisten  the  mixture  with  three  fluidounces 
of  the  diluted  alcohol  mixed  with  the  glycerin,  and  pack  in  a 
conical  percolator.  Then  pour  on  diluted  alcohol  until  a  pint  of 
tincture  has  passed.  Evaporate  on  a  water  bath  to  a  soft  extract 
and  preserve  it  for  use. 
This  extract  has  been  used  for  thirty  years  as  an  application  to 
painful  decaying  teeth  where  the  nerve  pulp  is  sufficiently  acces- 
sible to  bring  the  extract  into  contact  with  it.  The  glycerin  has 
been  added  more  recently  to  prevent  the  extract  from  becoming 
friable.  A  solution  in  which  these  quantities  are  present  in  a  pint, 
odorized  with  oil  of  gaultheria,  makes  a  good  liquid  preparation, 
applied  on  cotton.  The  soft  extract  is  applied  by  inserting  a 
pellet  in  the  cavity  and  then  a  wad  of  cotton,  advising  the 
patient  to  reject  the  saliva  which  freely  flows  from  the  action  of 
the  pyrethrum  on  the  salivary  glands.
