to  about  three  fluidounces ;  triturate  this  with — 
Extract  of  Belladonna,  one  ounce. 
Then  take  of — 
Camphor,  in  powder,  six  drachms  and  a  half ; 
Resin  cerate,  six  ounces  and  a  half. 
Mix  these  by  fusion  at  a  moderate  heat  and  incorporate  them 
with  the  mixed  extracts  of  tobacco  and  belladonna.* 
The  following  formula  is  that  formerly  much  in  use  by  Prof. 
Samuel  Jackson,  under  the  name  of 
Dissolving  Salve  for  Breasts.

Mix  together  the  cerate  and  tannin  ;  dissolve  the  soap  in  a  lit- 
tle water,  by  a  gentle  heat,  add  to  this  the  extract  previously 
rubbed  down  with  a  little  water  ;  then  mix  rapidly  on  a  warm 
slab  the  two  parts  together. 
Of  the  applications  I  have  had  occasion  to  dispense  during 
several  years  past,  that  prescribed  by  Dr.  Ellwood  Wilson,  con- 
sisting of  equal  parts  of  Logan's  plaster  and  the  officinal  Bel- 
ladonna plaster,  seems  the  best  adapted  to  rank  as  a  standard 
remedy  in  mammary  abscess,  and  I  have  made  it  the  basis  of  a 
plaster  which  I  have  supplied  to  physicians  for  the  requirements 
of  country  practice. 
The  proper  shape  of  mammary  abscess  plasters  for  general 
use  is  a  subject  requiring  some  thought,  and  I  have,  I  think, 
made  an  improvement,  in  explaining  which  the  accompanying  cut, 
from  the  new  edition  of  my  work,  will  aid.  Such  plasters  are 
usually  made  round,  varying  from  seven  to  eight  and  a  half 
inches  in  diameter,  with  a  hole  in  the  middle  for  the  nipple,  they 
then  require  to  be  incised  at  least  half  way  in  from  the  outer 
edge,  so  as  by  lapping  the  edges  to  accommodate  it  to  the  convex 
shape  of  the  breast,  a  method  which  causes  such  inequalities
