a  few  weeks  it  became  evident  the  sore  was  enlarging  and  getting 
worse.  The  powder  was  applied  for  about  a  month,  a  large  eschar 
separated,  healing  was  induced  by  emollient  applications,  the  cure  was 
complete  and  he  remains  well  to  this  day,  although  fully  five  years 
have  elapsed.  I  could  cite  a  number  of  other  cases,  four  that  I  now 
recall,  here  in  Bristol.  I  have  not  known  of  any  case  in  which  the 
powder  has  been  applied  where  there  has  not  been  a  cure ;  of  course, 
there  may  be  mistakes  in  diagnosis,  but  Dr.  Gross  will  hardly  be 
charged  with  making  one. 
The  mode  of  application  has  been  to  lightly  cover  the  surface  with 
the  powder;  apply  over  it,  to  protect  the  powder  and  keep  it  in  place,  a 
piece  of  black  silk,  somewhat  larger  than  the  ulcer  and  made  adhesive 
by  egg  albumen.  Considerable  pain  is,  of  course,  produced  ;  but  the 
first  application,  and  all  subsequent  ones,  is  allowed  to  remain  until 
the  pain  leaves,  which  will  be  in  five  or  six  days.  A  new  one  is  then 
applied  in  the  same  way  and  repeated  from  time  to  time  until  an 
eschar  is  detached  without  force.  A  poultice  of  elm  bark  is  applied 
and  the  ulcer  allowed  to  heal.  It  may  be  the  charcoal  found  by  analy- 
sis is  from  sheep  sorrel,  as  the  person  using  it  was  known  to  collect 
that  plant  on  different  occasions.  While  the  use  of  arsenious  acid  for 
external  application  has  long  been  made,  yet  every  writer  emphasizes 
the  danger  in  using  it  where  the  cuticle  is  removed,  and  I  imagine 
most  physicians  like  myself  have  feared  to  so  use  it.

LINIMENTUM  AMMONLZE  AND  OTHER  LINIMENTS. 
By  Joseph  W.  England,  Ph.G. 
Read  at  the  Pharmaceutical  Meeting,  October  18. 
It  goes  almost  without  saying,  that  the  most  popular  and  generally 
employed  stimulating  and  rubefacient  liniment,  both  amongst  the 
laity  and  the  profession,  is  the  officinal  "  Linimentum  Ammonice,"  or 
the  so-called  ammonia  or  volatile  liniment.  In  many  respects,  the 
U.  S.  P.  (1870)  formula  for  its  making  with  its  two-thirds  volume  of 
olive  oil  and  one-third  volume  of  ammonia  water,  possessed  decided 
advantages  over  the  very  questionable  improvements,  in  the  substitu- 
ting of  cotton-seed  oil  for  olive  oil,  and  the  decrement  in  amount  of 
ammonia  water,  adopted  by  the  last  pharmaeopoeial  committee  of  1880. 
In  the  first  place,  as  has  been  shown  before,  it  is  impossible  to
