present  time,  which  is  about  two  months,  a  sample  of  the  mixture  has 
remained  permanent  and  shows  no  sign  of  separation. 
Apropos  of  the  subject  of  liniments,  a  change,  or,  more  correctly,  a 
return  to  the  older  method  in  the  officinal  formula  for  the  linimentum 
calcis,  of  our  present  pharmacopoeia,  is  most  strongly  urged  by  the 
writer.  As  is  well  known,  this  emollient  and  protective  emulsionized 
liquid,  used  almost  wholly  for  applications  to  recent  and  superficial 
burns,  especially  in  the  ulcerative  stage,  where  it  acts  not  only  as  a 
protective,  but  also  as  an  astringent,  is  directed  to  be  prepared  with 
equal  parts  of  cotton -seed  oil  and  lime  water.  Now,  the  same  objec- 
tions, previously  mentioned,  which  apply,  to  cotton-seed  oil  in  the  case 
of  linimentum  ammonioz  apply  in  a  much  greater  degree  to  the  use 
of  that  fixed  oil  in  this  instance  ;  especially  when  we  consider  the  re- 
latively small  quantity  of  calcium  hydrate  contained  in  lime  water. 
The  old  formula  for  "  carron  oil,"  with  its  one-half  linseed  oil  and 
one-half  lime  water,  each  by  volume,  is  thoroughly  recognized  and 
used  everywhere,  in  lieu  of  the  present  pharmacopceial  product,  and 
the  use  of  that  preparation — if  indeed  it  ever  obtained  a  foothold  in 
the  profession,  which  is  questioned — has  certainly  fallen  into  a  state 
of  "  innocuous  desuetude"  and  the  query  naturally  suggests  itself, 
Would  it  not  be  better  for  our  officinal  standard  to  recognize  this 
time-worn  and  time-tried  formula,  whose  usage  runs  the  world  wide, 
in  place  of  this  inefficient  substitute  which  fails  to  fulfill  its  intended 
object  ? 
•  Without  question,  one  of  the  best  turpentine  liniments  of  the  day 
is  that  milk-white  liquid,  St.  John  Long's  Liniment.  It  has  achieved 
deserved  popularity,  and  when  carefully  made  nothing  can  be  said 
against  it ;  but  there  is  one  feature,  in  connection  with  its  making,  that 
greatly  interferes  with  its  more  general  employment,  and  that  is  the 
difficulty,  at  times,  of  obtaining  good  eggs,  and  then,  when  obtained,  of 
perfectly  suspending  the  very  large  percentage  of  oil  of  turpentine. 
To  obviate  this  trouble  the  writer  has  devised  a  modified  formula, 
without  the  use  of  eggs  or  acetic  acid.  Owing  to  the  presence  of  the 
excess  of  stimulating  ammonia  gas,  the  volatile  oil  has  been  slightly 
reduced  in  quantity  from  the  original  formula.
