A  VcTm™* }     Glycerate  of  Sucrate  of  Lime,  etc.  559 
Powdered  Sugar   400  grams. 
Water   2  kilograms. 
Glycerin   400  grams. 
Mix  the  sugar  and  lime  thoroughly  in  a  mortar  ;  add  the  water  in 
small  portions,  so  as  to  obtain  a  clear  pulp  without  lumps.  Put  the 
mixture  into  a  stoppered  flask.  After  contact  for  twenty-four  hours, 
filter,  and  add  the  glycerin  to  the  solution,  then  evaporate  until  it  is 
reduced  to  one  litre.  It  is  essential  not  to  add  the  glycerin  until  after 
the  filtration  of  the  solution  of  sucrate  of  lime,  or  the  filtration  will 
be  retarded. 
The  glycerate  of  sucrate  of  lime  thus  prepared  has  a  density  of 
1-280  at  15°  C.  It  is  not  coagulated  by  boiling ;  but  coagulation 
takes  place  if  it  be  diluted  with  four  times  its  volume  of  water.  It 
contains,  by  volume,  in  100  cubic  centigrams,  7*716  grams  of  lime, 
corresponding  to  56-55  grams  of  dry  sucrate  of  lime ;  by  weight,  in 
100  grams,  6*720  grams  of  lime,  corresponding  to  49*42  grams  of  dry 
sucrate. 
Applied  to  the  skin  this  glycerate  of  sucrate  of  lime  forms  a  kind 
of  varnish,  which  under  the  influence  of  transpiration  is  detached  in 
the  form  of  lumps ;  upon  inflamed  surfaces  it  produces  a  feeling  of 
coolness  and  comfort.  More  decided  drying  qualities  may  be  im- 
parted to  it  by  dissolving  in  it,  with  heat,  about  3  per  cent,  of 
gelatin. 
Dilute  G-ly cerate  of  Sucrate  of  Lime. — Preparation  of  Chalk  Lin- 
iment.— For  the  preparation  of  chalk  liniment  with  the  glycerate  of 
sucrate  of  lime  it  is  preferable  to  use  a  dilute  solution,  such  as  exists 
before  the  mixture  is  concentrated,  as  directed  in  a  preceding  para- 
graph. It  then  has  a  density  of  1*144  at  15°  C,  and  contains,  by 
volume,  in  100  cubic  centigrams,  3*512  grams  of  lime,  corresponding 
to  26*05  grams  of  dry  sucrate  of  lime ;  by  weight,  in  100  grams, 
3*289  grams  of  lime,  corresponding  to  24*19  grams  of  dry  sucrate. 
The  formula  for  the  liniment  of  the  glycerate  of  sucrate  of  lime  is 
as  follows  : —

By  substituting  oil  of  sweet  almonds,  a  mixture  is  obtained  that  is 
a  little  less  solid.    In  certain  cases  where  it  is  desired  to  combat  the
