Bougies.  Bougies  containing  sulphate  of  zinc,  sulphate  of  copper, 
nitrate  of  silver,  extract  of  opium,  hydrochlorate  of  morphine,  bichlo- 
ride of  mercury,  etc.,  are  made  as  follows  :  one  part  of  sulphate  of 
zinc,  or  any  of  the  above-mentioned  medicaments  is  first  dissolved  in 
a  little  water,  and  then  added  to  99  parts  of  mass  No.  IV,  and  poured 
into  moulds.  If  it  is  desired  to  make  a  large  quantity  of  sulphate  of 
copper  bougies  it  is  best  to  mix  not  more  than  the  mould  will  hold  at 
a  time,  because  by  frequently  heating  the  mass  the  bougies  acquire  a 
yellowish-green  color  instead  of  a  blue-green. 
Bougies  of  carbolic  acid  (5  per  cent.),  and  similar  medicaments  so- 
luble in  a  small  quantity  of  alcohol  are  made  by  adding  3  parts  of 
carbolic  acid  previously  dissolved  in  alcohol  to  7  parts  of  glycerin  and 
50  parts  of  mass  No.  III. 
Bougies  of  iodoform  50  per  cent,  and  of  similar  medicaments  inso- 
luble in  water  and  alcohol  by  adding  27  parts  of  powdered  iodoform 
to  54  parts  of  mass  No.  V.  When  taken  from  the  mould  the  bougies 
rare  placed  in  a  drying  closet  until  they  weigh  about  two-thirds  of 
their  original  weight. 
Bougies  of  ferric  chloride  (5  per  cent),  and  of  similar  hygroscopic 
drugs  by  dissolving  1  part  of  sesquichloride  of  iron  in  9  parts  of 
water,  and  adding  to  19  parts  of  mass  No.  II. 
Alum  bougies  (2  per  cent),  25  parts  of  mass  No.  Ill,  and  10  parts 
of  distilled  water  are  liquefied  in  water  bath.  To  this  is  added  a  hot 
solution  of  7  parts  of  alum,  10  glycerin  and  5  distilled  water.  The 
whole  is  then  evaporated  with  slight  agitation  to  35  parts.  The  mixture 
becomes  thick  and  turbid  on  adding  the  solution  of  alum,  but  on  heat- 
ing over  a  water  bath  and  stirring  carefully,  the  mixture  soon  becomes 
clear  and  transparent.  Hot  water  must  be  added  from  time  to  time 
to  replace  that  lost  by  evaporation. 
Bougies  containing  tannin  *2  per  cent.  0*66  of  tannin  is  dissolved  in 
8  glycerin,  and  the  hot  solution  added  to  39  mass  No.  II,  the  whole 
evaporated  to  33.  The  mass  will  coagulate  on  the  addition  of  the 
tannin  solution,  but  becomes  clear  when  slowly  stirred  for  5  or  10 
minutes  on  a  water-bath.  By  this  process  2  grams  of  tannin  may  be 
incorporated  with  5  grams  of  gelatin.  This  formula  is  a  very  good 
one,  and  yields  bougies  which  are  very  soluble.  Schreiber  states  that 
he  has  met  with  tannin  bougies  which,  on  boiling  with  water  for  half 
an  hour,  did  not  dissolve. 
Bougies  of  extract  of  krameria  are  not  made  with  gelatin  but  with
