250-0  distilled  water  and  50-0  spirit  of  cognac  and  then  8oo-0  boil- 
ing simple  syrup  added  ;  the  vessel  is  covered,  set  aside  for  15  min- 
utes in  a  moderately  warm  place,  and  after  standing  at  ordinary 
temperature  for  24  hours,  the  liquid  is  filtered.  This  formula  gives 
a  superior  product,  if  the  directions  are  followed  closely. — E.  Diete- 
rich,  Pharm.  Centralhalle,  1890,  160. 
Adhesive  masses  for  plasters,  intended  to  increase  the  adhering 
property  of  plasters,  may  be  made  with  rubber  or  gutta-percha  as 
the  base.  Massa  emplastica  cummea. — 10  parts  rubber,  in  fine 
shreds,  are  added  to  a  melted  mixture  of  25  parts  anhydrous  lanolin 
and  25  parts  resin,  stirring  with  an  iron  spatula  and  heating  mod- 
erately at  first,  afterwards  to  180-2000  C,  until  the  rubber  is  com- 
pletely dissolved  ;  25  parts  resin  and  10  parts  dammar  resin  are 
now  added,  and  heat  is  applied  until  a  homogeneous  mixture  is 
obtained,  which  is  poured  into  porcelain  vessels  and  set  aside  for 
use.  Massa  emplastica  perchata  differs  from  the  other  mass  only  in 
having  gutta-percha  instead  of  rubber.  The  gutta-percha  is  softened 
by  kneading  under  hot  water,  drawn  out  into  thin  ribbons,  and  cut 
into  shreds  before  adding  it  to  the  melted  lanolin  and  resin.  The 
addition  of  25  per  cent,  of  these  masses  to  the  regular  plaster  mass 
will  cause  the  plaster  to  adhere  to  the  body  for  weeks ;  should  the 
plaster  contain  mineral  oils,  30  per  cent,  of  the  adhesive  masses 
should  be  added.  The  anhydrous  lanolin  is  of  especial  value  in 
absorbing  the  moisture  eliminated  by  the  body,  so  maintaining  the 
adhesive  property  of  the  plaster. — H.  Hager,  Pharm.  Ztg.,  1890,
