softens  sufficiently  to  allow  of  being  moulded ;  at  a  higher  heat 
it  fuses  partially,  giving  off  white  fumes  with  very  little  odor,  at 
the  same  time  becoming  black  ;  while  cooling  it  is  rather  adhesive 
and  possesses  considerable  elasticity,  both  qualities  being  re- 
tained to  a  certain  degree  for  weeks.  When  approached  to  the 
flame,  it  takes  fire  and  burns  with  a  bright  sooty  flame.  Alcohol 
has  no  eff"ect  on  it ;  ether  and  light  coal  oil  (so-called  benzine) 
dissolve  the  white  portion,  leaving  the  yellowish  part  and  impu- 
rities behind ;  oil  of  turpentine  furnishes  a  turbid  solution  and 
converts  the  yellowish  part  into  a  thick  oily  liquid  ;  chloroform 
and  bisulphide  of  carbon  yield  milk-white  emulsions  without 
efi"ecting  clear  solutions. 
The  substance,  if  obtainable  in  sufficient  quantity,  could  un- 
doubtedly be  used  in  the  arts  for  many  purposes  in  place  of 
gutta  percha.  V
