color  and  satiny  lustre,  and  named  by  Dr.  Anderson,  rottlerine. 
Alcohol  extracts  its  medicinal  constituents  most  perfectly,  and

ble for  administration.  Its  formula  on  analysis  is  found  to  be

Medical  Uses. — Kamela  has  been  successfully  given  in  cases 
of  taenia,  and  Dr.  Mackinnon  considers  it  of  much  greater  value 
in  those  cases  then  either  Kousso  or  Turpentine.  Dr.  Ander- 
son describes  "ninety-five  cases  of  taenia,  in  ninety-three  of 
which  th,e  worms  were  expelled  after  the  third  or  fourth  dose." 
It  has  been  used  also  with  very  great  success  for  tapeworm  and 
ascarides  by  Dr.  Arthur  Leared,  of  the  Great  Northern  Hospi- 
tal, and  by  Dr.  William  Moore,  of  Dublin.  The  "Lancet,"  of 
May  15th,  1858,  records  six  cases  of  cure  of  tapeworm  by  Dr. 
Ramskill,  of  the  Royal  Free  Hospital.  In  some  instances  sick- 
ness, headache  and  purging  are  produced  by  it,  but  generally 
its  adminstration  is  attended  by  no  unpleasant  result.
