I  have  not  added  additional  data,  since  they  can  be  ea'sily  calcu- 
lated from  the  above. 
These  samples  of  beeswax  are  curiosities,  and  if  the  specimens  alone 
existed,  it  would  be  well  and  good,  but  that  they  represent  hun- 
dreds of  pounds  in  this  market  is  a  deplorable  fact. 
PETROLATUM  MOLLE.   
The  U.  S.  P.  requires  this  product  to  be  ointment-like  in  consist- 
ence, odorless,  tasteless,  with  a  melting  point  varying  from  400  to 
45°  C,  and  a  specific  gravity  ranging  from  0-820  to  o  840,  at  6o°  C. 
It  should  be  completely  volatilized  when  heated  on  a  piece  of  plati- 
num without  emitting  any  acrid  vapors,  and  be  free  from  resin  and 
saponifiable  fats  and  oils.  When  one  volume  of  petrolatum  is  treated 
with  two  volumes  of  concentrated  sulphuric  acid  in  a  test-tube 
placed  in  hot  water  and  agitated  occasionally  during  fifteen  minutes, 
the  acid  should  neither  acquire  a  deeper  tint  than  brown  nor  lose 
its  transparency. 
The  following  table  contains  the  analytical  results  of  nine  samples 
of  petrolatum  molle  :

Each  sample  completely  volatized  on  platium  foil  without  any 
acrid  vapors,  was  ointment-like  in  consistence,  neutral  and  soluble 
in  its  various  solvents.
