spread  upon  palmetto  leaves  to  dry.  When  dried,  it  is  a  yellowish 
white  flour,  ready  for  use. 
In  the  factories  this  process  is  substantially  followed,  but  with 
improved  appliances,  the  chief  variation  being  that  the  koonti 
starch  undergoes  several  successive  macerations,  thereby  making  it 
purer  and  whiter  than  the  Indian  product. 
The  koonti  bread  made  by  the  Indians  is  of  a  bright  orange  color. 
It  is  rather  insipid,  though  not  unpleasant  to  the  taste.  It  is  made 
without  salt.  Its  yellow  color  is  due  to  the  fact  that  the  flour  has 
had  but  one  maceration. 
NEATSFOOT  OIL. 
J.  H.  Coste  and  E.  J.  Parry  [The  Journal  of  the  Society  of  Chemical 
Industry,  Vol.  xvii,  p.  4)  state  that  very  little  information  of  a  re- 
liable character  has  been  published  concerning  this  oil.  They  at- 
tribute the  deficiency  to  the  difficulty  in  obtaining  genuine  samples. 
Therefore,  in  order  to  supply  trustworthy  data  on  this  subject,  the 
authors  examined  a  sample  (I)  which  was  obtained  through  one  of 
the  most  reliable  trade  sources,  and  two  others  (II  and  III)  which  they 
prepared  themselves  with  special  regard  to  details  for  obtaining  the 
oil  in  a  pure  condition. 
The  following  is  a  summary  of  their  results  :

The  authors  observe  that  the  above  figures  show  that  the  samples 
of  known  neatsfoot  oil  more  closely  resemble  one  another  than 
they  do  the  trade  sample. 
The  fatty  acids  of  these  three  samples  were  obtained  by  saponify- 
ing large  quantities  of  the  oil,  washing  with  water  and  drying  at 
ioo°  C.    An  analysis  of  these  gave  results  as  follows:
