II.  Stir  3  pounds  of  acetate  of  lead
into  2  gallons  of  water  and  slake  6
pounds  of  freshly  burned  lime  in  the
liquor.  The  plumbiferouslime  formed
in  this  manner  is  brought  into  50  gal-
lons of  water  and  tiie  fluid  allowed  to
become  clear  by  standing,  when  it  is
ready  for  use.
The  cotton  material  is  then  moistened
twice  in  succession  with  one  of  the
above  fluids,  and,  while  still  moist,
brought  into  a  bath  of  chromate  of
potash.  This  gives  a  beautiful  chrome
yellow  color.
A  beautiful  green  is  obtained  by  dve-
ing  indigo-blue  cotton  goods  in  the
above  manner.
To  Dye  Wool,  Silk,  and  Cotton
WITH  Aniline  Colors.
*>  MLchHne  on  Wool,    In  using  aniline


colon  it  IS  of  the  greatest  advantage  to
transform  them  by  dissolution  into  a
verv  much  diluted  fluid.  For  instance
fucnsine,  soluble  in  water,  is  dissolved
with  grskdual  stirring  in  boiling  water
in  the  proportion  of  2  pounds  of  crys-
tallissed  fuchsine  in  60  gallons  of  water.
The  resulting  solution  is  filtered  and
used  for  dyeing.  The  wool,  uniformly
moistened,  is  dyed  without  any  further
preparation  in  a  verv  clean,  tepid
oath  of  85°  F.  to  which  some  solution
of  fuchsine  is  added  from  time  to  time,
and  the  temperature  raised  to  120°  F.
Two  j)Ounds  of  fuchsine,  soluble  in  alco-
hol, IS  gradually  dissolved  in  4  to  4^  gal-
lons of  good  spirit  of  wine  of  90  per  cent.,
previously  heated  to  100°  to  120°  F..
and  the  solution  used  for  printing  ana
dyeing.  For  printing  on  silk  and  wool
the  ordinary  inspissations  are  used,
such  as  gum,  etc.,  but  on  cotton  it  is
necessary  to  use  albumen,  which  should
always  be  preferred  to  its  substitutes.
