process  any  amount  of  pulp  can  be  prepared  in  a  very  few  moments,

Washing  Precipitate. — This  process  I  have  only  used  on  precipi- 
tates of  iron,  but  have  no  doubt  but  that  it  will  work  on  any  precipi- 
tate equally  well.  After  forming  my  precipitate,  I  pour  it,  superna- 
tant liquid  and  all,  in  wliat  is  known  as  a  two-bushel  bag  ;  this,  after 
folding  over  the  top,  I  put  into  an  ordinary  drug  press  and  apply  a 
very  gradual  pressure  until  the  greater  portion  of  the  liquid  is  pressed 
out,  being  careful  not  to  press  too  hard,  for  if  too  much  pressure  were 
applied  it  would  cake  and  be  difficult  to  wash.  The  washing  is  per- 
formed simply  by  a  repetition  of  the  above,  adding  water,  stirring 
in  the  bag  and  pressing.  By  the  above  I  can  prepare  a  precipitate  in 
nearly  as  many  minutes  as  it  takes  hours  in  the  ordinary  way  of 
•decantation,  etc. 
Elixir  of  Gentian  and  Chloride  of  Iron. — If  extract  of  gentian, 
prepared  after  the  formula  of  the  U.  S.  P.  be  used  in  making  this 
■elixir,  no  difficulty  will  be  experienced,  whether  employing  the 
so-called  tasteless  tincture  of  iron  or  the  ordinary  tincture.  —  Canad,

How  Milk  Should  be  Takex.— Milk  is  a  food  tliat  should  not  be  taken 
in  copious  drauglitJB  like  beer,  or  other  lliiids,  which  differ  from  it  chemi- 
<3ally.  If  we  consider  the  use  of  milk  in  infancy,  the  physiological  inges- 
tion, that  is,  of  it,  we  find  that  the  sacking  babe  imbibes  little  by  little  the 
natural  food  provided  for  it.  Each  small  mouthful  is  secured  by  effort, 
and  slowly  presented  to  the  gastric  mucous  surface  for  the  primal  digestive 
stages.  It  is  tbus  gradually  and  regularly  reduced  to  curd,  and  the  stomach 
is  not  oppressed  with  a  lump  of  half-coagulated  milk.  The  same  principle 
should  be  regarded  in  the  case  of  the  adult.  Milk  should  be  slowly  taken 
in  mouthfuls,  at  short  intervals,  and  thus  it  is  rightly  dealt  with  by  the 
gastric  juice.  If  milk  be  taken  after  other  food,  it  is  almost  sure  to  burden 
the  stomach,  and  to  cause  discomfort  and  prolonged  indigestion,  and  this, 
for  the  obvious  reason  that  there  is  insufficient  digestive  agency  to  dispose 
of  it.  And,  the  better  the  quality  of  the  milk,  the  more  severe  the  discom- 
fort will  be  under  these  conditions. — Dr.  Dr/ce  Duckworth  in  Popular

Forest  Culture. — Probaby  fifty  years  hence  there  will  be  abundance 
of  trees  in  the  West.  Agriculturists  are  rapidly  awaking  to  the  necessity 
of  planting  them.    The  Fort  Scott  and  Gulf  Railroad  Company  has  begun
