plan  to  succeed  admirably,  namely,  to  agitate  each  quart  of  water  with 
an  ounce  of  phosphate  of  lime,  and  allow  it  to  settle.  This  only 
requires  a  few  minutes,  and  it  will  be  found  that  most  of  the  impurities 
are  carried  down  to  the  bottom.  The  supernatant  water  is  now  filtered 
without  any  trouble  through  absorbent  cotton.  Ordinary  cotton  will 
answer  as  well,  if  previously  moistened  with  alcohol  and  then  washed 
with  water.  Of  course,  either  of  them  must  be  pressed  tightly  into 
the  neck  of  a  funnel.  By  this  means  perfectly  clear  water  can  be 
obtained  in  about  five  minutes. 
J  Good  Filling  for  Teeth. — A  filling  that  has  been  used  very  success- 
fully for  teeth,  and  which  is  next  to  gold  leaf  in  permanency,  is  made 
of  the  following  ingredients  : 
R     Oxide  of  zinc  (recently  made  by  burning),  .    200  parts 
Powdered  silica,    ....  8 
borate  of  soda,  .  .  .4 
glass,     .  .  .  .  5 
Mix  and  pass  through  a  very  fine  sieve.  To  be  kept  in  a  well  stop- 
pered bottle. 
When  required  for  use,  a  little  of  the  powder  is  mixed  quickly  with 
a  concentrated  solution  of  chloride  of  zinc,  so  as  to  make  a  thick 
paste,  which  is  pressed  into  the  cavity  of  the  tooth,  and  will  harden  in 
less  than  ten  minutes.  It  forms  a  hard  white  cement,  which  will  last 
for  years. 
Cosmetic  Pomade  can  be  made  by  the  following  formula  : 
White  wax,  .  .  .  -4?  ozs.  avoir. 
Lard,      .....  4!] 
,  Balsam  of  Peru,  .  .  .  .1  drachm 
Oil  of  orange  flowers,  .  .  .30  drops 
lavender,  .  .  .  .5 
cloves,         .  .  ,  .6 
rosemary,  .  .  .  .5 
Melt  the  lard,  wax  and  balsam,  and  stir  them  constantly  until  they 
thicken,  when  the  oils  are  added.  This  is  then  poured  into  moulds  ; 
when  cold,  wrap  up  each  stick  in  wax  paper  and  tinfoil. 
Black  stick  pomade  is  made  by  mixing  40  grains  of  best  lampblack, 
carefully  rubbed  up  with  a  portion  of  the  lard. 
Brown,  by  using  burnt  sienna  in  same  way,  and  various  shades  of 
brown,  by  mixing  burnt  sienna  with  lampblack. 
Camphoric  Acid  can  be  produced  by  boiling  camphor  with  fifteen  or 
sixteen  parts  of  strong  nitric  acid,  in  a  suitable  glass  vessel,  for  twenty
