CLARIFICATION  OF  SACCHARINE  LIQUIDS.

inches.  The  plant  is  also  found  in  the  north  of  the  Crimea  and 
in  the  southern  part  of  Bessarabia,  but  in  general  it  is  more 
common  in  the  eastern  part  of  the  prairie  region  near  the  Wolga, 
and  to  the  east  of  this  river.  To  dig  out  the  roots  is  very  diffi- 
cult, because  the  subsoil  is  hard  and  cannot  be  worked  with  a 
pickaxe.  The  root  penetrates  the  soil  and  subsoil  in  a  nearly 
perpendicular  line  ;  the  longest  roots  are  discovered  on  steep 
river  banks,  which  are  underwashed  each  spring-time  by  the 
swollen  rivulets  and  also  after  heavy  rains,  the  latter  occurring 
very  seldom.  A  small  number  of  tanners  have  begun  to  employ 
the  roots  of  Statice,  but  as  the  supply  is  precarious  and  the 
leather  tanned  with  them  brittle,  no  progress  is  made  in  utiliz- 
ing this  tanning  material,  which  in  more  skilful  hands  has 
proved  one  of  the  best,  as,  for  instance,  in  Spain." — Lond.

A  NEW  METHOD  OP  CLARIFYING  SACCHARINE  LIQUIDS, 
JUICES  AND  SYRUPS,  AND  OF  REVIVIFYING  THE  ANIMAL 
CHARCOAL  USED  IN  THE  MANUFACTURE  OF  SUGAR, 
By  H.  Leplay  and  J.  Cusinter. 
Of  late  years,  most  of  the  improvements  in  the  manufacture 
of  sugar  have  been  directed  to  the  disuse  of  animal  charcoal. 
Having  for  many  years  witnessed  the  services  which  animal 
charcoal  has  rendered,  and  still  renders,  we  have  directed  our 
researches  in  a  direction  entirely  different.  Our  principal  ob- 
ject has  been  to  analyse  the  action  exercised  by  animal  char- 
coal on  saccharine  liquids  at  each  stage  of  the  manufacture,  the 
duration  of  this  action,  and  its  exhaustion.  We  have  sought  to 
restore,  by  easy  and  speedy  methods,  the  absorbing  properties 
it  loses  by  use,  and  to  ascertain  the  cause  of  its  various  absorb- 
ing properties,  on  which  chemistry  hitherto  has  thrown  but  little 
light.  This  cause  being  discovered,  we  can,  so  to  speak,  in- 
crease it  at  will,  and  thus  effect  in  saccharine  liquids,  juices, 
and  syrups,  a  greater  degree  of  purification  than  can  be  obtained 
by  the  ordinary  means. 
This  study  has  led  us  to  the  discovery  of  a  new  method  for 
refining  saccharine  liquids,  and  of  revivifying  animal  charcoal,
