bread  and  the  nurture  of  our  flesh  and  bones.  But  I  do  not 
think  that  the  working  classes,  to  whom  it  is  so  very  important, 
will  ever  take  to  it  fully  until  set  the  example  by  the  more  in- 
structed classes,  who  yet  themselves  require  instruction  in  this 
matter.

ON  A  NEW  MACERATING  APPARATUS. 
By  Mr.  R.  W.  Giles. 
The  unostentatious  arrangement  exhibited  before  the  Confer- 
ence, for  the  more  convenient  exhaustion  of  vegetable  substances 
in  a  minimum  quantity  of  water,  having  proved  very  satisfactory 
in  the  preparation  of  infusum  cinchona  spissatum,  and  other 
allied  liquors  of  ordinary  and  extensive  use  in  pharmacy,  I  have 
thought  it  worthy  of  a  few  remarks  at  the  present  meeting.  I  do 
not  desire  to  see  Pharmaceutical  Chemists  become  manufacturers, 
but  I  strongly  believe  that  the  natural  mode  of  advancing  the 
practice  of  pharmacy  amongst  the  many  in  our  profession  is  to 
o;ive  them  a  practical  interest  in  the  processes  of  the  art,  begin- 
ning with  the  most  simple  ;  and  that  the  communication  of  simple 
forms  of  apparatus  which  will  have  the  advantage  of  rendering 
ordinary  processes  easy  and  profitable,  is  one  of  the  best  means 
of  attaining  this  object.  I  may  take  this  opportunity  of  saying 
that  the  establishment  of  a  Museum  of  Pharmaceutical  Apparatus 
at  Bloomsbury  Square  has  long  been  an  object  of  solicitude  to 
me  ;  and  I  trust  that  the  present  exhibition  may  ultimately  re- 
sult in  such  an  institution,  which  we  may  hereafter  consult  with 
advantage  and  economy,  and  the  origin  of  which  we  may  plea- 
santly associate  with  this  our  agreeable  visit  to  Nottingham. 
The  apparatus  needs  little  descripton  to  those  who  have  seen 
the  model.  It  consists  of  a  series  of  eight  cone-shaped  macera- 
tors,  each  provided  with  its  receiver,  and  the  water  used  for 
m  iteration  is  passed  successively  through  the  material  divided 
amongst  the  eight  cones — the  material  being  reduced  to  a  con- 
venient state  of  pulverization,  and  each  maceration  being  con-
