There  is  marked  dilatation  of  the  pupils  ;  the  sleep  is  quiet,  re-

it  is  a  remarkable  sedative.  Habituation  is  easily  obtained,  and  the

FILTRATION  OF  MILK. 
In  several  European  cities  sand  filtration  of  milk  is  employed  at 
a  central  depot  after  its  arrival  from  the  country.  The  filters  con- 
sist of  large  cylindrical  vessels,  divided  by  horizontal  superposed 
compartments,  of  which  the  middle  three  are  filled  with  fine  clean 
sand,  sifted  into  three  sizes,  the  coarsest  being  placed  in  the  lowest 
and  the  finest  in  the  topmost  of  the  three  compartments. 
The  milk  enters  the  lowest  compartment  through  a  pipe  under 
gravitation  pressure,  and,  after  having  traversed  the  layers  of  sand 
from  below  upward,  is  carried  by  an  overflow  to  a  cooler  fed  with 
ice  water,  whence  it  passes  into  a  cistern,  from  which  it  is  directly 
drawn  £n.to  locked  cans  for  distribution.  Milk  thus  treated  is  not 
only  freed  from  dirt,  but  the  number  of  bacteria  is  reduced  to  about 
one-third.  In  new  milk  the  loss  of  fat  is  said  to  be  very  slight,  but 
the  quantity  of  mucus  and  slimy  matter  retained  in  the  sand  is 
surprising.  The  sand  is  renewed  each  time  the  filter  is  used. —
