There  is  great  rejoicing  in  Denmark  by  Dr. 
Bang’s  discovery  of  the  bacterium  which  causes 
abortion.  It  remains  now  to  discover  the  best 
way  of  destroying  the  germ,  but  meanwhile  it 
has  been  demonstrated  that  a bull  usetl  for  service 
on  a cow  that  has  aborted  may  infect  any  cow 
he  serves  afterwards. 
In  New  Zealand  the  aeration  of  milk  is  mad® 
compulsory  by  law.  klvery  supplier  of  milk  has 
to  pa.'-s  his  milk  through  an  aerator,  or,  at  al 
events,  remove  the  animal  odour  from  it  im- 
mediately  it  is  drawn  from  tlie  cow.  'J'he  “re- 
frigerator ” which  also  aerates  milk  is  too  expen.sive 
fur  common  use,  but  now  more  than  one  cheap 
aerators  has  been  jiatented.  The  late.^t  on  the 
market  is  the  “Austral,”  which  is  said  to  be 
very  satisfactory  and  cost  only  12s.  GJ. 
The  latest  device  for  pres.erving  eggs  is  toiuh 
them  over  with  the  white  of  egg  and  pack  in 
flour.  By  this  method  both  the  yolk  and  whites 
are  said  to  remain  marvellously  fre.sh  and 
sweet.
