III.— EXPERIMENT  ON  THE  COLOURING  OF  MILK 
AND  BUTTER. 
Demonstrations  with  coloured  milk  and  butter,  having  for 
their  object  the  testing  of  the  knowledge  of  the  public  on  the 
subject,  were  carried  out  on  the  same  lines  as  at  previous 
Shows  of  the  Society  and  with  similar  results.  On  each 
occasion  it  was  pointed  out  that  if  a guarantee  could  be 
obtained  from  the  vendor  that  the  articles  offered  for  sale, 
whether  milk  or  butter,  were  not  coloured  artificially,  the 
purchaser  would  be  safe  in  concluding,  all  other  conditions 
being  equal,  that  the  deepest  coloured  milk  or  butter  would  be 
the  best  both  in  flavour  and  quality. 
It  may  be  remembered  that  at  the  Show  at  Gloucester  a 
Tintometer  was  used  to  measure  the  colours  of  various  butters. 
Through  the  kindness  of  Mr.  J.  W.  Lovibond  the  apparatus 
was  again  lent  to  the  Society,  and  at  Liverpool  it  was  decided 
to  examine  various  samples  of  milk  and  see  if  it  was  possible 
to  obtain  any,  and  what,  information  from  the  colours  developed 
through  the  Tintometer. 
Three  samples  of  milk  were  dealt  with  : 
1.  Devon. 
2.  Separated  milk  coloured  with  annato  to  resemble  the 
Devon  milk. 
3.  Separated  milk  not  coloured.
