242  Annual  Report  of  the  Consulting  Chemist  for  1882. 
to  the  food  upon  which  milch  cows  are  fed  has  been  found  to 
increase  perceptibly  the  yield  of  milk. 
The  manuring  properties  of  malt-combs  are  fully  equal  to 
those  of  linseed-cake  of  fair  average  composition. 
Home-made  Malt. — A sample  of  home-made  malt  sent  by  a 
Member  of  the  Royal  Agricultural  Society  had  the  following 
composition : — 
Moisture 8*15 
Oil 1-67 
Glucose 1 • 88 
"Starch  and  dextrin 70  "87 
* Albuminous  compounds 9 " 81 
Woody  fibre  (cellulose) 5 "07 
Mineral  matters  (ash)  2 • 55 
100-00 
* Containing  nitrogen 1 • 57 
Russian  Linseed-cake. — Good  linseed-cake  on  an  average 
contains  from  26  to  28  per  cent,  of  albuminous  compounds.  In 
Baltic  linseed-cake  the  proportion  of  these  compounds  usually 
is  higher  than  in  cake  made  from  East  India  linseed  ; and  30  to 
33  per  cent,  of  albuminous  compounds  is  not  an  exceptional 
percentage  in  cake  made  from  St.  Petersburg  or  Riga  linseed. 
The  highest  proportion  which  I ever  found  in  linseed-cake 
amounted  to  36"62  per  cent.,  and  occurred  in  a sample  of  Russian 
linseed-cake  which  had  the  following  composition : — 
Moisture 11*13 
Oil 10"73 
* Albuminous  compounds  (flesh-forming  matters)  ..  36  "62 
Mucilage,  sugar,  and  digestible  fibre  28  "22 
Woody  fibre  (cellulose) 7 "91 
Mineral  matter  (ash)  5*39 
100*00 
* Containing  nitrogen  5 -86 
This  was  a pure  linseed-cake,  remarkably  rich  in  albuminous 
compounds,  and  contained  a full  average  percentage  of  oil.  It 
was  sold  at  11.  15s.  per  ton,  free  on  rail  in  London. 
Poisoning  by  White-Lead  Paint.  — A gentleman  who  lost 
several  yearling  calves  sent  me  a white  pasty  substance,  about 
1J  lb.  of  which  was  found  in  the  stomach  of  two  yearlings. 
The  examination  of  this  material  showed  that  it  was  white- 
lead  paint.  Animals  appear  to  be  fond  of  oil-paint,  which  con- 
tains lead,  for  poisoning  cases  with  lead  paints  have  frequently 
been  brought  under  my  notice.  Attention  is  therefore  directed
