ANALYSIS OF OIL-CAKE. 



FODDER."" In analysing a sample of oil-cake for 

 fodder, the proximate constituents to be determined are 

 six in number . ( i) Moisture ; (2) Ash ; (3) Fibre; (4) Oil; 

 (5) Albuminoid and (6) Soluble organic matter. In powder- 

 ing oil-cake, grains, etc. preparatory to analysis, Messrs. 

 Baird and Tatlock's Analytical Grinding Mill (price -15) 

 should be used.
