196 ANALYSES OF MAIZE. 



9. Analysis of the phosphates of the cob. 

 Phosphates --—-.- 2 '810 



Soluble silica 0020 



Lime 0-250 



Magnesia 0'579 



Phosphate of peroxide of iron ... 0-120 



Phosphoric acid ------ 1-871 



2-S40 



On consulting' the proportion of inorganic or earthy matter in the cob, it will be seen 

 that it is small ; still when the question respecting the nutritive value of the cob is dis- 

 cussed, it is proper to take this into account. It is particularly rich in phosphates and 

 other alkalies : so we have an additional reason for feeding the cob in conjunction with 

 the grain.

 11. Organic analysis of the dry cob of the small 8-rowed yellow corn: cut August 11. 



Per centum.

Sugar and extract - - - - - - 7-25 



Oil and resin - - - - - - - l'OO 



98-78 



The amount of soluble matter in the cob exceeds what was expected when I commenced 

 the analysis; and it may still exceed considerably what is here stated, inasmuch as it is 



• Obtained by sifting nut tlin mtirlo from coarsely ground mm : Iiptipp not entirely f'rno from the farinaceous matter.
