19^ ANALYSES OF MAIZE. 



9. Analysis of the phosphates of the cob. 

 Phosphates - - • - - - 2'840 



Soluble silica 0-020 



Lime 0-250 



Magnesia ---•-.. 0-579 



Phosphate of peroxide of iron - - - 0-120 



Phosphoric acid - - - - - - 1-871 



2-840 



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 com: cut .August 11. 



Per centum. 



Insoluble matter or fibrin - - - - 86-74 



Albumen 1*94 



Casein 0-64 



Dextrine or gum ...-.- 1-21 



Sugar and extract - - • - • - 7-25 



Oil and resin - 1-00 



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 oirtinK out the cuticle from coarsely ground com : hence not entirely free from the farinaceous matter.
