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.

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