Analyses of Ashes of Plants. 
We now come to consider the mineral matter in the different 
parts of wheats and first as to its quantity. The following tables 
give the amount of variation in the ash of all the specimens before 
described.

It will be convenient to consider in the first place the quantity 
of ash in the straw and chaff, in order that the mineral matter of 
the grain, both as regards its quantity and quality, may come 
under our notice at one time. 
The quantity of ash of wheat straw is usually comprised witliin 
the limits of 3*5 and 5 per cent, of its weight. There are, as will 
be seen by the table, deviations from this proportion — one speci- 
men (No. 45) giving only 2*74 per cent., whilst in Piper's thick- 
set (Spec. 32) the per centage is as high as 11 .
