ANALYSES OF MAIZE.

it is very liable to end in fusion. The best mode of proceeding, when the ash begins to 
appear, is to remove it from the lire which is in common use, and which usually requires 
to be kept in a lively state while the work is going on; and then at the approach of 
evening, when the heat of the stove is considerably diminished, to replace it, and suffer 
it to remain during the night. In the morning it will be found to have made considerable 
progress. Proceeding in this way for a week or more, a good ash for analysis will be 
obtained. Another requisite is a perfectly dry state of the corn : at least, very dry corn 
has burnt better than that which was moist at the beginning. The same mode of pro¬ 
cedure will be successful in wheat and its flour, or indeed in any of the cereals. Oat3 and 
barley, however, are not very difficult to burn.
