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 fire 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 nigbt. 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. Oats and 

 barley, however, are not very difficult to burn.
