inclined position insure access of the air to every portion of the
hominy.

It will be noticed that the connection of all the parts is absolute. The
motion of the sieves, the speed of the blower, and the action of the
inlet hopper valve and the delivery hulling valve are always exactly
proportioned to the speed of the hulling cylinder, whether fast or slow.
The upper or feed valve opens upward and has a downward projecting lip
that shuts into a recess in its seat which insures security against
leakage from the hopper to the hulling cylinder during the intervals of
its being raised; a great advantage in hominy making, as no grain ought
to get into the batch until that in the cylinder is done.

Nitro-Glycerin.


Professor Doremus of this city was called as a witness at the inquest
upon the bodies of the unfortunate persons killed by the recent
explosion at Bergen, N.J. The Professor having previously analyzed some
of the explosive mixture, testified as follows:--"I have subjected it
to chemical analysis, and find it to correspond to the formula C_{6},
H_{3}, O_{3}, and NO_{5}; it is well made nitro-glycerin; the substance
