ed from the Breech of the Piece unto the Board, directly over the sight and button; and the fire being given (the charge being but eight grains of Powder as before) the Bullet did fully hit the mark. Secondly, the Piece (charged and levelled in the same manner) was laid at the end of the Hearth next the Park, so that very little of the corner R, rested against it, and then the Bullet miss'd the mark about an inch and a quarter towards the Park, or A. The like being done at the other end of the Hearth, the Bullet then miss'd the mark as much the other way; and afterwards with double that charge something more, as before I had found it less with a smaller charge.

Since this (at first designing only to experiment the several distances that the Bullet is carried wide of the mark with different charges of Powder) I made these Experiments following.

In the first Column whereof you have the corner stopt from recoiling.

In the second the grains of Powder with which the Piece was charged.

In the third the distance the Bullet was shot wide from the mark in inches, tenths, and parts of tenths.

In the fourth the side on which the Bullet was carried.

In the last the distance of the mark from the muzzle of the Gun in feet.
