ush _Quart_ within, besides the Precautions of placing yourself to
Advantage, and of pushing properly and swiftly, which is to be acquired
by Practice and nice Speculation, It is necessary that the Parts, in
order to assist each other in making the Thrust, should be so disposed
and situated, as that the Wrist should draw with it the Bend of the Arm,
the Shoulder, and the upper Part of the Fore-Part of the Body, at the
same time that the Left Hand and Arm should display or stretch
themselves out smartly, bending one of the Knees and extending the
other, which gives more Vigour and Swiftness to the Thrust; and the Body
finding itself drawn forward by the swift Motion of the Wrist and other
Parts, obliges the Right Foot to go forward in order to support it, and
to give the Thrust a greater Length; the Left Foot should, at the same
Instant, turn on the Edge, without stirring from its Place; whilst the
Right Foot coming smartly to the Ground, finishes the Figure, Extension
and Action of the Lunge. This is the Order and Disposition of the Parts
in making the Thrust, which see in the second Plate. At the Instant when
the Wrist moves forward, it must do three things, turn, support and
oppose.

To turn the Wrist in _Quart_, the Thumb Nail must be up, and the inside
Edge equal in Height with the other, for if it were not so high, the
Thrust would not be so swift, for want of Motion enough, neither would
the Body be so well covered, because the Edge, instead of being directly
opposite to the Adversary's Sword, would fall off with a Slant; and if
it were higher, it would make a Quint Figure, which, by the excessive
Turn of the Wrist, would weaken the Thrust, and by the unequal Turn of
the Edges would uncover the Body.

The Wrist ought to be of a Height sufficient to cover the Body without
contracting the Arm, which cannot be fixed to a particular Height; for a
short Man against a tall one, should raise it as high as the Head, which
People of equal; Stature, or a tall Man against a short one, ought not
to do.

When the Opposition is accompanied with such a Turn and Support of the
Wrist as will cover the Body, it is good, but if the Wrist be carried
too far in, you not only lose Part of the Length of the Thrust, but also
uncover the Outside of the Body, which are two very great Faults.

The Thrust must be made on the Inside of the Right Shoulder, in order to
take the Feeble with your Fort, and that you may be covered, bearing on
