Swiftness of the Thrust, it must have its proper Line and Distance. The
Line must be taken from the Inside of the Left Heel to the Point of the
Adversary's Right Foot; If it turn inward or outward, the Button will
not go so far, the strait Line being the shortest; besides the Body would
be uncovered, for by carrying the Foot inwards, the Flank is exposed,
and by carrying it outwards the Front of the Body, and the Body is
thereby weakened; the Prop and the Body being obliged to form an Angle
instead of a strait Line, from the Heel of the Left Foot to the Point or
Button of the Foil.

In order to know the Distance of the Lunge, the Right Knee being bent,
must form a perpendicular Line with the Point of the Foot; if the Foot
were not so forward, the Heel would be off the Ground, and the Body
would have less Strength, and if it were carried farther the Body could
not easily bend it self, and consequently could not extend so far;
moreover, it would want Strength, being at too great a Distance from the
perpendicular Line of the Foot and Leg, which are its Support, and its
Recovery would be more difficult.

The Foot should fall firm without lifting it too high, that the Soal of
the Sandal, or Pump, may give a smart Sound, which not only looks better
and animates more, but also makes the Foot firm, and in a Condition to
answer the Swiftness of the Wrist.

Care must be taken not to carry the Point of the Foot inward or outward,
because the Knee bending accordingly, as part of the Thigh, goes out of
the Line of the Sword, and consequently, of the Line of Defence, besides
'tis very disagreeable to the Sight.

The Feet sometimes slip in the Lunge, the Right Foot sliding forward, or
