[PHOSPHORUS WAS DISCOVERED IN 1677.]

148. Valse Cellarius.

The gentleman takes the lady's left hand with his right, moving one
bar to the left by _glissade_, and two hops on his left foot, while
the lady does the same to the right, on her right foot; at the second
bar they repeat the same with the other foot--this is repeated for
sixteen bars; they then waltz sixteen bars, _glissade_ and two hops,
taking care to occupy the time of two bars to get quite round. The
gentleman now takes both hands of the lady, and makes the grand
square--moving three bars to his left--at the fourth bar making two
beats while turning the angle; his right foot is now moved forward to
the other angle three bars--at the fourth, beat again while turning
the angle; the same repeated for sixteen bars--the lady having her
right foot forward when the gentleman has his left toot forward; the
waltz is again repeated; after which several other steps are
introduced, but which must needs be seen to be understood.

149. Circular Waltz.

The dancers form a circle, then promenade during the introduction--all
waltz sixteen bars--set, holding partner's right hand, and turn--waltz
thirty-two bars--rest, and turn partners slowly--face partner and
chassez to the right and left--pirouette lady twice with the right
hand, all waltz sixteen bars--set and turn--all form a circle, still
retaining the lady by the right hand, and move round to the left,
sixteen bars--waltz for finale.

150. Polka Waltzes.

The couples take hold of hands as in the usual waltz.

_First Waltz_. The gentleman hops the left foot well forward, then
hack; and _glissades_ half round. He then hops the right foot forward
and back, and _glissades_ the other half round. The lady performs the
same steps, beginning with the right foot.

_Second._ The gentleman, hopping, strikes the left heel three times
against the right heel, and then jumps half round on the left foot; he
then strikes the right heel three times against the left, and jumps on
the right foot, completing the circle. The lady does the same steps
with reverse feet.

_Third._ The gentleman raises up the left foot, steps it lightly on
the ground forward, then strikes the right heel smartly twice, and
_glissades_ half round. The same is then done with the other foot. The
lady begins with the right foot.
