At midnight began the modish music of the dance, and groups of beautiful girls moved like the atoms of Chladni on the vibrating crystal, with their partners, to the sound of harps and violins, in pleasing figures or inebriating spirals.

The same property is well illustrated by an elegant and easily repeated experiment of Chladni's.

Chladni's figures, he seemed to remember, they were called after their discoverer.

The beauty of harmony is an instinct in us; it lies in our eyes and in our ears, those bridges between our soul and the creation around usin all our senses there is such a divine, such an entire and perfect stream in our whole being, a striving after the harmonious, as it shows itself in all created things, even in the pulsations of the air, made visible in Chladni's figures.

CHLADNI, FRIEDRICH, a physicist, born at Wittenberg; one of the earliest investigators of the phenomena of sound; wrote also on aërolites (1756-1827).
