"Atoms have each a different and definite pitch, at which they naturally vibrate.

Scholium: **atomic pitch** is determined directly from its simple spectrum.

Scholium: **atomic pitch** is determined by computations from its associate spectrum with all other atoms, as in known spectra.

Scholium: **atomic pitches** are more important working data than Atomic weights; tables of **atomic pitches** must be precise. [Law of Atomic Pitch]

"The higher harmonics and overtones of projected rad-energy are of a pitch sufficiently high to cause the atom to expand; by causing the atomoles to vibrate systematically the same influence will cause the atom to contract, and thus by changing the volume, **atomic pitch** is varied." [Law of Variation of Atomic Pitch by Rad-energy]

"Electricity and Magnetism produce internal vibrations in the atom, which are followed by proportional changes in volume and, therefore, pitch." [Law of Variation of Atomic Pitch by Electricity and Magnetism]

"Atoms in chemical combination oscillate with increasing amplitude directly as the temperature, and simultaneously absorb overtones of higher harmonics, producing expansion of volume and diminution of pitch." [Law of Variation of Atomic Pitch by Temperature]
