  This is a translation from Latin of 'De novo oscillationum genere', which was
motivated by Krafft's accidental observation of a suspended clock setting
itself in constant motion as a pendulum. This publication, in turn, motivated
Euler to write 'De novo genere oscillationum', in which Euler derived for the
first time, the differential equation for the (undamped) simple harmonic
oscillator under harmonic excitation.
