We see that lightnings and coruscations, which are near at hand, yield no sound. Bacon's Natural History, № 114.
We may learn that sulphureous streams abound in the bowels of the earth, and ferment with minerals, and sometimes take fire with a sudden coruscation and explosion. Newton's Opt.
How heat and moisture mingle in a mass,
Or belch in thunder, or in lightning blaze;
Why nimble coruscations strike the eye,
And bold tornado's bluster in the sky. Garth's Dispensatory.
