A small flake.

The first flake or flakelet that reached me was a mere white speck that came idly circling and eddying to the ground.

As regards the relative speed of the meteor as seen by observers on the Earth, since this, as was just now remarked, is precisely that with which the tempest of celestial missiles originally propelled the meteor, as a dust-flake in its wake, from some revolving masses of the ring, if we suppose this speed relative to the earth-ring (whether directed from the "quite" or from the "goal" of the Earh's way, or from anywhere between them), to have been just suitable (because that is a condition supposed to subsist among the generality of now occurring meteors), to launch the flakelet into space on some very long elliptic, nearly parabolic orbit, it is evident that on reappearing, after describing an orbit-circuit of such length compass, as a meteor directed from just the readiant-point which the celestial volley's dust-scud first gave it, whether the radiant-pint be near or far from the apex of the Earh's way, the accompanying apparent meteor-speed must necessarility be the theoretical parabolic-pathed meteor-speed for a radiant-point of the observed apex-elongation.
The hardened layer by induction hardening shows nubby and surface flaking, the length of the flakelet is 5-10 mm, the depth is 0.35–0.55 mm, two sides of the hollow slopes from the bottom to the surface.
