a meteor produced in this manner: When the vapours are become considerably condensed, yet not so far as to be liquefied, or dissolved into water; then, by a special degree of coldness in the upper region of the air, the particles of the condensed vapour are changed into ice; several of which adhering together, form little fleeces of a white substance, somewhat heavier than the air; and therefore descend in a slow and gentle manner through it; being subject, by reason of its lightness, to be driven about by the various motions of the air and wind; and is what, when arrived to the surface of the earth, we call snow.

Snow fructifies the ground; for instance, by guarding the corn or other vegetables from the intenser cold of the air, especially the cold piercing winds.
