vapourous

— [W]e ſee that the very aire it ſelfe is never conglaciate nor frozen, nor hardened, conſidering that miſts, fogs and clouds are no congealations, but onely gatherings and thickenings of a moiſt and vapourous aire: for the true aire indeed vvhich hath no vapour at all and is altogether drie, admitteth no ſuch refrigeration as may alter it to that degree and heigth ^([sic]).
