LIBER II · CAPUT 42
OF UNCERTAIN STATES OF THE WEATHER
Latine · Mayhoff 1906
Extra has causas non negaverim exsistere imbres ventosque, quoniam umidam a terra, alias vero propter vaporem fumidam exhalari caliginem certum est nubesque liquore egresso in sublime aut ex aëre coacto in liquorem gigni. densitas earum corpusque haut dubio coniectatur argumento, cum solem obumbrent, perspicuum alias etiam urinantibus in quamlibet profundam aquarum altitudinem.
English · Bostock & Riley 1855–57
But I would not deny, that there may exist showers and winds, independent of these causes, since it is certain that an exhalation proceeds from the earth, which is sometimes moist, and at other times, in consequence of the vapours, like dense smoke; and also, that clouds are formed, either from the fluid rising up on high, or from the air being compressed into a fluid. Their density and their substance is very clearly proved from their intercepting the sun’s rays, which are visible by divers, even in the deepest waters.
