Artic. 1. Of the Originall of Winds.
ARistot. 2. Meteor. c. 4. saith, That the Sun is the cause of the winds, by drawing up the moysture that is upon the surface of the Earth, and by heating, doth dry the Earth it self. Lydiat likes not this opinion; For the Earth moystned being dryed, affords but little matter for winds. For the Earth drinks in no more rain than may quench its thirst, and which it may change into a dry nature, from whence comes no Exhalation of the same allowance, much goes to rain, which is no small part of it. What then shall be left for the vast winds? wherefore, inward heat is pleaded for. And truly, in Winter the Earth sends forth a smoky exhalation. In the Southern parts, Winds arise from Snow; A breath riseth from Lakes and standing Pools; and storms from the Sea, though it be calm: whence is this, but that the Earth breathes out vapours, which break forth through the depth of waters. The Chymical Instrument will shew this, which they use for bellowes, Sennert. l. 4. Epitom. c. 3. A Globe is made of Copper, that it may be fill'd with water, and then shut, a pipe with a small hole is made of one side, the Glob fill'd with water is set to the fire, and the pipe for bellowes is set to another. As the Globe growes hot, and the water rarifies, the Ayr continually breathes forth, and serves for bellows till all the water be consumed. Winds are then bred, when heat burns the moyst Earth. The Sun by drying openeth the pores, and the Ayr helps by its motion. If it rise from the Sea, the Sea at firs•• calm making a muttring noise, signifies that an exhalation that is matter for wind, is already then bred in the bowels of it; some fishes sport, some fasten themselves to rocks: then the Sea swelling a little, shewes that the exhalation newly bred, seeks a passage forth; then when it fails, it shews it is come to the superficies, but in small quantity; then the blasts breaking forth with all their force, lift up the waves before them, and cause Winds and Tempests.
