Now it is universally agreed, that the Sea, is sooner heated by the Sun than the Land: and on Account of the marine Acid exhaled,[70] is also less cold,[71] during that Season, in the same Latitude. In Spring, therefore, the great Atlantic or Western Ocean, being _less_ cold than England, Holland, and Eastwards; the Air pendent over the most extensive Tract of _dry and cool Land_ in the World, rushes Westwards to supply the Equilibrium of _warm light_ Air rising upwards, and causing a temporary mediocèanal Accumulation: which (altho’ the specific Gravity of the cold Air is greater) must produce an actual Deficiency in the aggregate Weight of the Atmosphere over England and Holland: consequently the Barometer falls. Again: the West Winds which blow at other Seasons; if, in Winter; are not frequent, except about Noon after frosty Nights which have equalized the Air for the Transmission of vigorous Sunshine: and shoud be looked upon as (what they are really observed to be) _low_ partial Sea-Breezes, or +eddy+ _Currents_, insinuating themselves near the Surface, and setting Eastwards frequently against the upper and more general Winds; and therefore produce a temporary Accumulation. If, in Summer; the Supply of cool Air to the heated Land, being made not only from the _Northern Ocean_, and lofty _Mediterrànean Mountains_; but also from the _Atlantic Breezes_; the latter, tho’ _moist and temperate_, must also tend towards an Accumulation of the Atmosphere over England and Holland: and therefore the Barometer rises. CHAPTER XXXXVIII. [Sidenote: Facts and Observations tending to confirm the Doctrine of Accumulation and depression.] Section 260. Before the Subject of mediocèanal Accumulation and Depression of Air, is wholly quitted; it may be well mention and compare a few Facts and Observations, which will elucidate the Doctrine; and in their Turn, receive Light from it. 261. If, in the Middle of a _hot sunny_ Day, Vapours lighter than the Air, were to rise from the Ocean, (which they will continue to do, in hollow Vesicles or Bladders, till the Expansion breaks the Bubble, at which Time the Water woud fall to the Earth, if not drank up by the Attraction of _dry_ Spunges of Air;) there woud be a constant Wind blowing from _Land to Sea_, to fill up the Chasm: but at such Time, the Land is more heated than the Sea: therefore hot Air and Vapour arise from both; and the Breeze, on the contrary, blows from _Sea to Land_; consequently if the Vacuities were not _continually_ supplied from the etherial Regions, and from the Ocean, all Animals woud actually die, for Want of Air, as in a _hot close_ Room. Such Supply is therefore constantly made, by Depression of the Atmosphere, and Absorption of the Water.
