THIS Queftion hath no fmall difficulty in it; and I could wish to have more accurate Obfervations on this Head, to determine what Winds then blow in the several Places; or if they return again each Year; for I remember to have read, that in Aquitania, a part of France, there is an anniverfary Wind.

BUT if any thing be faid to this Question, these Particulars feem proper; 1. In our Dog-Days the North Wind blows, which cannot be denied. 2. 'Tis not so constant, nor doth it return every Year; perhaps it may not be felt, because of the frequent blowings of other Winds. 3. It might be faid; the Mountain whereon the Snow begins first to melt, is fituated directly towards Greece; and therefore the first DogWind is carried thither; and the Vapours from the Snow on the reft of the Mountain is carried thither; because they then find an open Paffage that way: but these extemporary Thoughts I fhall lay afide, fo foon as I find better from better Obfervations.

PROPOSITION VI.

Some Winds are proper, and almost perpetual, to fome Place or Tract of the Earth, others inconftant.

THERE are few Places where a Wind blows always; the principal are thefe: viz. 1. Places under the Torrid Zone, especially the Parts of the Pacific and Ethiopic Sea in that Zone have a perpetual Wind from the Eaft, or fome collateral Point, which we called, Prop. 11, a general Wind. And this Wind is not fo much to be termed proper as common, or belonging to many Places; for 'tis by accident that 'tis not felt in all Places; viz. because other Winds blow more ftrongly. The Caufe of it is given in the forecited Place.

2. ON the Shores of the Kingdom of Peru and Parts of Chili, and the adjacent Places on the Sea, LI 2

the

SECT. VI. The Wind is almost perpetually South, or in fome collateral Point to the Weft. It begins at the forty fixth Degree of Latitude, and blows to Panama at the American Ifthmus, and makes the Ships (loaded with Gold and Silver) come from Lima to Panama, in a few Days; tho' it takes a great many Days to return: but in Places remote from the Sea this Wind doth not blow. 'Tis hard to give the cause of this Wind; because the South Land, from which it feems to blow, is not yet known to us; yet I fuppofe there are found therein Mountains continually covered with Snow, from the conftant meltings whereof these Winds blow. But I would not here prepoffefs the Reader's Judgment with my Conjectures. Perhaps the Snows that are found at the Streights of Magellan, all the Year, are the Caufe of this Wind. But yet these Mountains lie from the South eastward, and the Winds blow from a Point declining from the South weftward. Let us then leave this 'till we have a better knowledge of the South Continent.

3. AT the Shores of the Magellanic Land, or del Fuogo, about the Streights of La Maire, there blow almost constant Weft Winds strongly; fo that the Trees decline from a perpendicular to the Eaft. Nor is there any Place where these West Winds blow fo much. But on the other Side of the Streights of La Maire, the South Wind blows on the Shores of the South Land. I can give no other reason for it than the melting of the Snow, and the breaking of the Clouds in the South Land; which extends itself on the Weft Side of that Streight, from South to North. Thefe Things are doubtful, and to be more diligently enquired into.

4. ON the Shore of Malabar, in India, the North and North-Weft Wind blows almoft the whole Year. The Cause is the melting of the Snow on the Mountains of Sarmatia, in Afia, as thofe

I

of

of Imaus, Caucafus, or from the Clouds on other Mountains in Afia that prefs the Air below.

5. ON the Sea, near Guinea, the North-West Wind blows frequently; but further off the NorthEaft Wind blows.

6. HALF way between Japan and Liampo, a Sea-Port Town in China, the Weft Winds blow all the way to Japan, thefe blow there in November and December.

7. AT the Ifland Guoton, not far from the Ifland dos Cavallos, the South Wind is frequent on the Chinese Sea; whilst on the adjacent Seas the North Wind rages.

PROPOSITION VII.

Thofe Winds that blow for fome Hours every Day, in fome Places, at a certain Time of the Year, belong to the periodical or stated Winds.

THEY are found to be twofold; but only in fome Places near the Sea. Some blow from the inland Parts to the Sea; others again from the Sea to the Land: the former is called a Land-Wind, the latter a Sea-Wind.

1. ON the Malabar Shore in the Summer-time, from September to April, the Land-Winds blow from twelve at Night to twelve at Noon, which are Eaft Winds; nor are they fenfible beyond ten Miles on the Sea; and from twelve at Day to twelve at Night the Sea-Wind blows from the Weft, but fo weakly that Ships have little Benefit from it. The former Eaft Winds I fuppofe come partly from the general Wind, and partly from the Clouds on the Mountains of the Gate: but the Cause of the latter is the diffolving of the Clouds by the western Sun; which Clouds were forced together by the Eaft Winds. Thefe are my Conjectures; but in other Months the North Wind rages there, as alfo

L1 3

the

the Eaft, North-Eaft; nor are the gentle Land and Sea-Winds fenfible there, for the frequent Storms.

2. AT the Town of Mafulipatan, on the Shore of Coromandel, the Land-Winds begin to blow on the first Day of June; they laft only fourteen Days, and then it is the Ships go from thence, But these are rather to be referred to the Monfoons; for fo far as I understand from Sailors Accounts, the Land Winds are conftant on those Days; nor do the Sea-Winds come after them.

3. ON the American Shore of New-Spain the Land-Winds blow to the Pacific Sea at twelve at Night; but the Sea-Winds in the Day.

4. IN the Kingdom of Congo, and the Provinces of Lopo Confalvo, the Land-Winds blow from the Evening to the Morning, when the Sea-Winds begin to blow and mitigate the Heat of the Day.

5. AS to the Eaft Winds which blow before and at Sun-rifing, every Day, in all Places, efpecially at Sea, when other Winds blow not, particularly in Brafil where they blow every Day in the Morning, the Caufe is plain. for either they are a Fart of the general Wind, or else the Sun rarifies the grofs Particles of the Air that were condenfed by Night.

6. THE Etefan Winds of the Grecians, or their Chelidonian Winds, come among thefe Quotidian Winds.

7. ON the Shore of Cambaya à Varella, at PuloCatte, the Land and Sea Breezes fucceed one another daily, from the twenty eighth of July to the fourth of August; for then the Monfoons cease, and there is a perfect Calm for a while. The Land Breezes are from the Weft and North-Weft, But the Sea Breezes are from the Eaft, and the collateral Points which turn to the North; and then turn back to the South; when 'tis calm 'till the

Land

Land Breezes come, which are not felt on the Sea above two Miles from the Shore. Thefe Land and Sea Breezes are alfo found at Havanna in America.

PROPOSITION VIII.

The nearer we come to the Equator from the Artic Pole, the northern Winds are the weaker; and beyond the Equator the South Winds are strong, and cold and dry, especially in Chili and Peru.

THE Caufe of both is the fame; because they come from the northern and fouthern Places: yet there are found South Winds in the northern, and North Winds in the fouthern Parts.

PROPOSITION IX.

It appears from what hath been faid, that there are four different kinds of Winds.

1. THE Common, which blow in all Places, and all times; except hindered by others, as the General one.

2. THE proper, or fuch as blow at all times, but only in a certain Place or Tract of the Earth.

3. THOSE which blow in feveral Places, but not at all Times, as the Monfoons, or Quotidian Winds. 4. THOSE which blow neither at all Times, nor in very many Places.

PROPOSITION X.

Some Winds are fudden, and strong, but do not lat long; fuch are Hurricanes, with, and without Lightening; Whirlwinds, Storms from the Water, and from the Air. These are in fome Places anniverfary: and fome are only frequent in certain Places

at Sea.

THE Wind called Prefter; is a ftrong Wind that breaks out with Lightening and Flame.
