aecias does not bring fair weather because it returns upon itself,Alexei Kovalev Tröjor. Hence the saying: ‘Bringing it on himself as Caecias does clouds.’
When they cease,Nicklas Grossmann Tröjor, winds are succeeded by their neighbours in the direction of the movement of the sun. For an effect is most apt to be produced in the neighbourhood of its cause, and the cause of winds moves with the sun.
Contrary winds have either the same or contrary effects. Thus Lips and Caecias, sometimes called Hellespontias, are both rainy gestes and Eurus are dry: the latter being dry at first and rainy afterwards. Meses and Aparctias are coldest and bring most snow. Aparctias,Jonathan Ericsson Tröjor, Thrascias,Air Jordan Retro 5 Męskie, and Argestes bring hail. Notus, Zephyrus, and Eurus are hot. Caecias covers the sky with heavy clouds, Lips with lighter ones. Caecias does this because it returns upon itself and combines the qualities of Boreas and Eurus. By being cold it condenses and gathers the vaporous air, and because it is easterly it carries with it and drives before it a great quantity of such matter. Aparctias, Thrascias,Belstaff Knockhill Jackor, and Argestes bring fair weather for the reason we have explained before. These winds and Meses are most commonly accompanied by lightning. They are cold because they blow from the north,CG Dame Constable Parka, and lightning is due to cold,Marc-Andre Fleury Tröjor, being ejected when the clouds contract. Some of these same bring hail with them for the same reason; namely, that they cause a sudden condensation.
Hurricanes are commonest in autumn, and next in spring: Aparctias, Thrascias, and Argestes give rise to them most. This is because hurricanes are generally formed when some winds are blowing and others fall on them; and these are the winds which are most apt to fall on others that are blowing; the reason for which, too,Ron Francis Tröjor, we have explained before.
The Etesiae veer round: they begin from the north,artie parka, and become for dwellers in the west Thrasciae, Argestae,Pittsburgh Penguins Tröjor, and Zephyrus (for Zephyrus belongs to the north). For dwellers in the east they veer round as far as Apeliotes.
So much for the winds, their origin and nature and the properties common to them all or peculiar to each.

We must go on to discuss earthquakes next, for their cause is akin to our last subject.
The theories that have been put forward up to the present date are three, and their authors three men, Anaxagoras of Clazomenae, and before him Anaximenes of Miletus, and later Democritus of Abdera.
Anaxagoras says that the ether, which naturally moves upwards, is caught in hollows below the earth and so shakes it,Air Jordan Retro 1 Męskie, for though the earth is really all of it equally porous, its surface is clogged up by rain. This implies that part of the whole sphere is ‘above’ and part ‘below’: ‘above’ being the part on which we live, ‘below’ the other.
This theory is perhaps too primitive to require refutation. It is absurd to think of up and down otherwise than as meaning that heavy bodies move to the earth from every quarter, and light ones, such as fire, away from it; especially as we see that, as far as our knowledge of the earth goes,Steven Stamkos Tröjor, the horizon always changes with a chang
