t constellations and also of what called ‘scattered’ stars (you have only to look to see this clearly). So for these reasons all this matter is continually and ceaselessly collecting there. A proof of the theory is this: In the circle itself the light is stronger in that half where the milky way is divided, Moncler Naiset untuvaliivi and Canada Goose Herr in it the constellations are more numerous and closer to one another than in the other half; which shows that the cause of the light is the motion of the constellations Ralph Lauren Pony Polos and nothing else. For if it is found in the circle in which there are most constellations and at that point in the circle at which they are Naiset Cg Resolute Parka densest and contain the biggest and the most stars, it is natural to suppose that they are the true cause of the affection in question. Timberland Lapset Roll-Top Boots The circle and the constellations in it may be seen in the diagram. The so-called ‘scattered’ stars it is not possible to set down in the same way on the sphere because none of them have an evident permanent position; but if you look up to the sky the point is clear. For in this circle alone are the intervals full of these stars: in the other circles there are obvious gaps. Hence if we accept the cause assigned for the appearance of comets as plausible we must assume that the same kind of thing holds good of the milky way. For the fringe which in the former case is an affection of a single star here forms in the same way in relation to a whole circle. So if we are to define the milky way we may call it ‘a fringe attaching to the greatest circle, and due to the matter secreted’. This, as we said before, explains why there are few comets and why they appear rarely; Ralph Lauren Jackets it is because at Miehet Parajumpers UGO each revolution of the heavens this matter has always been and is always being separated off Moncler Naiset 2017 and gathered into this region.
We have now explained the phenomena that occur in that part of the terrestrial world which is continuous with the motions of the heavens, namely, shooting-stars and the burning flame, comets and the milky way, these being the chief affections that appear in that region.

Let us go on to treat of the region which follows next in order after this and which immediately surrounds the earth. It is the region common to water and air, and the processes attending the formation of water The North Face Naiset kengät above take place in rescue jacka it. We must consider the principles and causes of all these phenomena too as before. The efficient and chief and first cause is the circle in which the sun moves. For the sun as it approaches or recedes, obviously causes dissipation and condensation and so gives rise to generation and destruction. Ralph Lauren Couple Now the earth remains but the moisture surrounding it is made to evaporate by the sun’s rays and the other heat from above, and rises. But when the heat which was raising it leaves it, in part dispersing to the higher region, in part quenched through rising Moncler Miehet untuvaliivi so far into the upper air, then the vapour cools because its heat is gone and because the place is cold, and condenses again and turns from air into water. And after the water has formed it falls down again to the earlinks:
