Hence things that putrefybegin by being moist and end by being dry. For the moist and the drywere their matter, and the operation of the active qualities causedthe dry to be determined by the moist. Destruction supervenes when the determined gets the better of thedetermining by the help...

WE have explained that the qualities that constitute the elementsare four, and that their combinations determine the number of theelements to be four. Two of the qualities, the hot and the cold, are active; two, the dryand the moist, passive. We can satisfy ourselves of this by looking...

Mock suns, and rods too, are due to the causes we have described.A mock sun is caused by the reflection of sight to the sun. Rods areseen when sight reaches the sun under circumstances like those whichwe described, when there are clouds near the sun and sight isreflected from some...

Mock suns and rods are found, as we stated, about sunset andsunrise, not above the sun nor below it, but beside it. They are notfound very close to the sun, nor very far from it, for the sundissolves the cloud if it is near, but if it is far off the reflectioncannot take place, since...

Further, the angle which HM and MImake with HI will always be the same. So there are a number oftriangles on HI and KI equal to the triangles HMI and KMI. Theirperpendiculars will fall on HI at the same point and will be equal.Let O be the point on which they fall. Then O is the centre of...

Draw a line DB outside of the figure and divide it so thatD:B=MH:MK. But MH is greater than MK since the reflection of thecone is over the greater angle (for it subtends the greater angle ofthe Microsoft Office 2010 is so great.
triangle KMH). Therefore D is greater than B. Then add to...

The rainbow can never be a circle nor a segment of a circlegreater than a semicircle. The consideration of the diagram will provethis and the other properties of the rainbow. (See diagram.) Buy Office 2007 you can get much convenience.
Let A be a hemisphere resting on the circle of the...

The appearance of yellow is due to contrast, for the red iswhitened by its juxtaposition with green. We can see this from thefact that the rainbow is purest when the cloud is blackest; and thenthe red shows most yellow. (Yellow in the rainbow comes between redand green.) So the whole of the...

The light of the lampappears as a circle which is not white but purple. It shows thecolours of the rainbow; but because the sight that is reflected is tooweak and the mirror too dark, red is absent. The rainbow that isseen when oars are raised out of the sea involves the same...
