"Scientific American Supplement, No. 433, April 19, 1884"


This "meteoric dust" they say combined with the atmosphere, followed it
around the earth, and caused the beautiful redness of the sky at morning
and evening. For one, I do not believe dust of any description in the
atmosphere would produce such an effect.
There is nothing luminous, transparent, or delicate about dust. Dust
would not remain in the atmosphere for months, it would settle in a very
short time, and if thick enough in the atmosphere to obstruct the light
of the sun it would be visible, discernible, to the eye, and manifest
on the face of nature. Years ago, before the age of the weather map, we
might have thought that the atmosphere followed the surface of the earth
like the water on a grindstone, but it does not. As already seen, the
wind is from the area of high barometer to that of low, and there are
many of these "low centers."
From the best calculation we can make at present, there would be at
least some six centers on an average between the center of the United
States and the island of Java.
