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

High authority
gives the heights of the clouds as follows: lower clouds, 16,000 feet;
upper clouds, 23,000 feet.
As all clouds, from the highest to the lowest, are affected by the
centers as above referred to, it follows that if this "meteoric dust"
follows the earth around, as it would have to do in order to make good
this theory, it would have to travel suspended in the atmosphere above
the upper clouds, or at a height of more than 23,000 feet, or at an
elevation of over four miles!
Now, is it reasonable to believe that dust, however fine, will remain in
the atmosphere at that elevation for over six months?
As a side argument it is suggested that the smoke of the burning woods,
or few years ago in Michigan, caused as peculiar condition of the
atmosphere. This extensive fire was on a day when the area of low
barometer was on a high line of latitude and passing to the eastward.
This naturally took the smoke, which is far lighter than dust, along
with it. It mingled with the muggy condition of an extensive "low," and
produced a yellowness of the atmosphere.
