rly Organized.
Everything merges away into everything else, but proportionately to its
complexity, if unified, a thing seems strong, real, and distinct: so, in
aesthetics, it is recognized that diversity in unity is higher beauty,
or approximation to Beauty, than is simpler unity; so the logicians feel
that agreement of diverse data constitute greater convincingness, or
strength, than that of mere parallel instances: so to Herbert Spencer
the more highly differentiated and integrated is the more fully evolved.
Our opponents hold out for mundane origin of all black rains. Our method
will be the presenting of diverse phenomena in agreement with the notion
of some other origin. We take up not only black rains but black rains
and their accompanying phenomena.

A correspondent to _Knowledge_, 5-190, writes of a black rain that fell
in the Clyde Valley, March 1, 1884: of another black rain that fell two
days later. According to the correspondent, a black rain had fallen in
the Clyde Valley, March 20, 1828: then again March 22, 1828. According
to _Nature_, 9-43, a black rain fell at Marlsford, England, Sept. 4,
1873; more than twenty-four hours later another black rain fell in the
same small town.

The black rains of Slains:

According to Rev. James Rust (_Scottish Showers_):

A black rain at Slains, Jan. 14, 1862--another at Carluke, 140 miles
from Slains, May 1, 1862--at Slains, May 20, 1862--Slains, Oct. 28,
1863.

But after two of these showers, vast quantities of a substance described
sometimes as "pumice stone," but sometimes as "slag," were washed upon
the sea coast near Slains. A chemist's opinion is given that this
substance was slag: that it was not a volcanic product: slag from
smelting works. We now have, for black rains, a concomitant that is
irreconcilable with origin from factory chimneys. Whatever it may have
been the quantity of this substance was so enormous that, in Mr. Rust's
opinion, to have produced so much of it would have required the united
output of all the smelting works in the world. If slag it were, we
accept that an artificial product has, in enormous quantities, fallen
from the sky. If you don't think that such occurrences are damned by
Science, read _Scottish Showers_ and see how impossible it was for the
author to have this matter taken up by the scientific world.

The first and second rains corresponded, in time, with ordinary
ebullitions of Vesuvius.

The third and fourth, according
