Objection Fourth.-Experience has proved that we have the most rain in nights, and in winter, when, of course, it must be the coldest, as then the sun has the least influence.

Objection Fifth.-There is no vapor arises from the water when the sun has the most influence; for place a looking-glass over a river, when the sun shines with his meridian force, and it will not so much as dim it; but when the sun is gone down, the vapor rises so as to be visible.

Objection Sixth.-If the old theory be true, there would always be the most rain in the tropics, where the sun is vertical, which is not the fact.-[Field Naturalists' Magazine.]

evading as large a part of that tax as they can;
and this may often be accomplished in ways
that are perfectly fair and legal. An excise
duty exists at present of 3d.‡ per pound upon

that much of the paper which is employed is
made extremely thin, in order that the weight
of a given number of sheets may be as small as
possible. Soon after the first imposition of the
tax upon windows, which depended upon their
number, and not upon their size, new-built
houses began to have fewer windows and of a
larger size than before. Staircases were light-
ed by extremely long windows, illuminating
three or four flights of stairs. When the tax
was increased, and the size of windows charged
as single was limited, then still greater care
was taken to have as few windows as possible,
and internal lights became frequent. These
internal lights in their turn became the subject
of taxation; but it was easy to evade the disco-
