tion of it also is greater, it
does not stand on the skin in visible drops: add to this, that the
evaporation of it also is greater, from the increased heat of the skin. But
at the decline of the hot fit, as the mouths of the absorbents of the skin
are exposed to the cooler air, or bed-clothes, these vessels sooner lose
their increased activity, and cease to absorb more than their natural
quantity: but the secerning vessels for some time longer, being kept warm
by the circulating blood, continue to pour out an increased quantity of
perspirable matter, which now stands on the skin in large visible drops;
the exhalation of it also being lessened by the greater coolness of the
skin, as well as its absorption by the diminished action of the lymphatics.
See Class I. 1. 2. 3.

The increased secretion of bile and of other fluids poured into the
intestines frequently induce a purging at the decline of the hot fit; for
as the external absorbent vessels have their mouths exposed to the cold
air, as above mentioned, they cease to be excited into unnatural activity
sooner than the secretory vessels, whose mouths are exposed to the warmth
of the blood: now, as the internal absorbents sympathize with the external
ones, these also, which during the hot fit drank up the thinner part of the
bile, or of other secreted fluids, lose their increased activity before the
gland loses its increased activity, at the decline of the hot fit; and the
loose dejections are produced from the same cause, that the increased
perspiration stands on the surface of the skin, from the increased
absorption ceasing sooner than the increased secretion.

The urine during the cold fit is in small quantity and pale, both from a
deficiency of the secretion and a deficiency of the absorption.

During the hot fit it is in its usual quantity, but very high coloured and
turbid, because a greater quantity had been secreted by the increased
action of the kidnies, and also a greater quantity of its more aqueous part
had been absorbed from it in the bladder by the increased action of the
absorbents; and lastly, at the decline of the hot fit it is in large
quantity and less coloured, or turbid, because the absorbent vessels of the
bladder, as observed above, lose their increased action by sympathy with
the cutaneous ones sooner than the secretory vessels of the kidnies lose
their increased activity. Hence the quantity of the sediment, and the
colour of the urine, in fevers
