, depend much on the quantity secreted by the
kidnies, and the quantity absorbed from it again in the bladder: the kinds
of sediment, as the lateritious, purulent, mucous, or bloody sediments,
depend on other causes. It should be observed, that if the sweating be
increased by the heat of the room, or of the bed-clothes, that a paucity of
turbid urine will continue to be produced, as the absorbents of the bladder
will have their activity increased by their sympathy with the vessels of
the skin, for the purpose of supplying the fluid expended in perspiration.
The pulse becomes strong and full owing to the increased irritability of
the heart and arteries, from the accumulation of sensorial power during
their quiescence, and to the quickness of the return of the blood from the
various glands and capillaries. This increased action of all the secretory
vessels does not occur very suddenly, nor universally at the same time. The
heat seems to begin about the center, and to be diffused from thence
irregularly to the other parts of the system. This may be owing to the
situation of the parts which first became quiescent and caused the
fever-fit, especially when a hardness or tumour about the praecordia can be
felt by the hand; and hence this part, in whatever viscus it is seated,
might be the first to regain its natural or increased irritability.
3. It must be here noted, that, by the increased quantity of heat, and of
the impulse of the blood at the commencement of the hot fit, a great
increase of stimulus is induced, and is now added to the increased
irritability of the system, which was occasioned by its previous
quiescence. This additional stimulus of heat and momentum of the blood
augments the violence of the movements of the arterial and glandular system
in an increasing ratio. These violent exertions still producing more heat
and greater momentum of the moving fluids, till at length the sensoral
power becomes wasted by this great stimulus beneath its natural quantity,
and predisposes the system to a second cold fit.
At length all these unnatural exertions spontaneously subside with the
increased irritability that produced them; and which was itself produced by
the preceding quiescence, in the same manner as the eye, on coming from
darkness into day-light, in a little time ceases to be dazzled and pained,
and gradually recovers its natural degree of irritability.
