The Reason why this morbid Matter is not long fixed in a Place, but
is apt to wander from one Joint to another, I take to be this: These
saline volatile Particles, when their intestine Motions are increased,
are very easily dissipated, either through the Pores of the Skin in
sensible Transpiration and Sweat, or by insensible Perspiration, and
so the Pain ceases; other Glands, whose Pores are more open to receive
this acrid volatile Matter, are for the like Reasons infected, the same
Tragedy repeated, and the Particles in like manner dissipated. This is
the Reason why the Pains in the Gout are not fixed and permanent, but
rather wandring and uncertain, the morbid Particles being attenuated,
and pushing to get forth by the Methods now mentioned, vellicate the
Nerves in various Directions. It may be further considered, that when
by the smallness of the Pores or glandulous Vessels, or any other
Disposition, the morbifick Matter cannot be separated from them in
sufficient Quantity, and the Secretion once begun is stopped, it
recurs to other Glands of the same kind, and thus the morbid Matter is
suddenly translated from one Joint to another, and from one Sett of
Glands to others, so as to produce this Effect.
