solid matter forms in their bladder. But feverishness
of the bowels must be accompanied by feverishness
of the bladder. For when it is abnormally
heated its mouth is inflamed. In this condition it
does not expel the urine, but concocts and heats it
within itself. The finest part is separated off, and
the clearest passes out as urine, while the thickest
and muddiest part forms solid matter, which, though
at first small, grows in course of time. For as it rolls
about in the urine it coalesces with whatever solid
matter forms, and so it grows and hardens. When
the patient makes water, it is forced by the urine to
fall against the mouth of the bladder, and staying
the flow of the urine causes violent pain. So that
boys that suffer from stone rub and pull at their
privy parts, under the impression that there lies the
cause of their making water. Coray's emendation would mean, "the
cause of the
stoppage," an attractive alteration. | That my account is
correct is shown by the fact that sufferers from stone
emit urine that is very clear, as the thickest and
muddiest part of it remains and solidifies. This in
most cases is the cause of stone. Children get stone
also from the milk, if it be unhealthy, too hot and
bilious. For it heats the bowels and the bladder,
so that the urine is heated and affected as I have
described. And my opinion is that we should give
to young children only very diluted wine, which
heats and parches the veins less. Females suffer
less from stone. For their urethra is short and
broad, so that the urine is easily expelled. Nor do
they rub the privy parts as do males, nor handle the
