. From this analogy I imagine the pain of the
glans penis is associated with the pain of the sphincter of the bladder;
but that _as soon as the greater pain in a more sensible part is produced;
the lesser one, which occasioned it, ceases_; and that this is one of the
laws of sensitive association. See Sect. XXXV. 2. 1.

A young man had by an accident swallowed a large spoonful or more of
tincture of cantharides; as soon as he began to feel the pain of strangury,
he was advised to drink large quantities of warmish water; to which, as
soon as it could be got, some gum arabic was added. In an hour or two he
drank by intervals of a few minutes about two gallons of water, and
discharged his urine every four or five minutes. A little blood was voided
towards the end, but he suffered no ill consequence.

Solution of fixed alkali supersaturated with carbonic acid. A bougie may be
used to push back a stone into the bladder. See Class I. 1. 3. 10.

3. _Stranguria convulsiva._ The convulsive strangury, like that before
described, is probably occasioned by the torpor or defective action of the
painful part in consequence of the too great expenditure of sensorial power
on the primary link of the associated motions, as no heat or inflammation
attends this violent pain. This kind of strangury recurs by stated periods,
and sometimes arises to so great a degree, that convulsion or temporary
madness terminates each period of it. It affects women oftener than men, is
attended with cold extremities without fever, and is distinguished from the
stone of the bladder by the regularity of its periods, and by the pain
being not increased after making water.

On introducing the catheter sometimes part of the urine will come away and
not the whole, which is difficult to explain; but may arise from the
weakness of the muscular fibres of the bladder; which are not liable
suddenly to contract themselves so far as to exclude the whole of the
urine. In some old people, who have experienced a long retention of urine,
the bladder never regains the power of completely emptying itself; and many
who are beginning to be weak from age can make water a second time, a few
minutes after they supposed they had emptied the bladder.

I have believed this pain to originate from sympathy with some distant
part, as from ascarides in the rectum, or from piles in women; or from
caruncles in the
