sus._ There have been instances of bougies
being carried up the urethra into the bladder most probably by an inverted
motion of this canal; for which some have undergone an operation similar to
that for the extraction of a stone. A case is related in some medical
publication, in which a catgut bougie was carried into the bladder, and
after remaining many weeks, was voided piece-meal in a semi-dissolved
state. Another case is related of a French officer, who used a leaden
bougie; which at length found its way into the bladder, and was, by
injecting crude mercury, amalgamated and voided.

In the same manner the infection from a simple gonorrhoea is probably
carried further along the course of the urethra; and small stones
frequently descend some way into the urethra, and are again carried up into
the bladder by the inverted action of this canal.

3. _Ductus choledochi motus retrogressus._ The concretions of bile, called
gall-stones, frequently enter the bile-duct, and give violent pain for some
hours; and return again into the gall-bladder, by the retrograde action of
this duct. May not oil be carried up this duct, when a gall-stone gives
great pain, by its retrograde spasmodic action? See Class I. 1. 3. 8.
