Transaction of the College of Physicians at Philadelphia,
Vol. I. p. 96. of a girl, who labouring under an iscuria vomited her urine
for many months; which could not be distinguished from that which was at
other times drawn off by the catheter. After having taken much opium, she
seems at length to have formed gravel, some of which was frequently brought
up by vomiting. Dr. Senter ascribes this to the retrograde motions of the
lymphatics of the stomach, and the increased ones of those of the bladder,
and refers to those of Sect. XXIX. of this work; which section was first
published in 1780; and to Macquire's Dictionary of Chemistry, Art. Urine.

The patient above described sometimes had a discharge of urine by the
navel, and at other times by the rectum, and sometimes by urinous sweats.

SPECIES.

1. _Capillarium motus retrogressus._ In microscopic experiments it is usual
to see globules of blood regurgitate from the capillary vessels again and
again, before they pass through them; and not only the mouths of the veins,
which arise from these capillaries, are frequently seen by microscopes to
regurgitate some particles of blood during the struggles of the animal; but
a retrograde motion of the blood in the veins of these animals, from the
very heart to the extremities of the limbs, is observable by intervals
during the distresses of the dying creature. Haller, Elem. Phys. T. i. p.
216. See Section XXIX. 3. 8.

2. _Palpitatio cordis._ May not the ineffectual and weak unequal motions of
the heart in hysteric cases be ascribed to the retrograde motions of it,
which continue for a short time, or terminate in syncope? See Class IV. 3.
1. 6.

3. _Anhelatio spasmodica._ In some asthmas may not the difficulty of
respiration arise from the inverted action of the finer branches of the
bronchia, or of the pulmonary artery or vein, like those of the capillaries
above described in No. 1. of this genus?
