on the vena cava, when it is much enlarged.

M. M. Vitriolic acid, opium, steel, bark. Sponge bound on the part. Steel
dissolved in spirit of wine externally. Flour.

6. _Haemorrhois cruenta._ In the bleeding piles the capillary vessels of
the rectum become distended and painful from the defect of the venous
absorption of the part, and at length burst; or the mucous glands are so
dilated as to give a passage to the blood; it is said to observe lunar
periods.

M. M. Venesection, poultices, cathartics, spice, cold bath, and sorbentia.
External compression by applying lint, sponge, or cotton. Internal
compression by applying a bit of candle smeared with mercurial ointment.
Strangulate the tumid piles with a silk string. Cut them off. See Class I.

Mrs. ---- had for twelve or fifteen years, at intervals of a year or less,
a bleeding from the rectum without pain; which however stopped
spontaneously after she became weakened, or by the use of injections of
brandy and water. Lately the bleeding continued above two months, in the
quantity of many ounces a day, till she became pale and feeble to an
alarming degree. Injections of solutions of lead, of bark and salt of
steel, and of turpentine, with some internal astringents, and opiates, were
used in vain. An injection of the smoke of tobacco, with ten grains of
opium mixed with the tobacco, was used, but without effect the two first
times on account of the imperfection of the machine; on the third time it
produced great sickness, and vertigo, and nearly a fainting fit; from which
time the blood entirely stopped. Was this owing to a fungous excrescence in
the rectum; or to a blood-vessel being burst from the difficulty of the
blood passing through the vena porta from some hepatic obstruction, and
which had continued to bleed so long? Was it stopped at last by the
fainting fit? or by the stimulus of the tobacco?

7. _Haemorrhagia renum._ Haemorrhage from the kidnies, when attended with
no pain, is owing to defect of venous absorption in the kidney. When
attended with pain on motion, it is owing to a bit of gravel in the ureter
or pelvis of the kidney; which is a much more frequent disease than the
former. See Sect. XXVII. 1.

M. M. 1. Venesection in small quantity, calomel, bark, steel, an opiate;
cold immersion up to the navel, the upper part of the body being kept
cloathed. Neville-Holt water. 2. Alcalized water aerated. Much diluent
liquids. Cool dress. Cool bed
