not to be reached by plugs up the nostrils, and the
sensibility of her fauces was such that nothing could be born behind the
uvula. After repeated venesection, and other common applications, she was
directed to immerse her whole head into a pail of water, which was made
colder by the addition of several handfuls of salt, and the haemorrhage
immediately ceased, and returned no more; but her pulse continued hard, and
she was necessitated to lose blood from the arm on the succeeding day.

Query, might not the cold bath instantly stop haemorrhages from the lungs in
inflammatory cases?--for the shortness of breath of those, who go suddenly
into cold water, is not owing to the accumulation of blood in the lungs,
but to the quiescence of the pulmonary capillaries from association, as
explained in Section XXXII. 3. 2.

II. The other kind of haemorrhage is known from its being attended with a
weak pulse, and other symptoms of general debility, and very frequently
occurs in those, who have diseased livers, owing to intemperance in the use
of fermented liquors. These constitutions are shewn to be liable to
paralysis of the lymphatic absorbents, producing the various kinds of
dropsies in Section XXIX. 5. Now if any branch of the venous system loses
its power of absorption, the part swells, and at length bursts and
discharges the blood, which the capillaries or other glands circulate
through them.

It sometimes happens that the large external veins of the legs burst, and
effuse their blood; but this occurs most frequently in the veins of the
intestines, as the vena portarum is liable to suffer from a schirrus of the
liver opposing the progression of the blood, which is absorbed from the
intestines. Hence the piles are a symptom of hepatic obstruction, and hence
the copious discharges downwards or upwards of a black material, which has
been called melancholia, or black bile; but is no other than the blood,
which is probably discharged from the veins of the intestines.

J.F. Meckel, in his Experimenta de Finibus Vasorum, published at Berlin,
1772, mentions his discovery of a communication of a lymphatic vessel with
the gastric branch of the vena portarum. It is possible, that when the
motion of the lymphatic becomes retrograde in some diseases, that blood may
obtain a passage into it, where it anastomoses with the vein, and thus be
poured into the intestines. A discharge of blood with the urine sometimes
attends diabetes, and may ha
