evacuated, and
continued all that time his usual potations: excepting at first, the
medicine operated only by urine, and did not appear considerably to weaken
him--The last time he took it, it had no effect; and a few weeks afterwards
he vomited a great quantity of blood, and expired.

QUERIES.

1. As the first six of these patients had a due discharge of urine, and of
the natural colour, was not the feat of the disease confined to some part
of the thorax, and the swelling of the legs rather a symptom of the
obstructed circulation of the blood, than of a paralysis of the cellular
lymphatics of those parts?

2. When the original disease is a general anasarca, do not the cutaneous
lymphatics always become paralytic at the same time with the cellular ones,
by their greater sympathy with each other? and hence the paucity of urine,
and the great thirst, distinguish this kind of dropsy?

3. In the anasarca of the lungs, when the disease is not very great, though
the patients have considerable difficulty of breathing at their first lying
down, yet after a minute or two their breath becomes easy again; and the
same occurs at their first rising. Is not this owing to the time necessary
for the fluid in the cells of the lungs to change its place, so as the
least to incommode respiration in the new attitude?

4. In the dropsy of the pericardium does not the patient bear the
horizontal or perpendicular attitude with equal ease? Does this
circumstance distinguish the dropsy of the pericardium from that of the
lungs and of the thorax?

5. Do the universal sweats distinguish the dropsy of the pericardium, or of
the thorax? and those, which cover the upper parts of the body only, the
anasarca of the lungs?

6. When in the dropsy of the thorax, the patient endeavours to lie down,
does not the extravasated fluid compress the upper parts of the bronchia,
and totally preclude the access of air to every part of the lungs; whilst
in the perpendicular attitude the inferior parts of the lungs only are
compressed? Does not something similar to this occur in the anasarca of the
lungs, when the disease is very great, and thus prevent those patients also
from lying down?

7. As a principal branch of the fourth cervical nerve of the left side,
after having joined a branch of the third and of the second cervical
nerves, descending between the subclavian vein and artery, is received in a
groove formed for it in the pericardium, and is obliged
