verted motions of the cutaneous lymphatics of the
upper part of the body, and at the same time the increased absorption of
the pulmonary absorbents: hence these sweats when profuse relieve the
present fit of asthma. There is no other way to account for sweats
appearing on the upper parts of the body only, but by the fluid having been
absorbed by the lymphatic branch of the lungs, and effused on the skin by
the retrograde movements of the cutaneous lymphatics; which join those of
the lungs before they enter into the venous circulation. For if they were
occasioned, as generally supposed, by the difficulty of the circulation of
the blood through the lungs, the whole skin must be equally affected, both
of the upper and lower parts of the body; for whatever could obstruct the
circulation in the upper part of the venous system, must equally obstruct
it in the lower part of it. See Sect. XXIX. 6. In the convulsive asthma
these sweats do not occur; hence they may be distinguished; and might be
called the hydropic asthma, and the epileptic asthma.

9. _Translatio puris._ Translation of matter from one part of the system to
another can only be explained from its being absorbed by one branch of the
lymphatic system, and deposited in a distant part by the retrograde motions
of another branch; as mentioned Sect. XXIX. 7. 1. It is curious, that these
translations of matter are attended generally, I believe, with cold fits;
for less heat is produced during the retrograde action of this part of the
system, as no secretion in the lymphatic glands of the affected branches
can exist at the same time. Do any ineffectual retrograde motions occasion
the cold fits of agues? The time when the gout of the liver ceases, and the
gout in the foot commences, is attended with a cold fit, as I have observed
in two instances, which is difficult to explain, without supposing the new
vessels, or the matter produced on the inflamed liver, to be absorbed, and
either eliminated by some retrograde motion, or carried to the newly
inflamed part? See Class IV. 1. 2. 15.

10. _Translatio lactis._ Translation of milk to the bowels in puerperal
fevers can only be explained by the milk being absorbed by the pectoral
branch of lymphatics, and carried to the bowels by the retrograde motions
of the intestinal lymphatics or lacteals. See many instances of this in
Sect. XXIX. 7. 4.

11. _Translatio urinae._ Translation of urine. There is a curious case
related in the
