system, as shewn in No. 3. 2. of this Section. Hence a deficiency of
all the secretions succeeds, and as animal heat is produced in proportion
to the quantity of those secretions, the coldness of the skin is the first
circumstance, which is attended to. Dr. Martin asserts, that some parts of
his body were warmer than natural in the cold fit of fever; but it is
certain, that those, which are uncovered, as the fingers, and nose, and
ears, are much colder to the touch, and paler in appearance. It is
possible, that his experiments were made at the beginning of the subsequent
hot fits; which commence with partial distributions of heat, owing to some
parts of the body regaining their natural irritability sooner than others.

From the quiescence of the anastomosing capillaries a paleness of the skin
succeeds, and a less secretion of the perspirable matter; from the
quiescence of the pulmonary capillaries a difficulty of respiration arises;
and from the quiescence of the other glands less bile, less gastric and
pancreatic juice, are secreted into the stomach and intestines, and less
mucus and saliva are poured into the mouth; whence arises the dry tongue,
costiveness, dry ulcers, and paucity of urine. From the quiescence of the
absorbent system arises the great thirst, as less moisture is absorbed from
the atmosphere. The absorption from the atmosphere was observed by Dr.
Lyster to amount to eighteen ounces in one night, above what he had at the
same time insensibly perspired. See Langrish. On the same account the urine
is pale, though in small quantity, for the thinner part is not absorbed
from it; and when repeated ague-fits continue long, the legs swell from the
diminished absorption of the cellular absorbents.

From the quiescence of the intestinal canal a loss of appetite and
flatulencies proceed. From the partial quiescence of the glandular viscera
a swelling and tension about the praecordia becomes sensible to the touch;
which is occasioned by the delay of the fluids from the defect of venous or
lymphatic absorption. The pain of the forehead, and of the limbs, and of
the small of the back, arises from the quiescence of the membranous fascia,
or muscles of those parts, in the same manner as the skin becomes painful,
when the vessels, of which it is composed, become quiescent from cold. The
trembling in consequence of the pain of coldness, the restlessness, and the
yawning, and stretching of the limbs, together with the shu
