both in a reciprocating and in a rotatory swing, without any apparent
absorption of matter; in both these swings he expressed pleasure, and did
not appear to be vertiginous.

Mr. I. had laboured some months under a vomica after a peripneumony, he was
at length taken with a catarrh, which was in some degree endemic in March
1795, which occasioned him to sneeze much, during which a copious
haemorrhage from the lungs occurred, and he spit up at the same time half a
pint of very fetid matter, and recovered. Hence errhines may be
occasionally used with advantage.

4. _Empyema._ When the matter from an abscess in the lungs finds its way
into the cavity of the chest, it is called an empyema. A servant man, after
a violent peripneumony, was seized with symptoms of empyema, and it was
determined, after some time, to perform the operation; this was explained
to him, and the usual means were employed by his friends to encourage him,
"by advising him not to be afraid." By which good advice he conceived so
much fear, that he ran away early next morning, and returned in about a
week quite well. Did the great fear promote the absorption of the matter,
like the sickness occasioned by digitalis? Fear renders the external skin
pale; by this continued decrease of the action of the absorbents of the
skin might not those of the lungs be excited into greater activity? and
thus produce increased pulmonary absorption by reverse sympathy, as it
produces pale urine, and even stools, by direct sympathy?

M.M. Digitalis?

5. _Febris Mesenterica._ Fever from matter formed in the mesentery is
probably more frequent than is suspected. It commences with pain in the
bowels, with irritated sensitive fever; and continues many weeks, and even
months, requiring occasional venesection, and mild cathartics; till at
length the continuance of the pyrexia, or inflammatory fever, destroys the
patient. This is an affection of the lymphatic glands, and properly belongs
to scrophula; but as the matter is not exposed to the air, no hectic fever,
properly so called, is induced.

6. _Febris a pure aerato._ Fever from aerated matter. A great collection of
matter often continues a long time, and is sometimes totally absorbed, even
from venereal buboes, without producing any disorder in the arterial
system. At length, if it becomes putrid by its delay, and one part of t
