he vertigo occasioned by swinging; which has lately been introduced
into practice by Dr. Smith, (Essay on Pulmonary Consumption), who observed
that by swinging the hectic pulse became slower, which is explained in
Class IV. 2. 1. 10. The usual way of reciprocating swinging, like the
oscillations of a pendulum, produces a degree of vertigo in those, who are
unused to it; but to give it greater effect, the patient should be placed
in a chair suspended from the ceiling by two parallel cords in contact with
each other, the chair should then be forcibly revolved 20 or 40 times one
way, and suffered to return spontaneously; which induces a degree of
sickness in most adult people, and is well worthy an exact and pertinacious
trial, for an hour or two, three or four times a day for a month.

The common means of promoting absorption in ulcers, and of thickening the
matter in consequence, by taking the bark and opium internally, or by
metallic salts, as of mercury, steel, zinc, and copper, in small
quantities, have been repeatedly used in pulmonary consumption; and may
have relieved some of the symptoms. As mercury cures venereal ulcers, and
as pulmonary ulcers resemble them in their not having a disposition to
heal, and in their tendency to enlarge themselves, there were hopes, from
analogy, that it might have succeeded. Would a solution of gold in aqua
regia be worth trying? When vinegar is applied to the lips, it renders them
instantly pale, by promoting the venous absorption; if the whole skin was
moistened with warmish vinegar, would this promote venous absorption in the
lungs by their sympathy with the skin? The very abstemious diet on milk and
vegetables alone is frequently injurious. Flesh-meat once a day, with small
wine and water, or small beer, is preferable. Half a grain of opium twice a
day, or a grain, I believe to be of great use at the commencement of the
disease, as appears from the subsequent case.

Miss ----, a delicate young lady, of a consumptive family, when she was
about eighteen, had frequent cough, with quick pulse, a pain of her side,
and the general appearances of a beginning consumption. She took about five
drops of laudanum twice a day in a saline draught, which was increased
gradually to ten. In a few weeks she recovered, was afterwards married,
bore three or four children, and then became consumptive and died.
