it has just been exposed to the influence of
the air in its passage through the extremities of the pulmonary artery; it
is frothy, from the admixture of air with it in the bronchia. The patients
frequently vomit at the same time from the disagreeable titillation of
blood about the fauces; and are thence liable to believe, that the blood is
rejected from the stomach.

Sometimes an haemoptoe for several successive days returns in gouty persons
without danger, and seems to supply the place of the gouty paroxysms. Is
not the liver always diseased previous to the haemoptoe, as in several
other haemorrhages? See Class I. 2. 1. 9.

M. M. Venesection, a purge, a blister, diluents, torpentia; and afterwards
sorbentia, as the bark, the acid of vitriol, and opium. An emetic is said
to stop a pulmonary haemorrhage, which it may effect, as sickness decreases
the circulation, as is very evident in the great sickness sometimes
produced by too large a dose of digitalis purpurea.

Dr. Rush says, a table spoonful or two of common salt is successful in
haemoptoe; this may be owing to its stimulating the absorbent systems, both
the lymphatic, and the venous. Should the patient respire air with less
oxygen? or be made sick by whirling round in a chair suspended by a rope?
One immersion in cold water, or a sudden sprinkling all over with cold
water, would probably stop a pulmonary haemorrhage. See Sect. XXVII. 1.

5. _Haemorrhagia narium._ _Epistaxis_. Bleeding at the nose in elderly
subjects most frequently attends those, whose livers are enlarged or
inflamed by the too frequent use of fermented liquors.

In boys it occurs perhaps simply from redundancy of blood; and in young
girls sometimes precedes the approach of the catamenia; and then it shews a
disposition contrary to chlorosis; which arises from a deficiency of red
blood.

M. M. It is stopped by plunging the head into cold water, with powdered
salt hastily dissolved in it; or sometimes by lint strewed over with wheat
flour put up the nostrils; or by a solution of steel in brandy applied to
the vessel by means of lint. The cure in other respects as in haemoptoe;
when the bleeding recurs at certain periods, after venesection, and
evacuation by calomel, and a blister, the bark and steel must be given, as
in intermittent fevers. See Section XXVII. 1.
