e skin a fluid, which is said to be viscid, and which adheres
in drops.

A few days ago I saw a young man of delicate constitution in what was
called a fit of the asthma; he had about two months before had a
peripneumony, and had been ever since subject to difficult respiration on
exertion, with occasional palpitation of his heart. He was now seized about
eight at night after some exertion of mind in his business with cold
extremities, and difficulty of breathing. He gradually became worse, and in
about half an hour, the palpitation of his heart and difficult respiration
were very alarming; his whole skin was cold and pale, yet he did not
shudder as in cold paroxysm of fever; his tongue from the point to the
middle became as cold as his other extremities, with cold breath. He seemed
to be in the act of dying, except that his pulse continued equal in time,
though very quick. He lost three ounces of blood, and took ten drops of
laudanum with musk and salt of hartshorn, and recovered in an hour or two
without any cold sweat.

There being no cold sweat seems to indicate, that there was no accumulation
of serous fluid in the lungs; and that their inactivity, and the coldness
of the breath, was owing to the sympathy of the air-cells with some distant
part. There was no shuddering produced, because the lungs are not sensible
to heat and cold; as any one may observe by going from a warm room into a
frosty air, and the contrary. So the steam of hot tea, which scalds the
mouth, does not affect the lungs with the sensation of heat. I was induced
to believe, that the whole cold fit might be owing to suppuration in some
part of the chest; as the general difficulty of breathing seemed to be
increased after a few days with pulse of 120, and other signs of empyema.
Does the cold sweat, and the occurrence of the fits of asthma after sleep,
distinguish the humoral asthma from the cold paroxysm of intermittents, or
which attends suppuration, or which precedes inflammation?--I heard a few
weeks afterwards, that he spit up much matter at the time he died.

of the bladder become inverted by their consent with those of the skin;
which are become torpid by their reverse sympathy with the painful ideas of
fear, as in Sect. XVI. 8. 1. whence there is a great discharge of pale
urine, as in hysteric diseases.

The same happens from anxiety, where the painful suspense is co
