of health, but crude and unconcocted evacuations,
which change into bad abscessions, denote absence
of crisis, pain, prolonged illness, death, or a return
of the same symptoms. But it is by a consideration
of other signs that one must decide which of these
results will be most likely. Declare the past,
diagnose the present, foretell the future ; practise
these acts. As to diseases, make a habit of two
things--to help, or at least to do no harm. The
art has three factors, the disease, the patient, the
physician. The physician is the servant of the art.
The patient must co-operate with the physician in
combating the disease.
XII. Pains about the head and neck, and heaviness
combined with pain, occur both without and with
fever. Sufferers from phrenitis have convulsions, and
eject verdigris-coloured vomit ; some die very quickly.
But in ardent and the other fevers, those with pain in
the neck, heaviness of the temples, dimness of sight,
and painless tension of the hypochondrium, bleed
from the nose ; those with a general heaviness of the
head, cardialgia, and nausea, vomit afterwards bile and
phlegm. Children for the most part in such cases
suffer chiefly from the convulsions. Women have
both these symptoms and pains in the womb. Older
people, and those whose natural heat is failing, have
paralysis or raving or blindness.
XIII. In Thasos a little before and at the season
of Arcturus many violent rains with northerly winds.
