the urine, and alvine discharges, and sweats, according as they appear
along with favorable or unfavorable symptoms, indicate diseases of
a short or long duration.
Old persons endure fasting most easily; next, adults; young persons
not nearly so well; and most especially infants, and of them such
as are of a particularly lively spirit.
Growing bodies have the most innate heat; they therefore require
the most food, for otherwise their bodies are wasted. In old persons
the heat is feeble, and therefore they require little fuel, as it
were, to the flame, for it would be extinguished by much. On this
account, also, fevers in old persons are not equally acute, because
their bodies are cold.
In winter and spring the bowels are naturally the hottest, and
the sleep most prolonged; at these seasons, then, the most sustenance
is to be administered; for as the belly has then most innate heat,
it stands in need of most food. The well-known facts with regard to

We must purge and move such humors as are concocted, not such

The evacuations are to be judged of not by their quantity,
