De tabe et phthisi pronunciata

is partly kata physin according to nature, and partly para physin contrary to nature.

VII.
Natural consumption is that in which, according to the natural period, moisture is gradually consumed by native heat throughout the entire course of life, by which the body, failing together, lapses into old age as it becomes colder and drier.

VIII.
That which is contrary to nature arises sometimes from a simple, predominantly dry intemperance, and sometimes from a complex one, namely coupled with dryness, coldness, or heat.

IX.
That which progresses from simple dryness is properly called Marasmus wasting away, which Galen defines as the destruction of a living body due to dryness, for the most part an established offspring of hectic fever that threatens total destruction.

X.
That which has coldness joined to dryness is not inappropriately called old-age disease, familiar both to those aging and to those who contract a disease not unlike old age. It often happens also from fevers transitioning into it due to untimely and immoderate refrigeration. To this is also referred marasmos synkopōdēs fainting wasting.

XI.
That which draws its origin from heat joined to dryness is called "Torrid," induced by very burning, persistent fevers, especially in a drier habit.

XII.
Phthisis, distinguished by a special appellation, is the emaciation of the whole body following upon ulcers of the lungs, with a slow and continuous fever.

XIII.
The causes accelerating phthisis are partly internal and partly external.

XIV.
The internal or proēgoumenai preceding causes are a vicious conformation of the lungs and chest (by which name, diaplasseōs formation, we include both their constriction and their lack of growth), the downward flow of acrid, salty, and eroding catarrhs from the brain: acrid humor ejected from the heart into the lungs: pus enclosed in the capacity of the chest from angina or pleurisy
