CHAP. IX. Of Diseases of Composition.
THE last kind of Organick Diseases are Synthetical, * 1.1 common∣ly called Diseases of Composition; but although Avicen doth account all Organick Diseases, Diseases of composition, yet in this place we do not, we only take them for a peculiar kind of Orga∣nick Diseases.
Since that two things are to be considered in Diseases of compo∣sition, situation and connexion; * 1.2 Diseases of composition are of two kinds, the one is when the parts do change their situation, * 1.3 which is called a Disease of place: The other is when they are not knit together as they ought, but they are separated which ought to be joyned together, and the contrary, as when the eyebrowes grow together, which are called Diseases of connexion or vicinity, others call them Diseases of consent, society, colle, iate.
The most common Disease in place, is a loosing of a joynt, * 1.4 the Greeks call it Exarthrosis, when the joynts or heads of the bones go out of their hollow places or cavities. Yet other parts besides the bones go out of their places, which happeneth in ruptures, when the paunch or guts fall down into the Cods, or when by great wounds the guts come forth: also in the falling out of the womb, or of an eye.
Another kinde of Disease of composition is, when the parts are separated, that ought to be joyned together; which happeneth if the bonds by whose intervene they are linked together are loosened, made longer or broken, which happeneth sometimes in the womb and other parts of the body; or it happens if those are joyned toge∣ther, that should be parted a sunder; as when one is tongue-tyed, or the eye-lids grow together, or two fingers grow together, or the fundament be closed.
