(as Aquapend. Fabricius ab Aquapendente l. c. speaks) made in the last vertebrae of the loins, from the production of the hollow vein vena cava and the great artery aorta from there to the anus. See Minderer. in medical military ch. 7. and D. Joh. Agricolam, Small Surgery tract. 5. and others.

They call the symptoms of these, namely the Open ones, or the immoderate profusion of hemorrhoids, the blood-flow downward / the golden vein blood-flow. But the suppressed, or blind ones, the obstruction / or the swelling of the Gold-Vein. See Magir. Patholog. lib. 2. sect. 4. cap. 16. p.m. 308.

I.

Having thus perceived the Onomatology, let us gird ourselves for Pragmatology the study of the thing itself, or the thing itself: where, after having laid aside the general Definition of Hemorrhoids, sought from that known difference by which they are separated into healthy and unhealthy; as also that by which some include both kinds in one definition: we shall propose a distinct description of those famous Symptoms only, lest the Definition be ignored, and the thing itself, concerning which the discourse is, be ignored; as the golden river of eloquence Cicero, Cicero, lib. 1. on Duties, opportunely warns.

II. Therefore, defining both Hemorrhoids separately, OPEN are: An immoderate Flow of Blood from the vessels of the anus, joined with the prostration of strength, proceeded from an intense irritation of the expulsive faculty, and a preternatural opening of those vessels.

III. Let this be the ὁρισμὸς definition of BLIND ONES: They are a tumor of the vessels of the anus, arisen from the influx of thick blood flowing together, joined with immense and exquisite pain.

IV. The Definitions having been given, one must proceed to a succinct ἀνάλυσιν analysis of them. Since, however, all perfect definitions of Accidents, according to the tenets of Philosophers, consist of a triple kind of causes, Form or proximate Genus, Matter or subject
