It is this: Indian nard, poppy tears, of each p. *. gum p. i. *. saffron p. ii. *. fresh rose leaves, p. iv. *. which are brought to a consistence, either by rain water, or light wine, inclining to rough. And it is not improper to boil pomegranate bark, or melilot, in wines, then to bruise it; or to mix black myrrh with rose leaves; or henbane leaves boiled with the white of an egg; or meal, with acacia juice, or passum, or mulse. And if poppy leaves too be added, they will be somewhat more efficacious. When some one of these is prepared, the eyes ought to be fomented with a penecillum squeezed out of a warm decoction of myrtle or rose leaves in water; after that, the medicine is to be applied. Besides, the skin in the back of the head is to be cut, and a cupping vessel applied to it. If, by these means, the eye is not restored to its place, but continues prominent as before, we may conclude the eye-sight is gone; and that the eye will next grow hard, or be converted into pus. If the suppuration appears in that angle, which is next the temple, an incision must be made in the eye, that vent being given to the matter, the inflammation and pain may cease, and the coats _of the eye_ fall inward, so that the face may be less disfigured afterwards. And then must be used, either the same collyriums with milk, or an egg; or else saffron mixed with the white of an egg. But if it has grown hard, and is mortified, without turning to pus, so much of it must be scooped out, as to prevent a shocking projection; which must be done thus. The external coat must be laid hold of with a hook, and below that the incision made with a knife; then these medicines are to be injected, till the pain be entirely gone. The same medicines are also necessary for an eye, that is first protruded, and afterwards bursts in several places. [Sidenote: _Of carbuncles of the eyes._] It is not uncommon for carbuncles to proceed from an inflammation, sometimes in the eyes themselves, sometimes in their lids; and in the last, they are sometimes in the inside, at other times on the outside. In this case, a clyster must be given; the quantity of food lessened; milk allowed for drink; that the offending acrimony may be sheathed. As to cataplasms and medicines, we must use such as have been proposed against inflammations. And here also the collyrium of Nileus is the best. But if the carbuncle be on the external part of the eye-lid, lintseed boiled in mulse is the most proper for a cataplasm; or if that is not to be had, wheat meal boiled in the same manner.
