CHAP. XXXIII. Of Liquid medicines for the eyes.

COllytion, and Collurion, as much as to say Collurion, * 1.1 that is Colobon ten Ouran, or Colobee Oara, it is so called because it is like mutisarae caudae, in which forme although various medicines appointed for various uses, were hereto∣fore prepared: yet at this day by the name Collyries, are understood only externall medicines proper for the Eyes.

But medicines which are exhibited to the Eyes, and in generall have borrowed their name from those dry ones, * 1.2 are named Collyries, and are commonly divided into dry and moist, dry ones are made when medicines pounded very small, are made fine in a Morter, and with a sufficient quantity of Whites of Eggs, or of some Muscellage, are made into the forme of a Py∣ramid, or Trochees, and are dryed in the shade

when there is need of them, they are beaten againe, in a marble, or Stone Morter, some convenient Liquor being powred in, and the Liquor, afterwards, which is then pre∣pared, is dropt into the eyes.

2. Moist Collyries are twofold, for either they are dropt into the Eyes, in the forme of a Liquor, which is made of juices, distilled waters, Decoctions, or many of these mixt, powders being added, and espcially of those medicines which will dissolve in a moist body.

3. Or they are made in the forme of an unguent.

4. Lastly, convenient medicines also, are boyled in water, and the warme Vapour exhaling out of the pot, which is covered with a linnen cloath, is received into the eyes.
