CHAP. VIII. Of the Hydatis or Fatnesse of the Eye-lids.
THe Hydatis is a certaine fatty substance like a peece of fat seated and ly∣ing * 1.1 under the skinne of the upper eye-lid. It is a disease incident to chil∣dren, who are of a more humid nature: wherefore it is a soft and loose tumour making the whole eye-lid, which it possesseth, oedematous; so that, as if depressed with a weight, it cannot be lifted up. It hath its name, for that it hath as it were a bladder distended with a whayish humour, which kinde of fault is observed by Galen in the liver. Those, who are thus affected, have their eyes looke * 1.2 red, and flow with teares, neither can they behold the sun, or endure the light. The cure is performed by cutting off the superfluous substance, not hurting the neigh∣bouring * 1.3 parts; and then presently put some salt into the place whence it was taken out (unless the vehemency of paine hinder) that so the place may bee dryed and strengthened, and the rest of the matter (if any such be) may be consumed, and hin∣dred from growing againe. Lastly, you shall cover the whole eye with the white of an Egge dissolved in rose-water, or some other repercussive.
