Note 122 — Chapter XIII · OF SICKNESSES OF HOUNDS AND OF THEIR CORRUPTIONS

Pterygium, name for the "sickness" in the eyes of hounds which our MS. describes as a "web coming upon them." It is called pterygium from its resemblance to an insect's wing; is an hypertrophy of the conjunctiva or lining membrane of the eye, due to irritation; it extends from the inner angle to the cornea, which it may cover: the treatment is excision. The cure for "the nail" mentioned in our MS. of hanging a collar of elm leaves round the dog is taken by G. de F. (p. 92) from Roy Modus xliv., where it is given without the saving clause "Mès cela est bien petit remède."
