    it does notjgross the.middle line of the face. Arsenic and quinine may be given internally, and cocaine drops locally to allay the pain. If ulceration of the cornea occurs, it must be treated as such—vide infra. Lupus, Chancres, Epithelioma, and Sarcoma are some- times found on the lids, but do not present any peculiar characters in that situation. Ptosis—drooping of the upper lid—may be congenital or acquired, and complete or partial, and may affect one or both eyes. Causes—Congenital ptosis is bilateral, and is due to \yeakness or absence of the levator palpebrae superioris • acquired ptosis, which generally affects one eye only, to 3 paralysis of that muscle. The latter is therefore often only one symptom in a group, as in Ophthalmoplegia Externa, where all the external muscles of the eye are paralysed. Treatment—In recent cases the usual constitutional treatment may be tried, and failing this, an operation to shorten the lid may be of benefit. The treatment of the congenital form is highly unsatisfactory. Distichiasis and Trichiasis—When the cilia are arranged in a double row, it is called distichiasis ; when irregularly, trichiasis. Either condition may be congenital or the result of diseases of the lid. The misplaced cilia, if they rub against the cornea, soon cause irritation and inflam- mation. Temporary relief may be obtained by plucking them out with forceps (epilation), while a radical cure is eff'ected by destroying the roots of the cilia by electrolysis, or by a plastic operation on the lid altering the direction of its margin. Entropion—A turning in of the margin of the lid, by which the cilia are brought into contact with the cornea. Entropion vtv^y.^jmiscuJ^r_ox organic; the former
