    it generally appeared to arise from some undue pressure, exercised on the head while passing through the pelvis; and the other, the atrophic condition, seemed to be an original want of nervous energy in the part. Jiingken thinks congenital ptosis is sometimes hereditary. In a case of this description mentioned by Mr. Lawrence, the lids could not be opened on either side by voluntary ef- fort to more than one-third of the usual extent; and when this was accomplished, the upper palpebra was quite smooth, without any fold between it and the eyebrow. The most remarkable case of congenital ptosis is one recorded by Seller, and figured by Von iVmmon, in which the upper hd was so extremely long as to overhang the margin of the lower. EcTROPiuM is a very rare congenital malformation. Two German writers, however, Loschge and Schiitte, have figured cases of the turning out of the tarsal margin, as existing at birth. In appearance, the congenital form of the aflTection presents nearly the same characters as that subsequently acquired by disease in after life. In Loschge's case there likewise existed lagophthalmus, and the palpebral fissure was partially closed, while in a case submitted by Von Ammon the contrary appearance was presented, for there was imperfect development of the globe or microphthalmus, and strong di- varication of the lids, together with great aversion, as shewn m the preceding wood cut.* ungslXTT ^^^ und Rosenmuller's Bcitrage, z.
