    degree, have been figured by continental authors since then. It has only been observed in one eye at a time, and is fre- quently to be found in connexion with hare-lip, and simi- lar vices of conformation of a light character. As in hare-lip, so in cleft eyelid, it is chiefly and gene- rally confined to the upper. Heyfelder found it in conjunc- tion with hare-hp and coloboma iridis. St. Yves and Beer have noticed instances of cleft eye-lid, and the sketch be- neath is copied from Von Ammon's great work, who, how- ever, asserts that coloboma palpe- brae occurs as well in the upper as in the lower lid, and states this remarkable similarity to hare- lip, that as in it the mucous mem- brane turns outward along its margin, in the same manner that it does in the red border of the normal lip, so the ciHae, and other peculiarities of the tarsal margin, dip into and border the un- natural cleft, as well as the rest of the natural tarsus. Blasius of Halle, has described a malformation under the name of ectopia tarsi, consisting of a fold or reduplication of the conjunctiva of the upper lid, which, extending from can- thus to canthus, and faUing like a curtain over the front of the globe below the margin of the upper lid, obscured the greater portion of the cornea. As the learned Professor had never seen the person (a woman, aged 37), during life, it is very doubtful whether it ought to be recorded as a congeni- tal deformity or not. From his own description it appeared to me not unlike an old ptyregium crassum. No account could be obtained from the friends of the person who was the subject of this disease.* Alterations in the colour of the eyelids, styled blepha- ROBYSCHOREA, are not uncommon affections : they are gene- rally the result of n^evi, the well-known disease of the cutis. * Von Ammon—Zeitschriff fur Ophthalmologic,—Bd. 4, 1634, p. 160.
