Palpebræ

On reaching the internal angle of the palpebræ, the tears accumulate in the lacus lachrymalis, a small space formed between the edges of the palpebræ kept separated from each other by the caruncula lachrymalis.

Inflammation of the eye-lids is very commonly observed to attend some of the more violent forms of ophthalmia, and more particularly the purulent variety; but the disease of which we are now to treat is an idiopathic affection, and confined, or nearly so, to the palpebræ. / Symptoms.—It is most frequently witnessed in children, commonly attacking the palpebræ of only one eye, and the upper eye-lid is more considerably affected than the lower one.

The snake-like forms of the families of the Lacertilia Leptoglossa greatly predominate in the Southern Hemisphere; also those with undeveloped palpebræ.
