Serous Cysts of the Orbit.  —At the meeting of the Académie de Médecine on December 14, M. Panas read a communication on "The Pathogenesis of so-called Serous Cysts of the Orbit." The greatest obscurity has hitherto attached to the nature and pathological signification of these cysts. After a careful consideration of the subject M. Panas draws the following conclusions:

  1. These cysts, without exception, are of congenital origin, even when their presence is not manifested until an advanced age.

  2. They present seats of election, corresponding with the bronchial clefts of the embryo.

  3. Their contents (epithelium, hairs, teeth, solid or liquid fat) may vary without the dermoid origin being doubtful, and this is due to the histological constitution of their walls.

M. Panas gives the record of an interesting case, with a full histological account of the cyst.—Bulletin de l'Académie de Médecine, No. 50, 1886.
