VAN DUYSE and MOYART observed, in an infant of 6 weeks, a congenital hard tumor under the inner-upper margin of the left orbit, pushing the eye forward and outward. The tumor presented none of the characteristic symptoms of meningocele, and by its rapid growth threatened the eye. When cut down upon, a tough white cyst-wall was found, which, when divided, collapsed after giving exit to a clear, watery liquid. Internal to this cyst was a much smaller one, from which great quantities of cerebro-spinal fluid were withdrawn by aspiration, showing its connection with the cranial cavity. This case, then, was one of meningo-encephalocele consisting of 2 segments, the outer one cut off, the inner still in connection with the brain. The infant recovered.
