These aneurysms are prone to rupture into the brain substance and cause intracranial pressure, and at times motor weakness. Figs. 18 and 19 (Cases III and XVIII) are examples. Literature on Aneurysms of the Anterior Cerebral and Anterior Communicating A rtcries Reports of pathological cerebral and communicating1 O specimens of aneurysms of the anterior arteries are quite numerous. These aneu- I *g. 18. Case 14, Table C. Aneurysm of the anterior cerebral and anterior com¬ municating arteries. The mass had produced a filling defect in the anterior part of the third ventricle and was demonstrated by ventriculography. rysms are more various in character than those of the other cerebral vessels, and more of this type have been found at necropsy. Weir Mitchell (1889) reported a rare specimen of a midline aneurysm into which both carotid arteries entered with a connecting branch between. From his diagnosis one should wonder whether this repre¬ sented the anterior cerebral and anterior communicating arteries. The patient had bitemporal hemianopsia, and from the necropsy specimen obtained elsewhere he asserted that there was no optic chiasm. Ebstein (1874) reported a long, diffuse aneurysm of an im-
