Surgical anatomy : a treatise on human anatomy in its application to the practice of medicine and surgery . nicates with the third ventricle hj way of theaqueduct of Sylvius, and with the central canal of the spinal cord through anopening in the inferior angle which is dilated and is called the ventricle ofArantius. The floor of the fourth ventricle is its most important part, for the reason thatthe nuclei of most of the cranial nerves are situated there. It is composed chieflyof gray matter continuous with the gray matter of the spinal cord. Occujiyingthe middle line of the floor of the fourth ventricle is the median longitudinalfissure. It extends from the posterior oriflce of the acjueduct of Sylvius to the pos-terior or inferior angle of the ventricle, which is at the point of divergence of the PLATE GCLXXXVI.

This fissure is continuous below with the centralcanal of the spinal cord. This portion of the fourth ventricle has received thename of calamus scriptorius because of the resemblance of the longitudinal fis-sure and the diverging posterior pyramids and restiform bodies to the point of apen. Immediately to each side of the median furrow is a longitudinal ridge,the eminentia teres. Crossing this eminence in the lower half of the ventricle arebands of white matter, the auditory stride or striae acusticee. To the outer side ofthe eminentia teres and anterior to the auditor
