Beneath the posterior rounded border of the corpus callosum is thetransverse fissure of the cerebrum, which extends between the hemi-spheres and crura cerebri from very near the fissure of Sylvius onone side, to the same point on the opposite side of the brain. It isthrough this fissure that the pia mater communicates with the velum * James Dubois, a celebrated professor of anatomy in Paris, where he succeededVidius in 1550, although known much earlier by his works and discoveries, but particu-larly by his violence in the defence of Galen. His name was Latinized to JacobusSylvius. 34 398 CEREBRUM—LATERAL VENTRICLES, Fig. 165.*. interpositum. And it was here that Bichat conceived the arachnoidto enter the ventricles; hence it is also named the fissure of the middle line of the corpus callosum is the raphe, a lineardepression between two slightly elevated longitudinal bands (chordaelongitudinales Lancisii); and on either side of the raphe may be seen the LinecB transversa?, which markthe direction of the fibres of whichthe corpus callosum is fibres may be traced into thehemispheres on either side, and theywill be seen to be crossed at aboutan inch from the raphe by the longi-tudinal fibres of the covered band ofReil. Anteriorly and posteriorly,the fibres of the corpus callosumcurve into their corresponding , now, a superficial incision bemade through the corpus callosumon either side of the raphe, twoirregular cavities will be opened,which extend from one extremityof the hemispheres to the other:these are the lateral ventricles
