 lateral sinus. Occipiia'lis, opens into occipital vein or sinus. 



Cerebralea I noted for their thin coats, muscular tissue and 

 absence of valves. Superidrcs, (j or 8 on each side) for- and 

 inwards to superior longitudinal sinus, there receivinginterior 

 cerebral which drain the same hemisphere. Inferio'res antcri-
