✦ Synopsis

Textbooks in anatomy describe the cranial venous sinuses as endothelium-lined blood spaces between the outer and the inner layers of the cranial dura mater.

Chauveau and Arloing ( ) studied the meninges of domestic animals including the cow, and described the cranial dura mater as a single white fibrous membrane with an external face i n contact with the walls of the cranium, and an internal face which adheres to the arachnoid. They describe the sinuses of the dura mater as vascular spaces in the texture of the dura.

Sisson and Grossman ('47) give a n account of the cerebral dura mater and the cavernous sinuses i n the horse, the pig, the dog, the sheep, and the cow. They state that the cranial dura mater consists of two layers which are intimately adherent to each other i n the adult, and that the venous sinuses are channels between the two layers of the dura lined by endothelium.

However, in connection with a study of the bovine hypophysis, I find that the cavernous sinuses lie entirely within the outer layer of dura. This finding led to the present investigation.
