The cuneiform bone is not perforated like a sponge

For it is by no means perforated by little holes of that sort, but appears continuous and solid throughout its surface; and if it ever lacks closed cavities, it is not at all different from the makeup and configuration of the talus, the calcaneus, or other such bone that is wrapped and covered on the outside by a continuous scale and is filled only on the inside with small cavities, as in the finest pumice. Where the cuneiform bone is so thick and faces the inside of the skull, it has a certain cavity [sella turcica, fossa hypophysialis] (M in figure 6) in which Nature has placed a small gland [hypophysis (glandula pituitaria)] (A in Book 7, figure 16) that receives the runoff of phlegm. 113 From this cavity, smooth passages then run on each side that carry off the phlegm. For it would be impossible, even if we should grant that this bone is perforated like a sponge on its surface, that phlegm would be carried by such foramina. But it will be more suitable to explain the passages or cavities hollowed out for the phlegm together with our presentation of the foramina of the head bones in the twelfth chapter, and to postpone the drainage of phlegm until the seventh Book, which will be dedicated to the brain. Here, our concern is with basic knowledge of the bones. The processes of the cuneiform bone which it shows inside the skull at the sides of the cavity mentioned will in the end be better understood when we have explained that cavity and the foramina of the bone.
