In an earlier paper Shaw and myself1 described some pituitary glands from epileptics, our conclusions being that in epileptics the gland was below the average normal weight and that in it were islands of connective tissue, possibly connected with the blood-supply, but apparently not elsewhere described. We gave no description of the bony fossa in which the gland lies, other than to point out that the fossa was often decidedly larger than the contained gland.
Since the publication of our paper, Johnson2 has described changes in the bony structures composing the sella turcica in epileptics, these changes consisting of a roofing of the fossa, contraction of the fossa itself, and a thickening or increased density of the bone bounding the sella. L. Pierce Clark3 has noted this roofing in a few cases, but unaccompanied by corresponding changes in the physical make-up or variations in the type of the epilepsy. On
