The necropsy was performed byDr. Karsner. A very similar tumor of tlie brain has l)een describedrecentl) by Kolpiii.^- It was papillomatous and was re-garded as an adenocarcinoma. It resembled glandulartissue where the tumor processes were cut was sharply defined from the surrounding nervoustissue, but caused no distortion of the tissue about it,so that the growth of the tumor was proportional to the.

Masses of detrituswere found in the center of the tumor, whereas the cen-ter of the tumor in my case had become cystic and thetumor had caused enlargement of the hemisphere. Primary epithelial growths of the brain, Kolpinstates, are rare findings. They arise in the ependymaof the ventricles or the lining of the chorioid plexus andhave a papillomatous formation. Kolpin refers to anumber of reported cases. He believed that the largestof his tumors was the primary growth and that it orig- 12. Kiilpin : Arch. f.
