III. A very dense tumor, of a uniform whitish or ash colour, and exhibiting the appearance and the pro- perties of coagulated albumen. This substance is found in distinct rounded tumors of various sizes, which are generally attached to the dura mater, and do not ap- pear to he covered by any cyst. I have described one which grew on the falx in Case LXXXVII., nearly five inches in circumference, and uniformly white and firm in its consistence ; it did not appear to be organized, and when analyzed exhibited the properties of coagu- lated albumen. The remaikable circumstance in this case Mas, that no urgent symptoms arose from the presence of this mass until a few weeks before death. Tumors of this kind sometimes arise from the external surface of the dura mater ; in this case they have been frequently known to produce absorption of the bone, and to rise externally under the integuments of the head, so as to be mistaken for wens. Many cases of this kind are mentioned by the French ivriters. In some of them, the disease seems to have been originally, excited by injuries ; and in others, an injury appears to have accelerated the process by which the tumor was making its ivay through the bone. When these tumors have been rashly meddled ivith by incision, death has generally been the consequence, ymall tumors which resemble those of this class, are sometimes met with attached to the choroid plexus. I have seen one in each lateral ventricle, the size of small hazel nuts, in a nian ivho died suddenly after having had repeated epi- leptic attacks at long intervals, and having been for some time affected with symptoms threatening apo- plexy. IV. Tumors externally resembling those of the former class, but internally ])resenting an organized appearance, and a reddish or flesh-colour, resembling the substance of the kidney. Ihese are met ivith in various situations ; one will be described, the size of an egg, which greiv from the tentorium.
