    however, ordinary fibrous, bony and fatty tissues are so intimately connected with each other that there would be nothing surpris- ing in all three of these occurring in a tumour (a kind of “ mesoblastic teratoma ”) growing from an aberrant fragment or remnant of embryonic mesoblast,1 and as a matter of fact, whenever true bone or fatty tissue occurs in tumours, the bone or the fat seems to be preceded by, and directly formed from fibrous (or embryonic “fibro-blastic”) tissue, excepting in tumours which contain both bone and cartilage and in which the growth of the former proceeds from the latter. The occurrence of cysts in connection with osteomata of the brain would be intelligible on the “mesoblastic teratoma” theory. The osteomata in various parts of the brain described by A. Bidder,2 W. Ebstein,3 F. Meschede,4 Ranvier,5 Robert Hooper,0 L. Witkowski,7 and Virchow,8 concern us less. In Bidder’s case the tumour was situated in the corpus striatum of a man, aged 59 years. The large osteoma described by Ebstein was found embedded in the left half of the cerebellum of a woman, aged 44 years, and measured 4-5 by 2’9 by 3’2 centimetres. It contained spaces filled with bone-marrow and was separated from the brain-substance by a connective-tissue capsule. In Meschede’s case the patient was an epileptic and imbecile man, aged 30 years, and the osteoma, embedded in the left frontal lobe, was as large as a walnut; ou its upper surface was some gelatinous myxomatous tissue. In Ranvier’s case the bony tumour was embedded in the cerebellum; it was nearly spherical in shape and about two centimetres in diameter. Robert Hooper knew of two cases of apparently true bony tumour of the brain. One 1 See Thomson Walker, loc. cit., and A.
