    an inch in length ; they were set as closely to- gether as the hairs of a brush, and extended in an undulating line over a space of about two square inches in extent.* The tables of the skull were slightly separated from each other in the part corresponding to the exostosis, and the diploe seemed to contain some of the same brain- like matter which formed the bulk of the tumour. It is of course impossible to decide whether in this case the disease commenced in the soft parts, or in the bone *, but it seems probable that it commenced in the bone, because the spiculee were furnished by the bone itself, and not by the periosteum or dura mater, which were separated by the tumour to the distance of nearly an inch from the outer and' inner tables of the skull respectively. In malig- nant osteosarcoma^ however, it is more usual to find a deficiency than an excess of bony matter, for although spiculse of bone are inter- spersed through the brain-like matter which - forms the bulk of the tumour, the bone itself is usually divested of its earthy basis, and is con- verted into a steatomatous or cartilaginous sub- stance. Sometimes, however, the tendency to secrete phosphat of lime is surprizingly encreased, and then large and singularly shaped masses of bony matter are thrown out from the surface of the diseased bone.t * See Preparation, B. 26, Museum of the College of Sur- geons, and Plate. t See Preparation No. 9 and 10 in the Museum of the Royal College of Surgeons, in which the earthy deposition from the head of the tibia weighed several pounds.
