The walls ofthe cyst usually contain calcific or osseous matter; the amountvaries considerably. Some observers have noted the presenceof an epithelial lining to the inner walls of follicular odon-tomas : it is a point which requires further elucidation. Intwo recent specimens I failed to find an epithelial lining. These tumours are not unknown in other mammals; Ihave seen them in sheep, pigs, and porcupines. In

Intwo recent specimens I failed to find an epithelial lining. These tumours are not unknown in other mammals; Ihave seen them in sheep, pigs, and porcupines. In sheep theyare common, and generally affect the incisors, and are thuslimited to the mandible: as a rule they are bilateral. The amount of fluid in a follicular odontoma varies, andthe size of the tumour depends in the main upon this. Occa-sionally the fluid may measure as much as two ounces, and 214 ODONTOMAS this may lead to the wide separation of the inner and outerplates of the body of the mandible, and the odontoma mayoccupy the whole length of the bone.
