We can deter mine its existence when it occurs in the lung, kidney, or liver, by finding some of the hydatids in the expect oration, urine, or l'acees; or if there is an opening in the wall of the abdomen, for instance, attended 'with dis charge. In regard to the polypoid tumor, that occurs always in the outlets of the body, the nose, or. Ear, or throat, or maxillary sinus, or in the rectum, the vagina, or the uterus. Usually one can readily determine the nature of the case by inspection, and by means of the touch. The myeloid tumor I believe to be nothing but a variety of encephaloid, and its characteristics distinguish it. If you can remember these facts brought prominently before you, you will have little difficulty in arriving at a correct diagnosis.
