I use a rectangularly curvedblunt probe which, in order to measure the distance from the ex-ternal orifice of the ear, is marked on the anterior end of every5 mm. The examination is made as follows : the point of the probeis pushed between the polypus and the wall of the meatus, andafter passing round the larger circumference of the growth, it isgradually advanced into the deeper parts. When the instrument,at a depth less than the distance of the external orifice of the earfrom the membrana tympani, comes against an obstacle which pre-vents the circular motion of its point, it may be concluded that theobstacle is caused by the root of the polypus. If, at the examination of an aural polypus, the point of the probe coniesagainst an obstacle at a depth of 16 mm., it is almost certain that the rootof the polypus arises in the external meatus ; while in cases in which the.

By the circularmovements of the probe we sometimes can make out, from the distance of thetwo places at which the point of the probe is impeded in its movement, whatthe width of the root of the polypus is. The greater this distance is, thebroader the root of the polypus. If, on examination, the polypus is verymovable, there is likely to be a narrow and thin pedicle. When it is not somovable, the root of the growth will be broader, and its separation willnaturally be more difficult than that of the thin-pedicled polypus. Excep-tionally a polypus springing from the cavum tympani may be adherent to thewall of the meatus, and may simulate a polypus of the meatus. With larger perfo
