    11. Anomalies of Hearing of Extra-Labyrinthine Origin. Subjective noises which can also be distinguished by the physician upon the application of a suitable auscultation tube to the affected ear, are phenomena of very rare occur- rence. For their production it is only necessary that a band of cicatricial tissue should press sufficiently upon some arteriole in the vicinity of one of the ossicles (e.y., the stapes). As to the origin of those noises which offer a dis- tinctively musical character—both to the patient and to the examining physician—it is probable that some other ex- planation than that which has just been given will be re- quired. It is conceivable that a slender band of connective tissue, free at all points except at the opposite ends, may be set in musical vibration by an arteriole which passes in close proximity to one of its points of attachment. 12. Cerebral Embolism Simulating Labyrinthine Disease. The existence of cardiac disease, at the aortic valves— in one of my patients who was suddenly seized with a severe pain in the head, vertigo, nausea, and loud noises in both ears, and who at the same time saw all objects doubled, and lost completely the power of hearing what was said to him —warranted the suspicion that an embolism had taken place in or near the medulla oblongata. The return of a con- siderable fraction of the hearing at the end of six days, and the entire disappearance of double vision after the lapse of a few weeks, gave still further strength to this hypothesis. This patient came under my observation nearly thirty years ago, and since then, so far as I can remember, no similar case has presented itself.
