once suspected the causes of his symptoms.

Wrench mentions a case illustrative of the extent to which imagination
may produce symptoms simulating those ordinarily caused by the
swallowing of false teeth. This man awoke one morning with his nose and
throat full of blood, and noticed that his false teeth, which he seldom
removed at night, were missing. He rapidly developed great pain and
tumor in the larynx, together with difficulty in deglutition and
speech. After a fruitless search, with instrumental and laryngoscopic
aid, the missing teeth were found--in a chest of drawers; the symptoms
immediately subsided when the mental illusion was relieved.

There is a curious case of a man drowned near Portsmouth. After the
recovery of his body it was seen that his false teeth were impacted at
the anterior opening of the glottis, and it was presumed that the shock
caused by the plunge into the cold water had induced a violent and deep
inspiration which carried the teeth to the place of impaction.

Perrin reports a case of an old man of eighty-two who lost his life
from the impaction of a small piece of meat in the trachea and glottis.
In the Musee Valde-Grace is a prepared specimen of this case showing
the foreign body in situ. In the same museum Perrin has also deposited
a preparation from the body of a man of sixty-two, who died from the
entrance of a morsel of beef into the respiratory passages. At the
postmortem a mobile mass of food about the size of a hazel-nut was
found at the base of the larynx at the glossoepiglottic fossa. About
the 5th ring of the trachea the caliber of this organ was obstructed by
a cylindric alimentary bolus about six inches long, extending almost to
the bronchial division. Ashhurst shows a fibrinous cast, similar to
that found in croup, caused by a foreign body removed by Wharton,
together with a shawl-pin, from a patient at the Children's Hospital
seven hours after the performance of tracheotomy. Search for the
foreign body at the time of the operation was prevented by profuse
hemorrhage.

The ordinary instances of foreign bodies in the larynx and trachea are
so common that they will not be mentioned here. Their variety is
innumerable and it is quite possible for more than two to be in the
same location simultaneously. In his treatise on this subject Gross
says that he has seen two, three, and even four substances
simultaneously or successively penetrate the same location. Berard
