such instances, and modern illustrations are constantly reported.

Menstruation in Man.--Periodic discharges of blood in man,
constituting what is called "male menstruation," have been
frequently noticed and are particularly interesting when the
discharge is from the penis or urethra, furnishing a striking
analogy to the female function of menstruation. The older authors
quoted several such instances, and Mehliss says that in the
ancient days certain writers remarked that catamenial lustration
from the penis was inflicted on the Jews as a divine punishment.
Bartholinus mentions a case in a youth; the Ephemerides several
instances; Zacutus Lusitanus, Salmuth, Hngedorn, Fabricius
Hildanus, Vesalius, Mead, and Acta Eruditorum all mention
instances. Forel saw menstruation in a man. Gloninger tells of a
man of thirty-six, who, since the age of seventeen years and five
months, had had lunar manifestations of menstruation. Each attack
was accompanied by pains in the back and hypogastric region,
febrile disturbance, and a sanguineous discharge from the
urethra, which resembled in color, consistency, etc., the
menstrual flux. King relates that while attending a course of
medical lectures at the University of Louisiana he formed the
acquaintance of a young student who possessed the normal male
generative organs, but in whom the simulated function of
menstruation was periodically performed. The cause was
inexplicable, and the unfortunate victim was the subject of deep
chagrin, and was afflicted with melancholia. He had menstruated
for three years in this manner: a fluid exuded from the sebaceous
glands of the deep fossa behind the corona glandis; this fluid
was of the same appearance as the menstrual flux. The quantity
