menstruation lasting through a long
sleep. Instances of black menstruation are to be found, described in
full, in the Ephemerides, by Paullini and by Schurig, and in some of
the later works; it is possible that an excess of iron, administered
for some menstrual disorder, may cause such an alteration in the color
of the menstrual fluid.

Suppression of menstruation is brought about in many peculiar ways, and
sometimes by the slightest of causes, some authentic instances being so
strange as to seem mythical. Through the Ephemerides we constantly read
of such causes as contact with a corpse, the sight of a serpent or
mouse, the sight of monsters, etc. Lightning stroke and curious
neuroses have been reported as causes. Many of the older books on
obstetric subjects are full of 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 w
