invariably shows that the virile power diminishes in exact proportion
to the extent of duplication. Taylor quotes a description of a
monster, exhibited in London, with two distinct penises, but with only
one distinct testicle on either side. He could exercise the function of
either organ.

Schenck, Schurig, Bartholinus, Loder, and Ollsner report instances of
diphallic terata; the latter case a was in a soldier of Charles VI,
twenty-two years old, who applied to the surgeon for a bubonic
affection, and who declared that he passed urine from the orifice of
the left glans and also said that he was incapable of true coitus.
Valentini mentions an instance in a boy of four, in which the two
penises were superimposed. Bucchettoni speaks of a man with two penises
placed side by side. There was an anonymous case described of a man of
ninety-three with a penis which was for more than half its length
divided into two distinct members, the right being somewhat larger than
the left. From the middle of the penis up to the symphysis only the
lower wall of the urethra was split. Jenisch describes a diphallic
infant, the offspring of a woman of twenty-five who had been married
five years. Her first child was a well-formed female, and the second,
the infant in question, cried much during the night, and several times
vomited dark-green matter. In lieu of one penis there were two,
situated near each other, the right one of natural size and the left
larger, but not furnished with a prepuce. Each penis had its own
urethra, from which dribbled urine and some meconium. There was a
duplication of each scrotum, but only one testicle in each, and several
other minor malformations.

Gore, reported by Velpeau, has seen an infant of eight and one-half
months with two penises and three lower extremities. The penises were 4
cm. apart and the scrotum divided, containing one testicle in each
side. Each penis was provided with a urethra, urine being discharged
from both simultaneously. In a similar case, spoken of by
Geoffroy-Saint-Hilaire, the two organs were also separate, but urine
and semen escaped sometimes from one, sometimes from both.

The most celebrated of all the diphallic terata was Jean Baptista dos
Santos, who when but six months old was spoken of by Acton. His father
and mother were healthy and had two well-formed children. He was easily
born after an uneventful pregnancy. He was good-looking, well
proportioned, and had two distinct
