ompartments by two raphes, and each compartment contained a
testicle. The anus at birth was imperforate, but the child was
successfully operated on, and at its sixtieth day weighed 17 pounds.

Lange says that an infant was brought to Karg for relief of anal
atresia when fourteen days old. It was found to possess duplicate
penises, which communicated each to its distinct half of the bladder as
defined by a median fold. The scrotum was divided into three portions
by two raphes, and each lateral compartment contained a fully formed
testicle. This child died because of its anal malformation, which we
notice is a frequent associate of malformations or duplicity of the
penis. There is an example in an infant described in which there were
two penises, each about 1/2 inch long, and a divided scrotal sac 21
inches long. Englisch speaks of a German of forty who possessed a
double penis of the bifid type.

Ballantyne and his associates define diphallic terata as individuals
provided with two more or less well-formed and more or less separate
penises, who may show also other malformations of the adjoining parts
and organs (e.g., septate bladder), but who are not possessed of more
than two lower limbs. This definition excludes, therefore, the cases in
which in addition to a double penis there is a supernumerary lower
extremity--such a case, for example, as that of Jean Baptista dos
Santos, so frequently described by teratologists. It also excludes the
more evident double terata, and, of course, the cases of duplication of
the female genital organs (double clitoris, vulva, vagina, and uterus).
Although Schurig, Meckel, Himly, Taruffi, and others give bibliographic
lists of diphallic terata, even in them erroneous references are
common, and there is evidence to show that many cases have been
duplicated under different names. Ballantyne and Skirving have
consulted all the older original references available and eliminated
duplications of reports and, adhering to their original definition,
have collected and described individually 20 cases; they offer the
following conclusions:--

1. Diphallus, or duplication of the penis in an otherwise apparently
single individual, is a very rare anomaly, records of only 20 cases
having been found in a fairly exhaustive search through teratologic
literature. As a distinct and well-authenticated type it has only quite
recently been recognized by teratologists.

2. It does not of itself interfere w
