skin was found to be due to the existence of pigment
similar to that found in the black race. The husband of the woman had a
light brown skin, like an ordinary Fellah man, and it was ascertained
that there were some negro laborers in port during the woman's
pregnancy; but no definite information as to her relations with them
could be established, and whether this was a case of maternal
impression or superfetation can only be a matter of conjecture.

Fantastic monsters, such as acephalon, paracephalon, cyclops,
pseudencephalon, and the janiceps, prosopthoracopagus, disprosopus,
etc., although full of interest, will not be discussed here, as none
are ever viable for any length of time, and the declared intention of
this chapter is to include only those beings who have lived.

CLASS VIII.--The next class includes the parasitic terata, monsters
that consist of one perfect body, complete in every respect, but from
the neighborhood of whose umbilicus depends some important portion of a
second body. Pare, Benivenius, and Columbus describe adults with
acephalous monsters attached to them. Schenck mentions 13 cases, 3 of
which were observed by him. Aldrovandus shows 3 illustrations under
the name of "monstrum bicorpum monocephalon." Bustorf speaks of a case
in which the nates and lower extremities of one body proceeded out of
the abdomen of the other, which was otherwise perfect. Reichel and
Anderson mention a living parasitic monster, the inferior trunk of one
body proceeding from the pectoral region of the other.

Pare says that there was a man in Paris in 1530, quite forty years of
age, who carried about a parasite without a head, which hung pendant
from his belly. This individual was exhibited and drew great crowds.
Pare appends an illustration, which is, perhaps, one of the most
familiar in all teratology. He also gives a portrait of a man who had a
parasitic head proceeding from his epigastrium, and who was born in
Germany the same year that peace was made with the Swiss by King
Francis. This creature lived to manhood and both heads were utilized in
alimentation. Bartholinus details a history of an individual named
Lazarus-Joannes Baptista Colloredo, born in Genoa in 1617, who
exhibited himself all over Europe. From his epigastrium hung an
imperfectly developed twin that had one thigh, hands, body, arms, and a
well-formed head covered with hair, which in the normal position hung
lowest. There were signs of independent
