s esophagus, and allowing water to trickle into
this tube from the spout of an oil-can. The phenomena exhibited by the
rooster were quite interesting. It made all the motions of pecking,
strutted about, flapped its wings, attempted to crow, but, of course,
without making any sound. It exhibited no signs of incoordination, but
did not seem to hear. A ludicrous exhibition was the absurd, sidelong
pas seul made toward the hens.

Ward mentions an instance of congenital absence of the corpora
callosum. Paget and Henry mention cases in which the corpora callosum,
the fornix, and septum lucidum were imperfectly formed. Maunoir
reports congenital malformation of the brain, consisting of almost
complete absence of the occipital lobe. The patient died at the
twenty-eighth month. Combettes reports the case of a girl who died at
the age of eleven who had complete absence of the cerebellum in
addition to other minor structural defects; this was probably the case
mentioned by Cruveilhier.

Diminution in volume of the head is called microcephaly. Probably the
most remarkable case on record is that mentioned by Lombroso. The
individual was called "l'homme-oiseau," or the human bird, and his
cranial capacity was only 390 c.c. Lombroso speaks of another
individual called "l'homme-lapin," or man-rabbit, whose cranium was
only slightly larger than that of the other, measuring 490 mm. in
circumference. Castelli alludes to endemic microcephaly among some of
the peoples of Asia. We also find it in the Caribbean Islands, and from
the skulls and portraits of the ancient Aztecs we are led to believe
that they were also microcephalic.

Two creatures of celebrity were Maximo and Bartola, who for twenty-five
years have been shown in America and in Europe under the name of the
"Aztecs" or the "Aztec children". They were male and female and very
short, with heads resembling closely the bas-reliefs on the ancient
Aztec temples of Mexico. Their facial angle was about 45 degrees, and
they had jutting lips and little or no chin. They wore their hair in an
enormous bunch to magnify the deformity. These curiosities were born in
Central America and were possibly half Indian and Negro. They were
little better than idiots in point of intelligence.

Figure 92 represents a microcephalic youth known as the "Mexican wild
boy," who was shown with the Wallace circus.

Virchow exhibited a girl of fourteen whose face was no larger than that
of a new-born ch
