on he is very amiable, but rather grave beyond his years.
He shows great affection for his father, and is as playful and as happy
as the ordinary child. He sleeps soundly, has a good childish appetite,
and appears to be in perfect health. His motions are quick but not
nervous, and are as well coordinated as in a child of ten. In fact, he
impresses one as having the intelligence of a much older child than
three years (now five years), but his height, dentition, and general
appearance indicate the truthfulness of the age assigned. An evidence
of his symmetrical mental development appears in his extreme
inquisitiveness. He wants to understand the meaning of what he is
taught, and some kind of an explanation must be given him for what he
learns. Were his memory alone abnormally great and other faculties
defective, this would hardly be the case; but if so, it cannot at
present be determined.

"His complexion is yellow, with African features, flat nose, thick lips
but not prognathous, superciliary ridges undeveloped, causing the
forehead to protrude a little. His head measures 19 inches in
circumference, on a line with the upper ear-tips, the forehead being
much narrower than the occipitoparietal portion, which is noticeably
very wide. The occiput protrudes backward, causing a forward sweep of
the back of the neck. From the nose-root to the nucha over the head he
measures 13 1/2 inches, and between upper ear-tips across and over the
head 11 inches, which is so close to the eight-and ten-inch standard
that he may be called mesocephalic. The bulging in the vicinity of the
parietal region accords remarkably with speculations upon the location
of the auditory memory in that region, such as those in the American
Naturalist, July, 1888, and the fact that injury of that part of the
brain may cause loss of memory of the meaning of words. It may be that
the premature death of the mother's children has some significance in
connection with Oscar's phenomenal development. There is certainly a
hypernutrition of the parietal brain with atrophy of the optic tract,
both of which conditions could arise from abnormal vascular causes, or
the extra growth of the auditory memory region may have deprived of
nutrition, by pressure, the adjacent optic centers in the occipital
brain. The otherwise normal motion of the eyes indicates the nystagmus
to be functional.

"Sudden exaltation of the memory is often the consequence of grave
brain disease, an
