ut straight horizontally high
upon the forehead, which thus showed a considerable slant backward from
the brow to the base of the hair. A small pigtail hung behind the head.
The hair at the sides was left to grow down so as fully to cover the
lobes of the ears, where again it was cut horizontally at the sides and
back of the head. The top of the head was of great height, quite unlike a
Mongolian cranium.

The eyes--close to the nose, and of a shiny dark brown--had their long
axis nearly in one horizontal plane. They were set rather far back, were
well cut, with thick upper eyelids, and placed somewhat high up against
the brow ridges so as to leave little room for exposure of the upper lid
when open.

None of the other Indians, who had gradually assembled, wore a particle
of clothing, barring a tight conical collar of orange-coloured fibre
encircling their genital organs--so tight that it almost cut into the
skin. Without this solitary article of clothing no Indian man will allow
himself to be seen by another, less still by a stranger. But with so
modest an attire he feels as well-dressed as anybody. I think that this
elegant article of fashion must have originated as a sanitary precaution,
in order to prevent insects of all kinds, and particularly _carrapatos_,
penetrating within--or else I was really at a loss to understand of what
other use it could be. They themselves would not say, and only replied
that all Bororo Indian men wore it. The Indians who had assembled all
belonged to the Bororo tribe.

On that, as well as on later occasions, I noticed two distinct types
among the Bororos: one purely Papuan or Polynesian; the other strongly
Malay. The characteristics of those two different types showed themselves
markedly in every instance. The majority were perhaps of the Malay type.
I was intensely interested at the astounding resemblance of these people
to the piratical tribes of the Sulu Archipelago in the Celebes Sea,
where, too, one met a considerable amount of mixture of those two types
as well as specimens of pure types of the two races.

Among the Bororos many were the individuals--of the Malay type--who had
the typical Malay eye _a fleur de tete_, prominent, almond-shaped, and
slightly slanting at the outer angle. The nose--unlike that of Papuan
types--was flattened in its upper region between the eyes, and somewhat
button-like and turned up at the lower part--just the reverse of the
Papuan types, who had pr
