Structure of the hair
---------------------
The microscopic appearance of the skin
surface is regularly grooved and the upper
part of the follicles is narrow with
straight edges. The average follicle
contains only one hair.
The fine fur fibres are of circular The cuticular structure
cross-section and the cuticular scales are of a guard hair, 400x
of the cornet-like type. The surface of the
scale is smooth and the scale margins are straight. The diameter of these
fibres is in the range of 8 to 15 µm. The fine fur fibres are non-medullated.

The intermediate fibres are elliptical
in cross-sectional outline, with a diameter
of 50 to 70 µm. The cuticular scales are of
the flat even, tile-like type with
non-regular grooved surface and straight
scale margins. The medulla is narrow,
unbroken longitudinally and central
symmetrical-shaped. The overall medullary
structure is of the spongelike type and the The cuticular structure
medullar infilling substance is of a foam of a guard hair, 2000x
-like structure.
The guard hairs are elliptical and are 70 to 110 µm in diameter. The
cuticle is composed of even, tile-like scales with a regularly grooved
surface and straight scale margins. The medulla is narrow, unbroken and
central symmetrical-shaped. The overall medullary structure is of the
spongelike type and infilling substance is foam-like.
