Structure of the hair
---------------------
The microscopic structure of the skin
surface is furrowed; the hair follicles are
narrow with straight edges. The average
follicle contains three or four hair shafts.
The fine fur fibres are elliptical in
cross-sectional outline and they are from The cuticular structure
18 µm thick. The cuticular scales are of the fine fibres, 2000x
cornet-like in the bottom part and of the
raised petal-like type in the middle and upper parts. The scales have the
irregularly grooved surface and straight margins. The medullary column is
usually wide, unbroken and central symmetrical shaped. The overall shaped of
the medulla is the sponge-cortex-like type with a foam-like structure to the
infilling substance.

The guard hairs are elliptical in cross-section and covered by even,
tile-like scales, with a smooth surface and straight scale margins. The
medulla is wide, unbroken and central-symmetrical in cross-section. The
overall medullary structure is of the cortex-foam-like type with a foam-like
