Results obtained are summarized as follows:
1. Clear hair cuticular scale impressions are easily obtained by microprinting method using lacquer or nail varnish as printing medium,

1) Basic types:
From root to 1 cm, the majority of samples showed type j , Type I appeared mostly between 3 and 4 cm. Type ][ appeared uniformly between 1 and 11 cm, but sparsely compared to other types. Type If appeared uniformly between 1 and 12 cm,
2) Subordinate types:
The subordinate types appeared less frequently than the basic types, Type A, was comparatively numerous between 2 and 3cm. Type B appeared evenly from 1 to 11 cm, except that it reached a special peak at 5 cm, Type C appeared between 1 and 5 cm, but sparsely compared to other types, Type B was sparse until 10cm, but then rose steeply until 15 cm.
