Abstract: A technique for making a permanent imprint of trichoglyphs (cowlicks). A liquid solvent is applied to the surface of the trichoglyph. A flexible sheet of solvent-soluble material is pressed over the wetted trichoglyph area. The sheet is marked and indexed with respect to externally recognizable anatomical features of the animal adjacent to the trichoglyph area. This results in the impression of the trichoglyph configuration in geometric relation to indexed markings on the sheet indicative of the position of the trichoglyph on the body of the animal. The sheet is subsequently removed and dried. The resulting impression can be used to produce prints for later comparison purposes and for recording of the trichoglyph features.
