Abstract
- The article presents information on examining suspects through the method of finger-prints in clay. Where men are and where men have been there occur various traces, or tracks. The traces to be considered here are of a single kind, impressions of the fingers' on things which have been handled or touched. A finger may leave its imprint as a transferred film of natural skin secretions or of some other medium with which the finger has been smeared, and if the digit is pressed into a plastic substance such as clay its impression is then in the form of a mould, shallow or deep in accord with variable conditions of imprinting. At least some of the figures were cast in moulds, and the manufacturing significance of the indent of a thumb or finger is readily apparent. In so casting a small head the most natural procedure would be to use a digit in pressing the soft clay into the mould. In many specimens the finger imprints lack signs of the skin ridges, as if rubbing had effaced them or the clay were not of optimum consistency and texture to register these details.
