A latent print developed on paper is too fragmentary for conventional minutiae comparison. The examiner instead studies the size, shape, position, and relative arrangement of the sweat pores along individual ridges. This supplementary method of personal identification is known as:
- A Edgeoscopy
- B Ridgeology
- C Poroscopy ✓
- D Palmistry
Correct answer: C. Poroscopy
Explanation
Poroscopy was introduced by Edmond Locard. It uses the morphological characters of sweat pores, which number roughly 400 per square centimetre of ridge surface, as additional points of identity when ridge detail is limited. Edgeoscopy refers to study of the fine contours of ridge edges, described by Chatterjee, and is a distinct technique. Ridgeology is the modern holistic term for ridge-detail evaluation popularised by Ashbaugh, not specifically pore analysis, and palmistry is fortune telling with no forensic basis.
