with the right index finger amputated, the left index finger being an ulnar loop, would be searched first in the amputation group for the classification, then reference searches would be conducted in the following groups in the nonamputation files:

S 1 U III S 1 T II S 17 W III
S 1 U IIIS 1 U IIIS 1 U III
S 1 U OII S 1 R III S 17 W MII
S 1 U IIIS 1 U IIIS 1 U III
S 1 A II S 1 R OII S 17 W OII
S 1 U IIIS 1 U IIIS 1 U III

All prints bearing unprinted or badly crippled fingers are filed in the nonamputation files, and reference searches are conducted in the amputation group.

For the purpose of determining if it is feasible to conduct reference searches in all possible classifications, the method of referencing amputations is applied to completely scarred patterns (Chapter titled "[Scarred Patterns—Amputations—Missing at Birth]"). For example, a print bearing the preferred classification:

13 O 17 W OOO 14
L 17 U OOI

with the left middle finger completely scarred, the right middle finger being an ulnar loop with a ridge count of 13, would be searched first in the group for that classification, then reference searches would be conducted in the following groups:

O 17 W OOO O 17 W O 19 W OOO
L 17 U OIIL 17 UrL 17 U OOI
