tained for deceased persons, for
possible future reference.

A separate file should be maintained for all prints bearing
amputations and which have an unequivocal statement or marking from
the contributor to that effect.

Permanent scars also may be utilized for this purpose, giving three
more groupings: those prints having permanent scars in the right hand,
those having a scar in the left, and those in which scars appear in
both hands. A separate file may be maintained for mutilated prints
whether or not the permanent-scar division is used. This is usually
composed of prints so badly mutilated, or so mutilated about the cores
and deltas, that intentional mutilation is suspected.

_Classification of Scarred Patterns--Amputations--Missing at Birth_

_Classification of scarred patterns_

Emphasis should be placed upon the necessity for fully referencing all
scarred patterns. In connection with their proper classification, the
following rules should be observed:

- When an impression is so scarred that neither the general
type of pattern nor the ridge tracing or count can be
determined with reasonable accuracy, the impression should
be given both the general type value and the
subclassification value of the corresponding finger of the
other hand.

- When an impression is partially scarred, i.e., large scars
about the core so that the _general type_
