inches, slightly glazed. This size is convenient, as it allows
all the space necessary for recording the classification of the prints
and general descriptive information concerning the individual. In the
event the new bureau desires to contribute copies of its fingerprints
to the Federal Bureau of Investigation, the latter will, upon request,
gladly furnish fingerprint cards for the purpose together with
envelopes and instructions on how to take fingerprints. It is
suggested that the new bureau design its cards similar to those
furnished by the Federal Bureau of Investigation, as these have been
designed after special study and have been found to be satisfactory
over a long period of time. Figures 409 and 410 show the fingerprint
side and reverse side of the criminal fingerprint card used by the
Federal Bureau of Investigation.

In classifying and comparing fingerprints it is necessary to use a
magnifying or fingerprint glass. Such instruments can be obtained from
various commercial sources. Figure 411 shows the type of magnifying
glass used by the Federal Bureau of Investigation.

The fingerprint cards should be filed according to fingerprint
classification sequence in cabinets, preferably steel. It is further
suggested that the cabinets be three drawers high, with each drawer
divided into three rows for filing. Such cabinets or similar ones can
be obtained from various commercial sources. Figure 412 shows the type
of fingerprint cabinet used in the Federal Bureau of Investigation.

In order to facilitate the location of classification groups, it is
suggested that guide cards be placed in the rows of fingerprint cards
at frequent intervals. These guide cards should be slightly longer
and heavier than the fingerprint cards and should have small tabs on
the top to hold classification identifying symbols. Figure 413 shows
the type of guide card used by the Federal Bureau of Investigation.
