THE KEY: The key is obtained by counting the ridges of the first loop
appearing on the fingerprint card (beginning with the right thumb),
exclusive of the little fingers which are never considered for the key
as they are reserved for the final. The key, no matter where found, is
always placed to the extreme left of the numerator of the
classification formula (fig. 353).

_Extensions_

THE SECOND SUBSECONDARY CLASSIFICATION: When a group of fingerprints
becomes so large that it is cumbersome and unwieldy, even though fully
extended, it can be subdivided further by using a second subsecondary
division, which is brought up into the classification formula
directly above the subsecondary, and for which the symbols S, M and L
are used. The following table is used:

_Index_ _Middle_ _Ring_

1 to 5, inclusive, S. 1 to 8, inclusive, S. 1 to 10, inclusive, S.
6 to 12, inclusive, M. 9 to 14, inclusive, M. 11 to 18, inclusive, M.
13 or more, L. 15 or more, L. 19 or more, L.

If this table is referred to, a study of figure 352 will demonstrate
the use of the second subsecondary.
