W xX3x.

- to ---- W xX3x

The sequence is as follows: Prints with _c_, _d_, or _x_ in any finger other than the index fingers const.i.tute the small-letter group. A sample of the sequence follows:

W cWc xWd Wdx cW cWd xWx Wxc dW cWx W2c Wxd xW dWc Wcd W2x Wc dWd Wcx cW2c Wd dWx Wdc cWcd Wx xWc W2d cWcx

As may be readily seen, the sequence proceeds in the same fas.h.i.+on as the a, t, r, small-letter sequence.

VII. Special Loop Extension used by the _Federal Bureau of Investigation:_

111 777.

--- to --- 111 777

The following is a partial sequence for filing this extension:

111 112 113 114 115 116 117 --- --- --- --- --- --- --- 111 111 111 111 111 111 111

121 122 123 124 125 126 127 --- --- --- --- --- --- --- 111 111 111 111 111 111 111

131 132 133 134 135 136 137 --- --- --- --- --- --- --- 111 111 111 111 111 111 111

141 142 143 144 145 146 147 --- --- --- --- --- --- --- 111 111 111 111 111 111 111

151 152 153 154 155 156 157 --- --- --- --- --- --- --- 111 111 111 111 111 111 111

161 162 163 164 165 166 167 --- --- --- --- --- --- --- 111 111 111 111 111 111 111

171 172 173 174 175 176 177 777.

--- --- --- --- --- --- --- etc., to --- 111 111 111 111 111 111 111 777

No matter how many of these divisions may be used, the order should remain the same; and no matter how many of these divisions are used, each individual group should be sequenced by:

VIII. _Final:_

Filed in numerical sequence from 1 out. For example, a.s.sume that there are 15 prints in a group having a final of 14. All of these should be filed together and followed by those prints in the same group having a final of 15, etc.

IX. _Key:_

All prints appearing in a designated final group are arranged by key in numerical sequence from 1 out. For example, a.s.sume that there are 5 prints in a group having a key of 14. All of these should be filed together and followed by those prints in the same group having a key of 15, etc.
