Page 98 - The classification of the description must be such that, on the arrest of an old offender who gives a false name, his record may be found readily and with certainty.

Page 33 - ... 22 CENTRAL POCKET LOOPS. It frequently happens in patterns of the Loop type that the ridges immediately about the core deviate in course from the general course of the other ridges. Such impressions may therefore be said to possess features which require their being defined as Loops in respect of the majority of their ridges and Whorls in respect of the appearance of the few ridges which occupy a space immediately about the centre, a delta more or less faintly defined having in consequence made...
