    Henry was asked point blank if the 1024 bundle system was his own invention, and he firmly announced that it was; in the past, writers have tended to support Henry’s claim. They point out that as the English official © 2001 by CRC Press LLC 0923Ch01Frame Page 27 Monday, May 14, 2001 1:34 PM in charge he undoubtedly supported and encouraged his staff and should therefore be responsible for the innovation they suggested. In a letter dated May 10, 1926, Henry wrote to a correspondent concerning Haque: I wish to make it clear that, in my opinion, he contributed more than any other member of my staff and contributed in a conspicuous degree to bringing about the perfecting of a system of classification that has stood the test of time and has been accepted in most countries.

    On the hypothenar eminence, toward the radial margin of the metacarpal, a larger loop is often observed where the rugae and sulci going out from the margin are again reflected onto it. Sometimes an elliptical whorl is seen on this eminence. Fingerprint Classification A major step forward in the use of fingerprints was a method of classification that enabled fingerprint forms bearing differing patterns to be placed in a certain order, thus enabling the search area to be minimized. If a classification system did not exist, and a person gave a wrong name, each set of fingerprint forms would have to be examined to discover the correct identity of the offender; the person would obviously not be traced by doing an alphabetical check.

    A description of the problem-solving techniques employed in each task in the evaluation and identification processes is essential for an understanding of the scientific methodology of this forensic discipline: the conceptualization of the problems encountered, the formulation of the data observed, and the logic that must be applied to make the decisions necessary in solving each problem encountered in establishing identity. Many experienced latent print examiners may scoff at any attempt to thoroughly examine the thought processes involved in the evaluation and identification of latent prints.
