It is seen thatthe ridges do not run in uninterrupted parallel lines, but in some placesa line stops, and forms a free end, while the two adjacent ridges close upbeyond it. In places, too, a ridge clearly branches, and forms a fork, andin one place in this print, but more frequently in some other cases, a smallbit of ridge is seen lying, all by itself, between two long ridges. This iscalled technically an island, and occurs many times in the thumb-printshown farther on (Figure 129). A fourth kind of ridge detail, not wellshown here, but possibly present in the poorly printed right lower portion,is an interruption or break, where a ridge comes to an end, but, instead ofbecoming discontinued, as in the case of a true end, continues again, leavinga short interval, or interruption, along its course. These four sorts of details, (1) ends, (2) forks, (3) islands, and (4) Text Appearing After Image: V^»-^ Figure 126.

Forks, by adding to the total count of the ridges in a certain area,appear where an element of a pattern broadens out, or runs over a convexsurface, and ends, which denote the loss of ridges, are found under theopposite circumstances, when a system of ridges contracts. Breaks andislands are seemingly accidental and without special significance, althoughthe presence of long strings of islands interpolated between two ridgesrather far apart, as are seen in Figure 129 below, may represent the ves- No Tivo Identical Finger Prints 315 tiges of a suppressed ridge, that never came to development because itwas not needed.
