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). V^»-^ Figure 126. Print of the right middle fingerof Bangor Billy; an Ulnar Loop with a 6-ridgecount.

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.
