What is "ridges"

Usage examples of "ridges".

The ridge count referred to as such in connection with the tented arches possessing ending ridges and no recurve is obtained by imagining that the ending ridges are joined by a recurve only for the purpose of locating the core and obtaining a ridge count.

Nor was there any way around the ridges into the valley on the other side.

These ridges have definite contours and appear in several general pattern types, each with general and specific variations of the pattern, dependent on the shape and relationship of the ridges.

The outlines of the ridges appear most clearly when inked impressions are taken upon paper, so that the ridges are black against a white background.

Impressions may be made with blood, dirt, grease or any other foreign matter present on the ridges, or the saline substance emitted by the glands through the ducts or pores which constitute their outlets.

Lines A and B, which have been emphasized in this sketch, are the type lines, starting parallel, diverging at the line C and surrounding the pattern area, which is emphasized in figure 12 by eliminating all the ridges within the pattern area.

In such a case the two forks become the two innermost ridges required by the definition.

This would be equally true whether the ridges were connected with one of the type lines, both type lines, or disconnected altogether.

In the loop type pattern the ridges intervening between the delta and the core are counted.

In the event there is a bifurcation of a ridge exactly at the point where the imaginary line would be drawn, two ridges are counted.

Fragments and dots are counted as ridges only if they appear to be as thick and heavy as the other ridges in the immediate pattern.

There are no ridges intervening between the delta, which is formed by a bifurcation, and the core.

An imaginary line drawn between the two deltas must touch or cross at least one of the recurving ridges within the inner pattern area.

An imaginary line drawn between the two deltas must not touch or cross any of the recurving ridges within the inner pattern area.

Underneath every pattern there are ridges running from one side to the other, so that if it were not excluded every pattern but the plain arch would be an accidental whorl.
