Subordinate to either one of these the quinary may and often does appear.

In its structure the quinary is the simplest, the most primitive, of the natural systems.

Up to this point the Greenlander's scale is almost purely quinary.

The foregoing examples will show with considerable fulness the wide dispersion of the quinary scale.
