What curvature is to lines, gradation is to shades and colors.

I might just as well have suspected the girl of a curvature of the spine.

Slight inequality of curvature in meridians of right cornea.

The place had a curvature like that of the seats in a theatre.

Curvature of the spine is more common than is usually thought.

On the other hand, the curvature of the seas is a no less certain proof.

He adds that what curvature is to lines, so is gradation to shades and colours.

The points at which the curvature vanishes are “points of inflection.”

It is seen that the curvature is greatly increased (Fig. 114).

This center is called the center of curvature, while the radius of the sphere R, is the radius of curvature.
