Arcuation :: Arcuation (n.) The act of bending or curving; incurvation; the state of being bent; crookedness.

Umbilicus :: Umbilicus (n.) A point of a surface at which the curvatures of the normal sections are all equal to each other. A sphere may be osculatory to the surface in every direction at an umbilicus. Called also umbilic.

Curvature :: Curvature (n.) The amount of degree of bending of a mathematical curve, or the tendency at any point to depart from a tangent drawn to the curve at that point..

Incurvated :: Incurvated (imp. & p. p.) of Incurvat.

Fair :: Fair (superl.) Without sudden change of direction or curvature; smooth; fowing; -- said of the figure of a vessel, and of surfaces, water lines, and other lines..

Anticlastic :: Anticlastic (a.) Having to opposite curvatures, that is, curved longitudinally in one direction and transversely in the opposite direction, as the surface of a saddle..

Ophthalmometer :: Ophthalmometer (n.) An instrument devised by Helmholtz for measuring the size of a reflected image on the convex surface of the cornea and lens of the eye, by which their curvature can be ascertained..

Incurvate :: Incurvate (a.) Curved; bent; crooked.

Devexity :: Devexity (a.) A bending downward; a sloping; incurvation downward; declivity.

Spherometer :: Spherometer (n.) An instrument for measuring the curvature of spherical surface, as of lenses for telescope, etc..

Curvate :: Curvate (a.) Alt. of Curvate.

Aplanatic :: Aplanatic (a.) Having two or more parts of different curvatures, so combined as to remove spherical aberration; -- said of a lens..

Chicken-breasted :: Chicken-breasted (a.) Having a narrow, projecting chest, caused by forward curvature of the vertebral column..

Recurvity :: Recurvity (n.) Recurvation.

Curvature :: Curvature (n.) The act of curving, or the state of being bent or curved; a curving or bending, normal or abnormal, as of a line or surface from a rectilinear direction; a bend; a curve..

Apophyge :: Apophyge (n.) The small hollow curvature given to the top or bottom of the shaft of a column where it expands to meet the edge of the fillet; -- called also the scape.
