1867 W. Thomson & P. G. Tait Treat. Nat. Philos. I. i. §128 We may divide curved surfaces into Anticlastic and Synclastic. A saddle gives a good example of the former class; a ball of the latter.

1875 P. Frost Solid Geom. (ed. 2) I. 379 Any point of an ellipsoid is..a point..at which, if a tangent plane be drawn, the surface in the neighbourhood of the point lies entirely on one side of the tangent plane; such surfaces are called Synclastic.
