 The 21. measureth the 2d Section in a Sphere and Spheroid, which may be of use to measure the midle Zone of a Spheroid, cut by a Plane parallel to the axis; i.e. when the superfice of the liquor cuts the head of the Cask.

The 24th measureth right Cylindrick Hoofs, viz. Circular, Elliptick, Parabolick and Hyperbolick, and may be used for the measuring of Brewers leaning Vessels.

To these is added a Table of Squares and Cubes, very useful in finding the portions of a Sphere, Spheroid, Parabolick and Hyperbolick Conoides.
