A. NESBIT has in the Press, "A TREATISE on PRAC-
TICAL ARITHMETIC," which he hopes will be found well
adapted to the real Business of Life. This Work has been in hand
a considerable time; and will be completed as soon as the Author's
other engagements afford him leisure.

Mr. NESBIT receives into his House a limited Number of
Boarders, for the purpose of Tuition. The terms of the School
and other particulars may be known by applying to Mr. NESBIT,
Oxford Street, Manchester.

A TREATISE

ON

PRACTICAL MENSURATION.

PART I.

Definitions, Problems, and Theorems, in Geometry.

GEOMETRY originally signified the Art of measuring the Earth, or any distance or dimensions upon or within it; but it is now used for the Science of Quantity, Extension, or Magnitude, abstractedly con◄ sidered.

GEOMETRICAL DEFINITIONS.

1. A point is considered as having neither length, breadth, nor thickness.

2. A line has length, but is considered as having neither breadth nor thickness.

3. Lines are either right, curved, or parallel.

4. A right or straight line lies wholly in the same direction between its extremities, and is the shortest distance between two points.

5. A curved line continually changes its direction between its extremities.
