Frontpiece. The Gauger’s Practice: OR, A Compendious Way of Gauging Brewers Tuns; and the Gauging of CASKS, according to the true Rules of Art. WITH A Table of CYLINDERS in Ale-Gallons, in Centesimal Parts: Calculated to every Tenth of an INCH in Diameter and Dept. By George Ward, Philomath. The Second Edition, Whereunto is Added, The Elements of Gauging; OR, A Solution of all the necessary Problems in Gauging; with the Reasons of them, Geometrically demonstrated. By JAMES LIGHTBODY, P.M. London: Printed for W. Battersby, and Sold by Robert Battersly at Staple-Inn-Gate, next the Barrs in Holbourn, 1697.

p. 20 In Geometry he ought to know the Three forts of QUANTITY; that is, a LINE, a SUPERFICIES, and a SOLID.

A Line hath length, but no breadth; a Superficies hath Length and Breadth, but no Depth; a Solid hath Length, Breadth and Depth. And there is no kind of Quantity but is measurable by some common Measure, as a Line is measured by a Line of Inches, or Feet, etc. a Superficies is measur’d by a Superficies, as one Square Inch, or One Square Foot, etc. and a Solid is measured by a Solid, as one Cubical Inch, or one Cubical Foot, etc.

So when it is known, how many Inches or Feet are contained in a Line, the length of that Line is said to be known; and when it is known how many Square Inches or Feet are contain’d within any Superficies, the Content, or Area of that Superficies is said to be known; and also when it is known how many Solid or Cubical Inches are contain’d in any Solid, the Content of that Solid is likewise said to be known.

And likewise ‘tis convenient, before the Entring upon Gauging, first to understand the Measures of BEER, ALE and WINE now used in England, and to know what the Primitive Measure is, and its Capacity, that thereby may be known the Names and Capacities of those which are Derivative.

p. 21 First, Note, That the Beer or Ale-Gallon, now in use, contains 282 Cubical Inches, and the Wine Gallon contains 231 Cubical Inches; also the Corn Gallon, or Dry Gallon, contains 272¼ Cubical Inches.

A Table of Beer-Measure

p. 24 A Table of the Dimensions of several Wine and Beer Vessels used in England, with their Content in Gall. and Cubical Inches

p. 25 To find the Area, or Content of a Cooler, Back, or Tun, in the Form of a Square.

The Rule is,

Multiply the side into itself (which is call’d the Squaring of a Number) the Product divide by 285, or Multiply by .0035461, and the Quot. Or Product is the Area, or Content in Ale Gallons at one inch in Depth.

To make a Multiplier to serve instead of a Divisor, divide an Unit by the Divisor, and the Quot. Will be the Multiplier. Thus this Number was made, viz. .0035461

According to the Rule, Multiply the side 108, by 108, and the Product is 11664, which divide by 282, and the Quot. Will be 41 Gallons. But in the Division,m if a Fraction remain, as in this Example, add 3 Cyphers to it, and still divide by 282 and the Quot. Will be the thousandth parts of a Gallon

A Square is a Figure consisting of Four equal sides, and Four Right Angles, like the Face of a Dye, or this Figure, and a Cube is a Solid erected on Such a Plain or Base.
