sum of the greatest and least depths of the malt; then 4070.44 x 27 = 109901.88; and 109901.88 ÷ 2738 40.138, the content in malt bushels.

EXAM. 4.

Here 65o = 4225, the square of the diameter of

PROBLEM XXIII.

To find the content of a cylindrical ungula or hoof,

when its base is less than a semicircle.

96 × 2 192

=243, the cube of the height

divided by twice the chord; then 2300 + 243 = 2543 square inches, the area of the base of the hoof.

100

Also,

3650 36 = 14, the difference

between half the diameter of the vessel and the versed

sine of the hoof's base; and 2543 x 14 35602, the area of the base multiplied by the said difference. 221184

Again 485 x = 110592 x } = 3

73728, two thirds of the cube of half the chord; and

73728

35602 = 38126; then 38126 x

= 38126 x 3 =

108 36

114378, the content in cubic inches; hence 114378 231 = 495.142, the content in wine gallons.

PROBLEM XXIV.

[blocks in formation]

To find the content of a cylindrical ungula, when its base is greater than a semicircle.

EXAM. 2.

By Rule 2, Prob. XV., Part IV., we have 64 ÷ 80.8, the tabular height; then by Note 2, of the same Problem, 1 and the Area Seg. answering to .2 is .111823, which being taken from .785398,

.8

2;

leaves .673575, the Area Seg. corresponding to .8; hence 673575 x 80% = .673575 x 6400 = 4310.88, the area of the ungula's base, in square inches.

Also, 64 40 = 24, the difference between the versed sine of the ungula's base and half the diameter of the vessel; and 4310.88 x 24 = 103461.12, the area of the base multiplied by the said difference.

Again, 325 x = 32768 x = %

21845.33, two thirds of the cube of half the chord; and 103461.12 + 21845.333 = 125306.453; then 92 11528193.676

125306.453 X = 64

64

= 180128.026,

the content of the ungula, in cubic inches; hence 180128.026 ÷ 231 = 779.775, the content in wine gallons.

PROBLEM XXVI.

To find the content of a pyramidical ungula, or the quantity of liquor contained in a vessel in the form of the frustum of a square or rectangular pyramid. when it is placed in such a position that the liquor just covers the bottom, and rises up three of the sides in an oblique direction, forming a figure that is called a cuneus or wedge.

EXAM. 2.

Here 30 x 2 + 33 = 60 + 33 = 93, twice the length of the base added to the length of the upper 93 x 27 x 22 2511 x 22

edge of the liquor; then

PROBLEM XXVII.

To find the content of a conical ungula, or the quantity of liquor contained in a vessel in the form of the frustum of a cone, when it stands upon its greater base, and in such a position that the liquor just covers the whole of its bottom.

EXAM. 2.

Here √82.6 × 58.7 = √ 4848.62 = 69.62, the the mean proportional between the diameters; and 4848.62 x 69.62 69.62 337560.9244, the product of the two diameters multiplied by the mean proportional between them.

PROBLEM XXVIII.

To find the content of a conical ungula, or the quantity of liquor contained in a vessel in the form of the frustum of a cone, when it stands upon its less base, and in such a position that the liquor just covers the whole of its bottom.

EXAM. 2.

Here 67.8 x 42.3 = √2867.94 = 53.553, the mean proportional between the diameters; and 2867.94 x 53.553 = 153586.79082, the product of the two diameters multiplied by the mean proportional between them.

Also 42.35 = 75686.967, the cube of the 153586.79082-75686.967 67.8 42.3
