Rh dividing the two lower divisions into three equal parts, two of which give its height, and the original line a b the width at its base, fig. 13. The third division gives the height of the finial which is fixed on the gable at the intersections of the inner and outer lines of the coping, fig. 14.

The remaining figures refer to the drawing of the finial. The last fig. is to be drawn again, fig. 15, and the length a b set off from the apex downward, which gives the top of the large foliage, and its width is to be made equal to a b. This width is to be divided into three parts, and one of these parts set off downward for the depth of the foliage. The upper foliage is found by taking the distance between the outer square and the next fig. 4; and setting it from the point downwards, marks the upper line of the foliage, which is to be made equal in width to the inner square of fig. 4, and its depth one-third of its width. The same distance and thickness must be set off below the large foliage for the neck-moulding, the width of which is to be equal to the second square in fig. 4.

The next, fig. 16, shews the method of laying off the crockets. The distance below the neck-moulding is to be divided into six parts, and on these the thickness and projection of crockets is set off from the plan, fig. 7. The next figures shew the plan, shaft, and spire of the pinnacle complete without the working lines, and the treatise concludes by directing the spire to be set on the shaft, and "it is then a perfect pinnacle carried up from the foundation."
