DIA. XI.
Dia. [XI] represents the garment in a three-fourths circle and on a square of 20. The circle itself would make the vest too short, but it represents the correct run of the bottom.
Dia. 11.
DIA. XII.
Dia. [XII] represents the same as the foregoing in a three-fourths circle, but on a square of 17½, also the equilateral triangle of 35 numbers. Each of the Dia. [XI] and [XII] are one square cut from the center of a circle, and in order to make it as simple as possible the vest is again used. The bottom of the forepart is on the circle, but that would make a short vest, and for this reason the back shows 1½ longer.
Dia. 12.
