This contains the Proportions of the _Jonick_ Order and the _Attick_ Base: A is the Plinth of the _Attick_ Base, which is the third part of the whole Base, of which the upper part is the fourth part of what remains after the Plinth is taken; the inferiour part is half of what remains, and the other half is the _Scotia_. C D is the Plinth of the Jonick Base, which is the third part of the height of the whole Base. E is the Thorus which contains three parts of seven, into which is divided what remains, the other four being for the two _Scotia's_, and the two Astragals, which are betwixt the Thorns and the Plinth. F is the Capital, whose Proportion is explained in the eighth Table. G, H, I, K is the Architrave, which has four parts, _viz._ the Face marked G; the second marked H; the third marked I, and the _Cymatium_ or _Simaise_, marked K; L is the Frise. M, N, O, P, Q is the Cornice. M is the first _Cymatium_; N is the Dentil; O is the second _Cymatium_; P is the Crown with its little _Cymatium_ or _Simaise_. This Table relates to _pag._ 101. [Illustration: _Plate VII_] The EXPLICATION Of the EIGHTH TABLE. This contains the Proportions of the Ionick Capital, of which only half is seen here: A B is the half of the breadth of the Abacus, which is regulated according to the breadth of the bottom of the Column, of which one half is marked B 18; for the bottom of the Column being divided into 18, 19 are allowed to the Abacus: A C is the _Retreat_ which must be made of the Corner A, of the Abacus inwardly, to draw the Line C D, which must regulate the _Eye_ of the _Volute_ over which it must cross as it passes. To make this _Retreat_ we must take one part and a half of twelve, into which is divided the height or thickness, E F, of the whole Capital, which height is equal to half the breadth of the Abacus. This height, marked C D, is divided into nine parts and a half, of which one and a half is given to the _Abacus_, and four and a half from the Abacus to the middle of the _Eye_, which is traversed by the line G H; the Figures 1, 2, 3, 4, mark the four Centers of the first four quarters of the Volute; the four second quarters, and the four third (for the Volutte has twelve) are taken in the Diagonal 1, 3, and 2, 4. H, I, is the Astragal at the top of the Pillar which answers the _Eye_ of the Volute. K K is the Egg or _Echinus_; L is the Axis of the Volutes; M M is the ceinture of the lateral part of the Volutes. This relates to _pag._ 103.
