Of the DORICK ORDER.

in 5 Parts, and of the upper Part divided in 3,turned up. The Projection of the Plinth andCornice before the Upright of the Dado, is (asbefore observed in the Tuscan Order) always equalto the Height of the Mouldings on the Plinth,which here at m n, being divided in 4 Parts, theProjections of the Members in the Cornice, andBase are determined, as exhibited by the perpen-dicular dotted Lines.

P R O B. V. To proportion the Heights of the prin-cipal Parts of the Dorick Column, Fig. I. PI. III.

(1.) Divide si the Height of the Column in-to 8 Parts, and take 1 Part, for the Diameter ofthe Column at its Base : Therefore note, that theHeight of the Dorick Column is 8 Diameters.(1.) The Height of the Dorick Base and Capitalare each Half a Diameter, as those of the Tuscan.

P ROB. VI. To proportion the Heights of the Baseof the Dorick Column.

Divide fh, Fig. II. Plate III. in 3 Parts, thelower 1 Part is the Height of the Plinth T, andi of the Middle x, of the lower Torus S. Halfthe upper 1 Part, is the Height of the upper To-rus O, and the Remains between the two Torus’sbeing divided in 6 Parts, give the upper and low-er, to the two Fillets P and R, and the Middle 4to the Scotia The Height of the Cincture Nis half of the Height of the upper Torus.

P R O B. VII. To proportion the Heights of theDorick Capital.

Divide a h the Height of the Capital, Fig. II.Plate III, into 3 Parts, and f the upper i, into3 give the upper 1 to the Fillet A, the other ato the Cima reverfa B, and the other ± Part tothe Abacus C. Divide the Middle Part in 3, givethe upper x to the Ovolo D, and the other 1 toan Astragal and Fillet, or Fillet and Caveto, orCima reverfa, or to three Annulets, at Pleasure.The Height of the Hypotrachelium G, or Neckof tire Capital, is the lower 1 Part, and the Heightof the Astragal \ thereof, as before in the Tuscan,The Shaft of this Column is diminished f at itsAstragal in Manner aforesaid.

PR OB. VIII. To determine the Projections of theMembers of the Base of the Dorick Column.

(1.) Divide the Semidiameter r 3, in 3 Parts,and turn out 1 Part from i to k , for the Projectionof the Plinth, before the Upright of the Column,(x.) Divide the Projection k i, in 4 Parts, the firstone and a half, terminates the Projection of theFillet R ; and x Parts and half, the Centre of theupper Torus O, and Cincture M.

P R O 6. IX. To describe the Scotia Q^at large,as at g ; Plate III.

Divide its Height in 3 Parts, and set one Part,from the second Part towards the Right Hand ;then the Points * * are the Centers on which theScotia may be described as required.

PROB.X. To determine the Projections of the Mem-bers of the Dorick Capital . Fig. II. Plate III.

Divide the Semidiameter of the Column at itsAstragal on its Abacus, into 2 Parts, and turnout 1 Part for the .Projection of the Abacus ■,which divide in 4 Parts, and terminate the Pro-jections of the Members, as exhibited by thedotted perpendicular Lines. The Projection ofthe Astragal H I, is determined the same, as thatof the Tuscan Order.

P R O B. XI. To proportion the Heights of theprincipal Parts of the Dorick Entablature , PlateIV.

Divide a b, the given Height into 8 equalParts, give 2 to the Architrave M N O P, 3 tothe Freeze L, and 3 to the Cornice.

PR OB. XII. To proportion the Heights of theMembers of the Dorick Architrave.

Divide the upper one Part of the Architrave in3, the upper 1, is the Height of the Tenia M,and the lower x Parts, divided in 3 Parts, theupper 1 Part is the Height of the Fillet N, andthe next 3 Parts of the Gutta’s or Drops O.

PR OB. XIII. To proportion the Heights of theMembers of the Dorick Cornice.

Divide the two upper Parts of the Height ofthe Cornice into 3 Parts, and the upper 1, in 4Parts; give the upper 1 to the Regula A, and^he other 3 to the Caveto or Cima recta B. Di-vide
