to the commencement of the concavity of the neck, where the 

 beading runs round. 



I remarked, that by adhering to regular proportional quan- 

 tities of 1 and 2, 3 and 5, 2 and 5, 7 and 5, 7 and 2, Sec, 

 and using elliptic disks or curves, very great beauties are 

 derived. 



A skeleton of the tazza in angles was drawn on a black 

 painted board, together with oval disks placed upon those lines, 

 which clearly demonstrated the whole system of the construc- 

 tion. The explanation of these various diagrams necessarily 

 involved a circumstantial description of each created figure, 

 which were thoroughly analysed. Quantity and variety were 

 particularly dwelt upon, as absolutely necessary to the produc- 

 tion of perfect beauty ; equalities being unfriendly to that sym- 

 metry which accords with nature. Some other diagrams were 

 drawn, to show the inelegant appearance of radiating lines from 

 ^e concave or convex half of an oval or an ellipse. Fig. 19 :

but by drawing another convex half of an oval, and placing those 

 lines as tangents, greater beauty was formed by the alternate 

 changes and varieties of inclination of each tangent. Fig. 20.

This was capable of an immediate adaptation to elegant vege-
