The design, your Lordship sees, is good, the colouring transparent, the drawing not amiss; - or to speak more like a man of science, and to measure my piece in the painter's scale, divided into 20 - I believe, my Lord, the outlines will turn out as 12, the composition as 9, the colouring as 6, the expression 13 and a half, and the design - if I may be allowed, my Lord, to understand my own design, and supposing absolute perfection to be 20, - I think it cannot fall short of 19.
