A few notes (marked with inverted commas and with the signature S. F.) have been kindly furnished by a scientific friend.

"Ardito veramente alquanto, sanguigno, e quasi fiammeggiante."—Zanetti della Pittura Veneziana, Ven. 1771, p. 90. Warm as the flesh colour of the colourists is, it still never approaches a positive hue, if we except some examples in frescoes and other works intended to be seen at a great distance. Zanetti, speaking of a fresco by Giorgione, now almost obliterated, compares the colour to "un vivo raggio di cocente sole."—-Varie Pitture a fresco dei Principali Maestri Veneziani. Ven. 1760.

Ridolfi.

Zanetti, I. ii.

Two great authorities, divided by more than three centuries, Leon Battista Alberti and Reynolds, have recommended this subdued treatment of white. "It is to be remembered," says the first, "that no surface should be made so white that it cannot be made more so. In white dresses again, it is necessary to stop far short of the last degree of whiteness."—Della Pittura, I. ii., compare with Reynolds, vol. i. dis. 8.
