being furnished with a microscope to look at them. It would be idle for him to look at them without one. He couldn't appreciate the delicate lines and the expression of the faces. If you go to Parma, they will show you a gem once worn on the finger of Michel Angelo, of which the engraving is two thousand years old, on which there are the figures of seven women. You must have the aid of a glass in order to distinguish the forms at all. I have a friend who has a ring, perhaps three quarters of an inch in diameter, and on it is the naked figure of the god Hercules. By the aid of glasses you can distinguish the interlacing muscles, and count every separate hair on the eyebrows. Layard says he would be unable to read the engravings on Nineveh without strong spectacles, they are so extremely small. Rawlinson brought home a stone about twenty inches long and ten inches wide, containing an entire treatise on mathematics. It would be perfectly illegible without glasses. Now, if we are unable to read it without the aid of glasses, you may suppose the man who engraved it had pretty good spectacles. So the microscope, instead of dating from our time, finds its brothers in the Books of Moses--and these are infant brothers." Speaking of colors, he said, "The burned city of Pompeii was a city of stucco. All the houses are stucco outside, and it is stained with Tyrian purple--the royal color of antiquity. But you can never rely on the name of a color after a thousand years, so the Tyrian purple is almost a red. This is a city of all red. It had been buried seventeen hundred years, and, if you take a shovel now and clear away the ashes, this color flames up upon you a great deal richer than anything we can produce. You can go down into the narrow vault which Nero built him as a retreat from the great heat, and you will find the walls painted all over with fanciful designs in arabesque, which have been buried beneath the earth fifteen hundred years; but when the peasants light it up with their torches, the colors flash out before you as fresh as they were in the days of St. Paul. Page, the artist, spent twelve years in Venice, studying Titian's method of mixing his colors, and he thinks he has got it. Yet come down from Titian, whose colors are wonderfully and perfectly fresh, to Sir Joshua Reynolds, and, although his colors are not yet a hundred years old, they are fading; the color on his lips is dying out, and the cheeks are losing their tints. He did not know how to mix well. And his mastery of color is as yet unequaled.... The French have a theory that there is a certain delicate shade of blue that Europeans cannot see. In one of his lectures to his students, Ruskin opened his Catholic mass-book and said, 'Gentlemen, we are the best chemists in the world. No Englishman ever could doubt that. But we cannot make such a scarlet as that, and even if we could, it would not last for twenty years. Yet this is five
