has two vibrating tongues of wood, and is beaten with sticks that are smeared with an elastic gum obtained from the milky juice of plants; the yotl-bells of the Aztecs, that are hung in clusters like grapes; and a huge cylindrical drum, covered with the skins of great serpents, like the one that Bernal Diaz saw when he went with Cortes into the Mexican temple, and of whose doleful sound he has left us so vivid a description. The fantastic character of these instruments fascinated him, and he felt a curious delight in the thought that Art, like Nature, has her monsters, things of bestial shape and with hideous voices. Yet, after some time, he wearied of them, and would sit in his box at the Opera, either alone or with Lord Henry, listening in rapt pleasure to "Tannhäuser," and seeing in that great work of art a presentation of the tragedy of his own soul.
On another occasion he took up the study of jewels, and appeared at a costume ball as Anne de Joyeuse, Admiral of France, in a dress covered with five hundred and sixty pearls. He would often spend a whole day settling and resettling in their cases the various stones that he had collected, such as the olive-green chrysoberyl that turns red by lamplight, the cymophane with its wire-like line of silver, the pistachio-colored peridot, rose-pink and wine-yellow topazes, carbuncles of fiery scarlet with tremulous four-rayed stars, flame-red cinnamon-stones, orange and violet spinels, and amethysts with their alternate layers of ruby and sapphire. He loved the red gold of the sunstone, and the moonstone's pearly whiteness, and the broken rainbow of the milky opal. He procured from Amsterdam three emeralds of extraordinary size and richness of color, and had a turquoise de la vieille roche that was the envy of all the connoisseurs.
He discovered wonderful stories, also, about jewels. In Alphonso's "Clericalis Disciplina" a serpent was mentioned with eyes of real jacinth, and in the romantic history of Alexander he was said to have found snakes in the vale of Jordan "with collars of real emeralds growing on their backs." There was a gem in the brain of the dragon, Philostratus told us, and "by the exhibition of golden letters and a scarlet robe" the monster could be thrown into a magical sleep, and slain. According to the great alchemist Pierre de Boniface, the diamond rendered a man invisible, and the agate of India made him eloquent. The cornelian appeased anger, and the hyacinth provoked sleep, and the amethyst drove away the fumes of wine. The garnet cast out demons, and the hydropicus deprived the moon of her color. The selenite waxed and waned with the moon, and the meloceus, that discovers thieves, could be affected only by the blood of kids. Leonardus Camillus had seen a white stone taken from the brain of a newly-killed toad, that was a certain antidote against poison. The bezoar, that was found in the heart of the Arabian deer, was a charm that could cure the plague. In the nests of Arabian birds was the aspilates, that, according to Democritus, kept the wearer from any danger by fire.
The King of Ceilan rode through his city with a large ruby in his hand, as the ceremony of his coronation. The gates of the palace of John the Priest were "made of sardius, with the horn of the horned
