Some animals are held in universal dread by others, and not the least terrible is the effect produced by the rattle-snake. Mr. Pennant says, that this snake will frequently lie at the bottom of a tree, on which a squirrel is seated. He fixes his eyes on the animal, and from that moment it cannot escape: it begins a doleful outcry, which is so well known that a passer by, on hearing it, immediately knows that a snake is present. The squirrel runs up the tree a little way, comes down again, then goes up and afterwards comes still lower. The snake continues at the bottom of the tree, with his eyes fixed on the squirrel, and his attention is so entirely taken up, that a person accidentally approaching may make a considerable noise, without so much as the snake's turning about. The squirrel comes lower, and at last leaps down to the snake, whose mouth is already distended for its reception. Le Vaillant confirms this fascinating terror, by a scene he witnessed. He saw on the branch of a tree a species of shrike trembling as if in convulsions, and at the distance of nearly four feet, on another branch, a large species of snake, that was lying with outstretched neck and fiery eyes, gazing steadily at the poor animal. The agony of the bird was so great that it was deprived of the power of moving away, and when one of the party killed the snake, it was found dead upon the spot--and that entirely from fear--for, on examination, it appeared not to have received the slightest wound. The same traveller adds, that a short time afterwards he observed a small mouse in similar agonizing convulsions, about two yards from a snake, whose eyes were intently fixed upon it; and on frightening away the reptile, and taking up the mouse, it expired in his hand. SECOND SIGHT. About the year 1725, the marvellous history of a Portuguese woman set the whole world of science into confusion, as will be found by referring to the "Mercure de France." This female was said to possess the gift of discovering treasures. Without any other aid than the keen penetration of her eyes, she was able to distinguish the different strata of earth, and pronounce unerringly upon the utmost distances at a single glance. Her eye penetrated through every substance, even the human body; and she could discern the mechanism, and circulation of all animal fluids, and detect latent diseases; although less skilful than the animal magnetisers, she did not affect to point out infallible remedies. Ladies could learn from her the sex of their forthcoming progeny. The King of Portugal, greatly at a loss for water in his newly built palace, consulted her; and after a glance at the spot, she pointed out an abundant spring, upon which his Majesty rewarded her with a pension, the order of Christ, and a patent of nobility.
