A lady residing at Blackheath has in her possession a fine Jay, which displays instinct allied to reason and reflection in no ordinary degree. This bird is stated by a Correspondent, (A.T.) to repeat distinctly any word that may be uttered before. She can identify persons after having once seen them, and been told their names; the latter she will pronounce with surprising clearness. She has a strong affection for a goldfinch in the same apartment, the latter bird appearing to return this fondness by fluttering its wings and other demonstrations of delight. The Jay has also been seen playing with two kittens, while the old cat looked composedly on at their gambols. This bird is in beautiful plumage, and is about twenty years of age. She is well known to the residents of Blackheath and its vicinity. * * * * * ENTOMOLOGY. I have lately observed a curious fact, which I have never seen noticed in any book which has fallen in my way, viz. that it is the tail of the caterpillar which becomes the head of the butterfly. I found it hard to believe till I had convinced myself of it in a number of instances. The caterpillar weaves its web from its mouth, finishes with the head downwards, and the head, with the six front legs, are thrown off from the chrysalis, and may be found dried up, but quite distinguishable, at the bottom of the web. The butterfly comes out at the top. Is this fact generally known?--_Corresp. Mag. Nat. Hist._ * * * * * THE RIVER TINTO. The river Tinto rises in Sierra Morena, and empties itself into the Mediterranean, near Huelva, having the name of Tinto given it from the tinge of its waters, which are as yellow as a topaz, hardening the sand and petrifying it in a most surprising manner. If a stone happen to fall in, and rest on another, they both become in a year's time perfectly united and conglutiated. This river withers all the plants on its banks, as well as the roots of trees, which it dyes of the same hue as its waters. No kind of verdure will flourish where it reaches, nor any fish live in its stream. It kills worms in cattle, when given them to drink; but in general no animals will drink out of the river, except goats, whose flesh, nevertheless, has an excellent flavour. These singular properties continue till other rivulets run into it, and alter its nature; for when it passes by Niebla, it is not different from other rivers. It falls into the Mediterranean six leagues lower down, at the town of Huelva, where it is two leagues broad, and admits of large vessels, which may come up the river as high as San Juan del Puerto, three leagues above Huelva.--_From a Correspondent._ * * * * * SPIRIT OF THE PUBLIC JOURNALS * * * * * THE GALLEY SLAVES.
