or TEHRIS, a town of Persia, and capital of Aderbeitzan. It was formerly the capital of Persia, and is now the most considerable next to Isfahan; for it contains 15,000 houses, besides many separate shops, and about 200,000 inhabitants. It is about five miles in circumference, and carries on a prodigious trade in cotton, cloth, silks, gold and silver brocades, fine turbans, and shagreen leather. There are 350 caravanserais, and 250 mosques. Some travellers suppose it to be the ancient Ecbatana; but of this there is no certainty. It is seated in a delightful plain, surrounded with mountains, from whence a stream issues, which runs through the city. E. Long. 47. 50. N. Lat. 38. 18.
