phers. He abandoned the Alexandrine idea of a northern outlet, and asserted that the sea was completely enclosed.
His map makes it over twice as long from east to west as from north to south. Apparently, when he became convinced that the sea was not connected with the northern ocean, he supposed the so-called Caspian gulf to be also a

One, exemplified by Murchison in his paper on the Caspian, assumes that the ancients were essentially wrong, and that their geographical accounts are worth studying only as literature. The other, exemplified by Hum-
