The limits of Babylonia Proper, the tract in which the dominant power of the Fourth Monarchy had its abode, being almost identical with those which have been already described under the head of Chaldaea, will not require in this place to be treated afresh, at any length.

It needs only to remind the reader that Babylonia Proper is that alluvial tract towards the mouth of the two great rivers of Western Asia--the Tigris and the Euphrates--which intervenes between the Arabian Desert on the one side, and the more eastern of the two streams on the other.

Across the Tigris the country is no longer Babylonia, but Cissia, or Susiana--a distinct region, known to the Jews as Elam--the habitat of a distinct people.

Babylonia lies westward of the Tigris, and consists of two vast plains or flats, one situated between the two rivers, and thus forming the lower portion of the "Mesopotamia" of the Greeks and Romans--the other interposed between the Euphrates and Arabia, a long but narrow strip along the right bank of that abounding river.
