The greatest height of the ruins is about 100 feet; their construction is very rude and primitive, the date of some buildings being evidently as early as that of the most ancient structures of either Mugheir or Senkereh.
Sixty miles to the north-west of these ruins, still on the left or eastern bank of the Euphrates, but at the distance of thirty miles from its present course, are the remains of another city, the only Chaldaean ruins which can dispute, with those already described, the palm of antiquity.

They consist of a number of separate and distinct heaps, which seem to be the remains of different buildings, and are divided into two nearly equal groups by a deep ravine or channel 120 feet wide, apparently the dry bed of a river which once ran through the town.
Conspicuous among the other hillocks is a conical heap, occupying a central position on the eastern side of the river-bed, and rising to the height of about seventy feet above the general level of the plain.
Further on in this direction is a low continuous mound, which seems to be a portion of the outer wall of the city.

The ruins are of considerable extent, but scarcely so large as those at either Senkereh or Warka.

The name which now attaches to them is Niffer: and it appears, from the inscriptions at the place, that the ancient Semitic appellation was but slightly different.

This name, as read on the bilingual tablets, was Nipur; and as there can be little doubt that it is this word which appears in the Talmud as Nopher, we are perhaps entitled, on the authority of that treasure-house of Hebrew traditions, to identify these ruins with the Calneh of Moses, and the Calno of Isaiah.
About sixty-five miles from Niffer, on the opposite side of the Euphrates, and in a direction only slightly north of west, are the remains of the ancient Borsippa.
