I must here remark that Tauk Kesra, the palace of the
Sassanian kings, is not built of Babylonian bricks, as has
been supposed; and that the masonry is strikingly inferior
to that of Babylon.

The same note to the curious and learned Memoir of M.
de Sainte Croix contains a discussion concerning the lati
tude and longitude of Hillah, and its distance from Bag
dad, by M. Beauchamp. Niebuhr gives the latitude of
Hillah 32° 28', which would make its distance from Bagdad
amount to 21f leagues of 25 to a degree. M. Beauchamp,
from an observation of the transit of Mercury over the
sun, on the 5th November, 1789, makes it 5 degrees to the
west of Bagdad, which he calls being very nearly under the
same meridian—" sous le m^me meridien a tres peu pres."
He is of opinion that the distance given by Niebuhr's
observation (22 leagues) is a little too much, because only
18 leagues are reckoned in performing the journey, the
whole of the way being over a desert as flat as a table. He
says that in two journeys he made from Badgad to Hillah
he counted 16^ hours ordinary pace of a caravan, Niebuhr
supposes 13 to 14 German miles, 13J of which would be just
224 leagues of 25 to the degree. From this distance, which
appears overrated, M. Beauchamp concludes that Niebuhr's
latitude is too small: his own observation gave 32° 40';
but he deducts 5' for the error of his instrument, which
error he did not ascertain, but only supposed—he does
not say why. This, he says, will be found to correspond
better with the reckoned distance. The latitude of Babylon
will then, according to him, be 32° 37'. He observes that
even if the rate of going of a horseman at a walk be
