It is not till about Balis, in lat.

36 deg., that this intention appears to be finally relinquished, and the convergence of the two streams begins.

The Euphrates at first flows nearly due east, but soon takes a course which is, with few and unimportant deflections, about south-east, as far as Suk-es-Sheioukh, after which it runs a little north of east to Kurnah.
The Tigris from Til to Mosul pursues also a south-easterly course, and draws but a very little nearer to the Euphrates.

From Mosul, however, to Samarah, its course is only a point east of south; and though, after that, for some miles it flows off to the east, yet resuming, a little below the thirty-fourth parallel, its southerly direction, it is brought about Baghdad within twenty miles of the sister stream.

From this point there is again a divergence.
