, Position of the Confluence of the Zab and Tigris.
(Referred to at p. 134, Vol. ii.)
The following remarks are the result of observations made
by Mr. Rich during two previous voyages down the Tigris.
Abulfeda, and the Turkish geographer who follows him,
place Haditha and the confluence of the Zab and Tigris at
the distance of fourteen farsakhs, road distance, below
Mousul, Major Rennel makes it forty-two geographical
miles, direct distance, which is evidently too much. Olivier's
map, which is, I believe, drawn up from Beauchamp's au
thority, makes it ten leagues, or thirty geographical miles,
and Nimrod six leagues. I was exactly eight hours and
twenty minutes dropping down the river on a raft (in the
month of April) from Mousul to the mouth of the Zab,
cledi of all deductions and delays ; the river was then pretty
high, and the current strong.
For further particulars, I was four hours precisely from
a place one hour below Mousul to Hamam Ali. Hamam
Ali I know to be at the distance of five hours by land from
Mousul. Kara Koyunlee I also know to be three hours
from Mousul. 1 was two hours and twenty minutes by
^titci fiom the abo\e place j and just before I arrived at
•Kiird Koyunlee, I set the high old minaret of Mousul, which
bore N. 35 W., the supposed variation being eighty W.
From Hamam Ali, Nimrod bore S. 35 E. Nimrod,
which Beanchamp or Olivier's map makes six leagues
from Mousul, is, according to my information, just seven
hours' journey by land. I therefore make it on the map
