Page 299--The Beni Amer--The word Amer [Arabic] in this place must not be confounded with Amer [Arabic] another tribe of Harb. The damma [Arabic vowel] in [Arabic] is never p.r.o.nounced by the Arabians, who say Amr Ibn el Las, ([Arabic]) and not Amrou Ibn el Las, placing the damma [Arabic vowel] merely to distinguish the word from [Arabic] Omar.
