Although the two samples appear to be physically quite different,
the Ansarit material solid and hard and the Ghaiz specimen flaky,
there seems to be no doubt about their similarity by chemical
analysis, and it might be concluded, in both cases, that we are dealing
with a bituminous substance, petroleum residue, which has traversed
a bedding plane of the strata and travelled along the fault on its way
upwards from some oil-bearing stratum below. Unfortunately
neither specimens react to the solvent action of alcohol, petroleum
ether or benzol and do not even give a coloration, and thus, ac
cording to normal tests, neither sample can be regarded as a
petroleum residue at present. #
Mr. O. H. Little has mentioned the Bitumen from Lahia near
El Sidara (a specimen of pure black Bitumen) which assayed 96-00%
