ng to a stain of
limonite. Crystals from some other localities, notably from Monteponi
in Sardinia, are transparent and colourless, possessed of a brilliant
adamantine lustre, and usually modified by numerous bright faces. The
variety of combinations and habits presented by the crystals is very
extensive, nearly two hundred distinct forms being figured by V.
von Lang in his monograph of the species; without measurement of the
angles the crystals are frequently difficult to decipher. The hardness
is 3 and the specific gravity 6.3. There are distinct cleavages
parallel to the faces of the prism (110) and the basal plane (001),
but these are not so well developed as in the isomorphous minerals
barytes and celestite.

Anglesite is a mineral of secondary origin, having been formed by the
oxidation of galena in the upper parts of mineral lodes where these
have been affected by weathering processes. At Monteponi the crystals
encrust cavities in glistening granular galena; and from Leadhills,
in Scotland, pseudomorphs of anglesite after galena are known. At most
localities it is found as isolated crystals in the lead-bearing
lodes, but at some places, in Australia and Mexico, it occurs as large
masses, and is then mined as an ore of lead, of which the pure mineral
contains 68%.

ANGLI, ANGLII or ANGLES, a Teutonic people mentioned by Tacitus in
his _Germania_ (cap. 40) at the end of the 1st century. He gives no
precise indication of their geographical position, but states that,
together with six other tribes, including the Varini (the Warni of
later times), they worshipped a goddess named Nerthus, whose sanctuary
was situated on "an island in the Ocean." Ptolemy in his _Geography_
(ii. 11. Sec. 15), half a century later, locates them with more precision
between the Rhine, or rather perhaps the Ems, and the Elbe, and speaks
of them as one of the chief tribes of the interior. Unfortunately,
however, it is clear from a comparison of his map with the evidence
furnished by Tacitus and other Roman writers that the indications
which he gives cannot be correct. Owing to the uncertainty of these
passages there has been much speculation regarding the original home
of the Angli. One theory, which however has little to recommend it, is
that they dwelt in the basin of the Saale (in the neighbourhood of the
canton Engilin), from which region the _Lex Angliorum et Werinorum hoc
est Thuringorum_ is
