old timbers of mines. In these cases the zinc sulphide has probably
arisen from the reduction of sulphate by organic matter.

Localities for fine crystallized specimens are numerous. Mention may be
made of the brilliant black crystals from Alston Moor in Cumberland, St
Agnes in Cornwall and Derbyshire. Yellow crystals are found at
Kapnik-Banya, near Nagy-Banya in Hungary. Transparent yellow cleavage
masses of large size occur in limestone in the zinc mines at Picos de
Europa in the province of Santander, Spain. Beautiful isolated
tetrahedra of transparent yellow blende are found in the snow-white
crystalline dolomite of the Binnenthal in the Valais, Switzerland.

BLENHEIM (Ger. _Blindheim_), a village of Bavaria, Germany, in the
district of Swabia, on the left bank of the Danube, 30 m. N.E. from Ulm
by rail, a few miles below Hochstadt. Pop. 700. It was the scene of the
defeat of the French and Bavarians under Marshals Tallard and Marsin, on
the 13th of August 1704, by the English and the Austrians under the duke
of Marlborough and Prince Eugene. In consideration of his military
services and especially his decisive victory, a princely mansion was
erected by parliament for the duke of Marlborough near Woodstock in
Oxfordshire, England, and was named Blenheim Palace after this place.

The battle of Blenheim is also called Hochstadt, but the title accepted
in England has the advantage that it distinguishes this battle from that
won on the same ground a year previously, by the elector of Bavaria over
the imperial general Styrum (9-20 September 1703), and from the fighting
between the Austrians under Krag and the French under Moreau in June
1800 (see FRENCH REVOLUTIONARY WARS). The ground between the hills and
the marshy valley of the Danube forms a defile through which the main
road from Donauworth led to Ulm; parallel streams divide the narrow
plain into strips. On one of these streams, the Nebel, the French and
Bavarians (somewhat superior in numbers) took up their position facing
eastward, their right flank resting on the Danube, their left in the
under-features of the hilly ground, and their front covered by the
Nebel, on which were the villages of Oberglau, Unterglau and Blenheim.
The imperialist army of Eugene and the allies under Marlborough (52,000
strong) encamped 5 m. to the eastward along another stream, their flanks
similarly protected. On the 2nd-13th of August 1704 Eugene and
Marlbo
