All the phenomena observed indicate the plausibility of the theory
that the ores wore deposited from isolations due to uprising waters
dissolving out the antimony content from tho eruptive rocks, and
that these solutions deposited their burdens not only in clefts and
fissures, but also penetrated laterally into tho joints between the

strata whenever there occurred an impervious stratum checking the
downward flow of the solutions, and that also sometimes having
become stagnant, they dissolved tho underlying limestone and
replaced it by tho mineral burdens they carried.
Antimony ore is also found at Losnica.
FRANCE.
Tho greater part of the antimony deposits of Franco is found in
the Central Plateau.* They generally occur in tho form of veins,
most of which have more or lens boon exploited. At the Nados
mine, in Bourbonnais, the gangue is mainly quartz. At Bresnay,
canton Savigny, the deposit is formed of two veins, contained in tho
granite. Here the minerals are accompanied by a sort of white
micaceous granulite, analogous to that found at Magurkain Hungary,
and consist of quartz and stibnite, the latter being thinly covered
over with the oxide. (A.)
At Villeninge, in La ('rouses the antimony veins present an interesting
phase, in that they cut tho gray wacko of the Culm formation,
and in consequence their age can be very easily determined. South
