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

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