Limoges, may be referred to phosphate of 
manganese.—Ores of manganese :—radiated grey 
manganese, from Ihlefeld, &c. some varieties of 
which resemble the radiated antimony in the 
disposition of their acicular crystals ; foliated grey 
manganese; compact grey manganese of various 
forms, botryoidal, tubercular, reniform, &c.; 
earthy grey manganese, a remarkable variety of 
which is the black wad of Derbyshire and De¬ 
vonshire, which has the property of inflaming 
spontaneously when mixed with linseed oil. 
(Case 41.) In this and the two following cases 
are contained the ores of lead, the most common 
and useful of which is the galena or sulphuret of 
lead: the specimens here deposited include va¬ 
rious modifications of crystals, detached and 
grouped together, in combination with blende, 
pyrites and many other substances ; galena of 
various grain, massive and disseminated ; galena 
of corroded appearance, decomposed and rege¬ 
nerated ; the compact and specular variety, called 
slickenside by the Derbyshire miners.—With 
these are also placed specimens of the antimo- 
pial sulphuret of lead, or triple sulphuret of lead,
