Pyromorphite is pseudomorphous after galena, usually in 
crust-like masses, with parts of the cubic outlines visible, 
though at times the form of the pseudomorph is that of a com- 
plete cube. At Lone Elm pyromorphite occurs in botryoidal 
and stalactitic forms coated with cerussite crystals. Occa- 
sionally pyromorphite pseudomorphs after cerussite are found 
here. 
The localities are Lone Elm, Joplin, Granby, several lo- 
calities around Galena, at one mine in the Roaring Springs 
district, and also east of Duenweg. 
Barite; ‘“‘Tirr’’; ‘‘CRYSTALLIZED ZINC.’’ 
Observed forms: ¢c(001)OP; m(110) oP; a(100) “Po; 
d(102)4P ; u(101) Po. 
Barite occurs in tabular crystals flattened parallel to the 
basal plane. Occasionally small phantom crystals are found. 
The massive dendritic variety so common in the lead re- 
gion of southeastern Missouri has been found at a few places 
in the district. 
In color the barite varies from colorless or white to the 
bluish green so common for this mineral, a pale tint of the 
latter being the usual color. 
Anglesite. 
Observed forms: c(001)OP; b(100) ©Po; m(110) oP; 
O(011)P© ; \(104)4P@ ; d(102)4Po ; y(112) P2. 
Crystals of anglesite with the following combinations of 
forms were found at Galena: (1) O,m, y, c, b (figure 75) ; 
(2) m, d (figure 76) ; (8) m,1 (figure 77). The reflections 
were not in all cases good, but were sufficient to identify the 
forms. 
Anglesite is a comparatively rare mineral in the district. 
It was found by the writer at the Bonanza ground, northwest 
of Galena, and at the Mitchell shaft, on the Schermerhorn 
ground, west of Galena.
