Appendix by Domeyko to his pests of Chili follows the 
fourth after an interval of two s. It contains much valuable 
and interesting matter, haat apg the description of the following 
new minerals : 
Daubreite. 6 ero. say In structure earthy and compact, in 
parts fibrous. H.=2°5. G.=6-4-6°5. Color yellowish to gray- 
ish-white. Opaque. a analysis gave Bi,O, 89°60, Cl 750, 
H,O 3°84(?), Fe,O, 0°72, which corresponds. to the formula 
i iCl,. 
Krénkite.—In ene eerie masses with coarse fibrous 
structure; probably triclinic. Cleavage distinct parallel to an 
edge o the prism. Color azure-blue, changing somewhat on

ol 
Phill ipite—Forms small irregular masses and bands in the 
same argillacous ochre in which the copper pyrites occurs, by the 
decomposition of which it has been forekads Structure putas 
sometimes compact; never prismatic like Kronkite. Color azu 
blue. Luster vitreous; translucent. Soluble in water, but oe 
fected by exposure to the air, Composition CuSO P#eS50 12+
