with traces of lime and bismuth. G-. of No. 1=3*36, both specimens were from Schneeberg, 

 Saxony. In a partial analysis v. Kobell obtained (1. c.) Mn 54-00, Co 4 "00, Cu 0-61, £l 23 00, 

 H 13.4. 



Gives Avater in the tube. Infusible, colors the flame carmine-red. With the fluxes reacts 

 for manganese ; with salt of phosphorus in R. F. gives reactions for copper and cobalt. 

 Soluble in muriatic acid with evolution of chlorine. 



Found associated with quartz in many localities in the Schneeberg mining district, also 

 occurs at Sayn, and near Siegen. Supposed to be a product of the decomposition of psi- 

 lomelane. The large percentage of alumina and its content of lithia distinguish it readily 

 from asbolite and lampadite. 



598 A. Luneburgite. C. Nollner, Ber. Ak. Miinchen, 1870, 291. 



This name has been applied by Nollner to a salt from Liineburg having the following com- 

 position : P 29-8, B 12-7, Mg 25 -3, H 32-2=100. It also contains 0"7 Fl. Nollner gives as 

 formula for this substance (2 Mg, II) P + Mg B + 7 H. No physical characters are stated. 



1 A. Maldonite. O. H. F. Ulrich, Contrib. to Mineralogy of Victoria, 1870, (pamphlet 

 32 pp. 8vo.). 



In small particles in quartz, cleavage apparently cubical. H. = l*5 — 2. G. =8-2—9-7? 

 (made on less than one grain of impure mineral). Color pinkish-white, but tarnishing on 

 exposure to copper-color and then black. Malleable. An assay by C. Newbery showed the 

 composition to be Au 64'5, Bi 35 5, or nearly Au- Bi. B. B. fuses easily ; on charcoal coats 

 the coal yellow and yields a globule of gold. 



From Nuggety Reef, Maldon.

Amorphous, also found in small apparently isometric crystals, perhaps pseudomorphic.

Blowpipe characters like cinnabar. Occurs at the Redington Mine, Lake Co., California, 

 with cinnabar, quartz and marcasite. It differs from cinnabar in its amorphous character, 

 in color, streak, specific gravity and lustre, while in these respects it is identical with 

 the black artificial mercuric sulphide of the laboratory. 



Milarite. A. Kenngott, Jahrb. Min., 1870, 81. 



Hexagonal. Occurring form a hexagonal prism with a plane of a hexagonal pyramid on 

 each angle, and a narrow termination of the lateral edges ; observed angle over a terminal 

 edge of the pyramid 144° 46J' (mean of results), and over a basal edge 74° 40' ; the latter 

 gives for the former, by calculation, 144° 42'. 



H.=5'5— 6. Lustre vitreous. Colorless to greenish, resembling the datholite crystals 

 from Bergen Hill. Brittle. B. B. in the closed tube becomes white and gives off water. 

 In the forceps fuses with intumescence to a white blebby glass. In salt of phosphorus slowly 

 but completely soluble to a colorless glass. A partial qualitative analysis gave evidence of 

 the presence of an alkali and besides probably lime. Kenngott considers it a zeolitic hydrous 

 silicate of alumina, lime, and soda, but on uncertain evidence. 



Found in Val Milar near Ruaras, Switzerland. 



503. Montcbrasite. Des Cloizeavx, C. R. lxxiii. 306, 1247. L. Moissenet, Ann. d. Mines, VI. 

 xx. 1 (1871). F. Pisani, C. R. lxxiii, 1479. F. von KobeU, Ber. Ak , Miinchen, Feb. 3, 1872. 



This supposed fluo-phosphate from Montebras in France has recently been shown by Pisani 

 and von Kobell to be identical with amblygonite. Des Cloizeaux found it to be triclinic, with 

 two cleavages giving 105" 44', and in the optical examination the bisectrix of the acute angle 

 was positive, while in the Hebron amblygonite it is negative. Analyses by Moissenet (1), 

 Pisani (2), and v. Kobell (3) afforded :
