RARE AND BEAUTIFUL MINERALS. 



Cumengeite is probably the most beautiful and interesting species tliat 

 has been described for many years. The simple crystals we can furnish at 

 from 10c. to $5.00 each. 



Groups on a matrix of Bouglisite or in clay which can easily be washed 

 away, leaving perfect crystals, from 15c. to $7.50. 



The remarkably rare trillings which show three terminations pointing up- 

 ward, no matter how turned, can be furnished at from 50c. to $10.00 ; some- 

 what bi'oken crystals, which show the trilling well, 25c. to s5.00. 



M. Ctjmenge took the last train from San Francisco before the strike com- 

 menced and brought with him from Boleo all the Cumengeite, Boleite, Sphaero- 

 cobaltite. Eemingtonite, that had been found that had not previously been 

 secured by himself or Dr. Foote. These, like all previous lots, we purchased. 



Boleite in good cubes, cubo-octahedrons, etc., with vaiious associations 

 from So. 00 to 815.00. 



A Pamphlet of twenty pages, fine colored plate with over 35 figures by M. 

 Ctjmenge will be sent postpaid on receipt of 50 cents. 



Sphaerocobaltite, for seventeen years almost unknown, in fine crystals. 

 The specimens brought from Boleo by Dr. Foote were almost immediately 

 sold, but M. Ctjmenge secured three or four pieces, and good specimens can 

 be supplied at from S2.00 to S10.00; fragments, some showing crystals, 10c. 

 to $2.00. 



Remingtonite, unknown for forty-two years, some covered with Selenite, 

 50c. to $7.50 ; fragments 5c. to 50c. 



Herkimer County Quartz. W. M. Foote has just spent a number of 

 days at diis celebrated locality and secured the pick of four collections from 

 ten to twenty years old that had not been broken into before. Bemarkably 

 beautiful, pellucid crystals, some containing Dolomite, some cavities contain- 

 ing fluid in which bitumen rises and falls at the same time, crystals in the 

 matrix, charming clusters and other varieties, from 5c. to $10.00. 



Sulphohalite, is a new species described in this Journal, six years ago, 

 from material collected by Dr. Foote. The form described was dodecahe- 

 dral ; but material just examined chemically and crystallographically by Mr. 

 Brown of the Univ. of Pennsylvania, is octahedral and cubo-octahedral ; 

 only a few crystals were obtained. Price $5.00 to $10.00. 



Among other recent arrivals are the Bath Meteorite originally described by 

 Dr. Foote, Canon Diablo Meteorites reduced one half, gray Epidote, fine, 

 terminated crystals, Caswellite, Topaz from Utah, fine crystals, Leadhillite, 

 Sulphurs, Lanthanite, Parisite, Hiddenite remarkably clear crystal, etc., etc.
