NEW ARRIVALS. 



Dr. Foote has just returned from a four mouths' collecting trip in Mexico 

 (Lower California and Sonora), California, Arizona, New Mexico and the South- 

 ern States. 



The most interesting locality visited was Santa Rosalia, near which are the 

 mines of the Boleo Mining Co. Dr. Foote remained here about three weeks se- 

 curing many very choice specimens of the species that are found only at this 

 locality. Such interesting specimens of the associations have never been secured 

 before and we doubt if they will be again. 



The most remarkable specimens were the beautiful peach blossom colored 

 Remingtonite and Sphaerocobaltite. The former has been absolutely unknown 

 since its description by Prof. J. C. Booth of the Philadelphia Mint, from a 

 locality in Maryland 32 years ago. The latter described 17 years ago is almost 

 equally rare. These two Carbonates of Cobalt make very charming microscopic 

 specimens, 50 c. to $7.50. Boleites in cubes, cubo-octahedrons, or twins, in 

 separate crystals on a gangue of Phosgenite, Atacamite, Bouglisite(?) Gypsum, 

 etc., at very low prices. Representative specimens, small, 5c. to 50c, good speci- 

 mens 25c. to $2.50, remarkably fine specimens, $2.50 to $10.00, microscopic 

 specimens, 10c. to 25c. Cumengite, simple crystals on Bouglisite and on 

 Phosgenite, 10c. to $5.00, microscopic specimens 10c. to 25c, twins on Bouglisite, 

 $1.00 to $10.00, twins detached, $1.00 to $5.00. These are the most remarkable 

 twins ever seen, being composed of six distinct individuals arranged in three dis- 

 tinct sets of interpenetrating twins. This makes a six-rayed ball, three of whose 

 points are up, however it may lie. Perfect twins are excessively scarce. 

 Atacamite from Boleo, 10c to $2.00, microscopic specimens, 10 to 15c The 

 Boleites and Cumengites make the most beautiful microscopic specimens 

 known. They have been preserved with sharp angles by being packed separately 

 as soon as found. The finest wire silver and argentite ever found in the U. S., 

 elongated octahedrons, $25 00. Brilliant pyrite covered with a veil of quartz, 

 from New Mexico, $20.00. Stalactites of purest white and pale green, some deli- 

 cately arborescent from the Copper Queen Mine, 50c to $3.00. These and Azur- 

 ites, Cuprites, Malachites, etc, secured by several weeks' work at Bisbee. The 

 finest Azurites and Chalcotrichites were secured at Morenci. Other lists will 

 follow.
