66 Report of the President 



present Curator cannot, could not, assume or prepare its reali- 

 zation. This is a frank statement, frankly considered, frankly 

 presented. 



The collection has been enriched this year by additions of 

 very handsome minerals, while the crowding overflow, in the 

 drawers, offers convincing testimony to the increasing wealth 

 of its contents. A striking, possibly a unique, strip of Moun- 

 tain Leather from Korea (now attached to the north wall) ; a 

 large Amalgam from Mexico ; superb cubical Cuprite, partially 

 reduced to metallic Copper, from Arizona; some wonderfully 

 developed Pyrites, extraordinary in size, and rich in faces, from 

 Colorado; a Pollucite mass from Maine; a few exquisite Ru- 

 bellites from California; a polished translucent slab of Cali- 

 fornite (Vesuvianite) ; an Antimony mass (ioo pounds) from 

 Kern County, California (secured through the Director's 

 Fund) ; beautifully tufted Calamine from Colorado; a wonder- 

 ful Scheelite crystal from Sonora, Mexico; a Sphalerite slab, 

 crystallized, from Colorado; rich lemon brown crystals of 

 Barite in a large group from England ; immense Betafites from 

 Madagascar ; some large Halites from Stassfurt ; a very ornate 

 group of Apophyllite from Poonah, India, and a gem-mass of 

 Chrysoprase from California, are, amongst a great many other 

 additions (see Accessions), worthy of especial emphasis. 



The collection of "Unclassified Minerals," those commonly 

 found in the successive Appendices to Dana's "System of Min- 

 eralogy" or in publications more recent, has reached large pro- 

 portions and demands public exhibition. 



The perennial value of the Bruce Endowment is acknowl- 

 edged, the generosity of the General Appropriation, and the 

 helpful financial assistance of the Director. 



The additions mentioned above yield, upon analysis, the fol- 

 lowing result: 



Gifts and Exchanges 3,447 



Bruce Endowment 830 



General Fund 819 



The more costly specimens were secured with the Bruce 

 Fund, and in several instances the generous assistance of the 

 Director's Fund has proved invaluable.
