No. 2. 



HE Journal presents with this issue a general 

 Guide Leaflet to the Halls of Minerals which will 

 be found of great assistance by persons visiting 

 and inspecting the collections therein. Just be- 

 fore Thanksgiving Day last year the hall was 

 opened, first to members of the Museum and their friends and 

 afterwards to the general public, with the great acquisition of 

 the Bement mineral collection all in place. This collection had 

 long had the reputation of being the finest private collection of 

 exhibition specimens of minerals in the world, so that the 

 Museum authorities felt that they were indeed to be con- 

 gratulated when a munificent friend of the institution some- 

 what more than a year ago presented the whole to the Museum, 

 including the magnificent collection of meteorites, which is one 

 of the largest assemblages in existence of those interesting 

 visitors from space. Practically nothing but the Bement col- 

 lection is now on exhibition in the desk cases of the Mineral 

 Halls, but all the best specimens in the previous Museum col- 

 lection have been retained and have been arranged in syste- 

 matic order in the drawers of the desk cases, awaiting the time 

 when more exhibition space shall be available for minerals.
