Forty-second Annual Report on the 



on entering the room, and so continuing from left to right in con- 

 secutive order to and including case No. 26. There are on exhi- 

 bition in the wall cases upwards of 2,400 specimens. They are 

 mounted on wooden tablets with the front edge beveled for the 

 attachment of the label. The labels have the name of the min- 

 eral species and variety printed in two lines at the top, and below 

 these are written the locality, and the name of the donor or col- 

 lection from which the specimens is taken. The first table case, 

 near the entrance door, is occupied by pseudomorphs and an incom- 

 plete collection of minerals illustrative of their physical properties ; 

 and, for the present, by four large Toluca meteorites. The second 

 table case, in the front room, has in it the better examples 

 of crystallized minerals belonging to the Museum, anfl also some 

 of the more beautiful specimens without reference to crystalliza- 

 tion. There are in this case about 1,100 specimen s. 



In the long table case in the back room the showy minerals 

 from Bergen Hill, N. J., are exhibited, .numbering about 300 

 specimens. They represent nearly all the species ever found in 

 that district, and the collection is probably the best of its kind in 

 the country. It possesses especia] value as representing a group 

 of minerals occurring in a particular district. The pectolites, 

 natrolites and apophyllites are remarkably fine. 



The case of precious stones, also in this room, has in it fine 

 specimens, mostly of the varieties which are employed for gems. 

 A catalogue of the case was given in the last annual report. 

 During the year the following cut stones have been added, viz.: 

 Amethyst from South Carolina, Jadite from China, Green Garnet 

 from Siberia. 



The additions to the mineralogical collection are not numerous, 

 but they are of particular interest. Especially deserving of notice 

 here is the collection of New York island minerals, purchased of 

 Geo. F. Kunz, of Hoboken, N. J. It contains all the characteristic, 

 as well as common, mineral species found occurring naturally on 

 the island, and, in view of the early disappearance of the out- 

 cropping ledges and the covering of mineral localities by the 

 growing city, its value must increase. Three masses of meteoric 

 iron from Toluca Valley, Mexico, weighing eighteen, fifteen 

 and three pounds, respectively, also deserve mention, as they serve 

 as representatives of this class of meteorites. By the side of 

 them lies a beautiful model of the Cabin Creek, Arkansas, meteoric
