specimens, a very complete metallurgical rather than mineralogi- 

 cal exhibit of the gold, silver, copper, zinc, and lead from Chili. 

 Among the few specimens of mineralogical interest were two 

 beautiful groups of proustite (ruby-silver) from Caracoles, and 

 a fine display of nitrate of soda from Tarapaca. 



The Paraguayan Rei)ublic showed little else than some hand- 

 some marbles and specimens of rock and refined salt. 



Among the forty-four exhibits from Salvador may be men- 

 tioned native platinum, iron pyrites, jasper, and porphyry. 



In the New Zealand Court were two large polished blocks of

 magnificent specimens of scheelite. 



In the South African Pavilion were exhibited from the new 

 gold-fields of South Africa, in a large safe, native gold valued at 

 over $60,000. 



In the Esplanade des Invalides, in the Palace Algerien, was 

 an interesting collection of minerals from the province of Con-

 aragonite), concretions of phosphorite and calamine, and groups 

 of senarmontite crystals. 



The Madagascar Pavilion contained a series of gravels con-

After the reading of the above-mentioned papers, Dii. Hunt 

 exhibited a large series of specimens of great interest, illustrat-

 antimony from California, a so-called amber from Mexico, and
