 plants were also sent home, of the existence of which there are no traces. The live 

 plants brought home by the squadron amounted to 254 species, and these now form 

 part of the greenhouse collection.

The inadequacy of the space in the Hall of the Patent Office at present allotted for 

 the departments of geology and mineralogy, becomes daily more obvious, as the 

 extent of our collections is better known. The spacious hall is a noble one for the 

 purpose to which it is devoted; but so many distinct sciences claim a share of the 

 room, that onl)^ a small area can be .set apart for any one of them. The collections 

 of the Exploring Expedition .swell out beyond our expectations, and when fully 

 arranged there will be room for little else. 



The packages of mineral and geological .specimens already opened occupy three of 

 the cases in the Hall, and there are yet seven or eight boxes uiitouched. These 

 Expedition collections include suites of .specimens from the following countries 

 and i.slands; 



1. Brazil, illustrating especially the deposits of gold and gems in the great mining 

 di.strict of Minas Geraes; also the structure of the comitry about Rio Janeiro. 



2. Rio Negro, Patagonia, where the extensive pampas of La Plata, and the Ter- 

 tiary deposits upon which they rest, afforded us a series of interesting specimens, 

 exhibiting the character of these great prairies of the south, and the salt lakes that 

 abound over them. 



3. Orange Bay, Terra del I'uego, where terminates the great chain of the .'\ndcs. 

 A .species of fossil and the nature of the rock deposits, appear to afford sufficient 

 evidence of the similar and consentaneous origin of this portion of the chain with 

 the Andes of Chile and Peru. 



4. Chile and the Chilean Andes. The mountains were twice ascended by parties 

 from the Expedition, and specimens obtained, in addition to the rocks of the coast, 

 and ores from copper mines. 



5. Lima and the Peruvian Andes, affording us gold and .silver ores. The summit 

 of the Andes was passed by a party of officers, and among their collections is a 

 fossil Ammonite, a large extinct .species of shell, obtained at a height of i6,cxx) feet.
