Specimens in Geology are wanted for a public institution. 
Those of organic remains and of the junctions of rocks are most 
desired. They must be excellent in their kind, of considerable 
size, say from 4 to 8 inches square, fresh, and not rubbed, soiled 
or bruised, extremely well characterized and labelled with care, 
particularly as to locality and geological association. None must 
be sent without previous notice. For such specimens a reasona- 
ble, but not an extravagant, price will be paid. Superior speci- 
mens in mineralogy are included. Letters may be addressed to 
Prof. Silliman at New Hpvet,
