 by the goniometer and determined. 



They comprise the most important crystals of the species of native Cop])er, Gold, and 

 Sulphnr, of Blende, Argentite, Redruthite and other species with less extensive suites of 

 crystals. Eight s})ccimens of Native Silver, one of a new amalgam, eight of (iold, and 

 nine of other minerals have undergone (generally ([uantitative) analysis in the Laboratory 

 for the purpose of the catalogue. 



Sections for the microscope of 44 rocks have been made in the Department; and the 

 analysis of the minerals composing and the gas occluded in the Melbourne meteoric iron 

 have been concluded. 



The Collection of Meteorites has received the adilition of 13 specimens, 12 of which 

 represent meteoric falls new to the colleclion. They have been for the most part 

 acquired by the method of exchange.
