THE COLLECTION OF MINERALS 
specimens of diopside, the silicate of copper, in well-formed hexagonal 
crystals; very attractive suites of wernerite, vesuvianite and zircon in 
single individuals and groups of tetragonal crystals, and crystallized 
topaz in a diversity of crystal forms and a variety of color as pleasing 
to the eye as they are interesting.
