GoLp his antimonial mineral occurs on stibnite, consti- 
ating gang from a thin coating to a quarter of an inch in thick- 
ness, and sometimes crystallized in cavities. The crystals were 
orthorhombic, and are rhombic A rte ss 110° 8’, with the vertical 
edges truncated. It is o when amorphous, but subtranslu- 
cent when crystallized ; the pa resinous, of a faint yellow color, 
with the streak dull yellow to straw-yellow. Hardness=4. G.=

Mr. Goldsmith concludes that the trautwinite is a result of the 
alteration of chromite; and that the silica and lime found in this 
chromite is in the state of trautwinite. The mineral is not acted

e Gardener’s Chronicle — attention to Dr. Regel’s bring- 
ing forward as an “ objection to the Darwinian theory, the cir- 
cumstance that the cultivation on the American vines has resulted, 
in the course of a few score of years, in the production of as great 
an amount of variation as has been obtained in Enrope and Asia 
during tens of centuries.” Upon which it may be remarked, 1, 
that there are in North America several species to work with, 
against the single one cultivated in Europe and western Asia ; 
and, 2, that the American se in question for the most part 
have not been made, but aged selected and improved within the 
So that nature had long ago begun the work which the cultivator 
in this case only accelerates, and directs, and gets the sian for.
