ing found in a vertical position are very frequent. In those 
cited by Mr. Noggerath and by ourselves, there was not 
merely a single trunk, of a large tree, but there were ma~ 
ny trunks ; and in the mine of Treuil, which forms the prin- 
cipal object of the present notice, it is, as it were, a forest of 
slender stalks which remain parallel to each other. Be- 
sides, the nature of the soil to which the vegetables would 
adhere by their roots should be different, or at least, very 
distinct from that of the rocks which enclose them. It is 
perhaps more difficult to imagine that these sandy rocks 
should envelope them after their transposition, without de- 
ranging them, than thatit should have been deposited among 
them in the place where they grew, and where they were 
solidly fixed in the earth. And if we even suppose that 
these vegetables may have been transplanted thither, without 
losing their vertical positition, we cannot admit that they 
were brought from a great distance ; and the insurmounta- 
ble objection against the hypothesis which would bring these 
vegetables from the tropical regions into our climate, would 
still exist. 
Nevertheless the facts cited by Mr. Carpentier, and his 
observations thereon, tend to throw a degree of uncertain- 
ty over the primitive situation of those vertical stalks, which 
ought to engage us to continue our observations and our re- 
searches, and teach us that we cannot yet draw from these 
facts any absolute and general conclusion.

Crystalized Steatite. 
This rare mineral was found by Dr. E. Emmons in Mid- 
dtefield, county of Hampshire. The crystals usually occur 
in groups on masses of Steatite. On a piece three inches 
long and two broad are more than forty crystals, most of 
which are pyramids projecting from the mass, but a few are 
horizontal. Though most of the crystals are small, some
