270 Notice on Vegetable Fossils. 
by the reasons which lead to its admission in the speciai 
work which my son will publish on this subject. 
I stated, at the commencement of this notice, that the 
fact here described was not new to geologists. Among the 
instances which have been noticed of the stalks of fossil veg- 
etables, traversing several strata, or being placed vertically 
in the bosom of the earth, I shall call to recollection those 
which appear to me to have the strongest analogy with the 
example of the mine of St. Etienne: these citations will 
contribute to establish the resemblances equally real and 
remarkable which the coal grounds of all countries. offer, 
in every particular, as well of their formation as of their 
structure. 
Mr. Mackensie observed in the coal grounds of Scotland, 
near Pennycuik, ten ‘miles from Edinburgh, a vertical 
trunk of the length of about 12 decimeters (4 feet), which 
was composed of carbonaceous sandstone (psammite) and 
the bark or the substance that here replaces it is composed 
of coal. This trunk was not only striated longitudinally 
like the stalks of St. Etienne, but was divided like them by 
transverse sections or articulations.* 
A fact, very similar to the above, appears to have been 
observed in the coal ground of South Shields.+ 
Mr. de Schlotheim also cites instances of vertical stalks at 
Kiffhaiiser, in Hartz,{. in the mines of Maneback, near 
d’Ilmenau, &ce. 
But the instances which have the strongest analogy with 
that which I have described, are those observed in Saxony 
by Werner, by Messrs. Voigt and d’Aubuisson, in the coal 
grounds of the environs of Hainchen, and by Messrs. Habel 
and Noggerath, in the coal mines of the country about Saar- 
bruck. 
* Bibliothique Universelle V. VIII. p. 256. The figure which is there 
given represents this trunk with roots, and as rising above the surface of 
the soil; but it has been found that this was an error in the design, and that 
behind it should have been represented the layers in which it was, and re- 
mained engaged. 
+ Ibid. V. VIII. p. 234." This fact, presented ina very vague manner, 
can hardly be given as an example from which useful consequences can be 
deduced.
