94 Mr.. Weaver's Geological Remarks. [Aue. 
.two formations might easily be mistaken for each other, when not 
duly observing their respective boundaries ; and the inference 
then be drawn that the new conglomerate is also associated with 
porphyry and trap. Now in adverting to the Forest of Thurin- 
gia, itis stated, (‘‘ Outlines,” p. 316,) “here we may observe, at 
top a shell limestone, answering to our lias ; then red marle and 
gypsum; the calcareous beds associated with the cupriferous 
‘marl slate; and at buttom the rothe todte.” (See also p. 313.) 
But this so-called rothe todte at. the bottom of the cupriferous 
marl slate, is assuredly the weisshiegende of Freiesleben; that is, 
the new conglomerate, beneath which is to be found the true 
rothe todtliegende in association with trap and porphyry. 
Here then we have a formation which, as the first member of 
anew series, covering the carboniferous series, and extending 
beyond it to the transition series, and even to the primary, distin- 
guished by gypsum as. its occasional companion, beside other 
characters (which I have detailed in the Annals of Philosophy, 
Nov. 1821, p. 255—257), leave no room to doubt its identity 
with the new red conglomerate of England. 
Again, with respect to the supposed alliance of the new con- 
glomerate with porphyry and trap, | confess I do not know an 
instance of the kindin Germany ; and Freieslebenis perfectly silent 
upon any such occurrence. Ofits existence in England, only one 
example is given, and that is admitted to be of a problematical 
character. I have suggested that the amygdaloidal trap in the 
neighbourhood of Exeter might possibly be connected with the 
transition tract of that country: this seems to be denied... Yet, 
as presenting some ground. for the suggestion, | must remark 
that the very able and luminous view of Cornwall, Devon, and 
Somerset, taken by Prof. Sedgwick, inthe first volume of the Cam- 
bridge Phil. Trans., has clearly shown that red transition conglo- 
merate and sandstone occur at least in Somersetshire ; to which 
1 may add that transition red sandstone is of common occurrence 
an Gloucestershire and Herefordshire, being in the former county 
an direct association with amygdaloidal trap, which has sometimes 
salso a porphyritic aspect, including acicular crystals of glassy fel- 
spar. If, however, the conglomerate and sandstone in question 
be not transition, 1 then venture to inquire whether it may not 
be the first floetz or old red sandstone ? Of the existence of the 
Jatter in Somerset, 1 was assured three. years since by the 
researches of my friend, the Rev. Dr. Cooke, who found it sup- 
‘porting the carboniferous limestone of Cannington Park ;,a view 
now apparently confirmed. by the high authority of Mr. Cony- 
-beare. In support of either suggestion, it may also be stated that 
Mo writer appears to have observed any gypsum in the,sandstone 
said to be associated with the trap, while it is not uncommon in 
the extensive tracts of the new red sandstone of that part of the 
kingdom, e.g. in Devon, at Budleigh Salterton near Teignmouth, 
at Sidmouth, and on Blackdown, and again more N. in Somerset
