which, it is quite clear, must be corrected so far as relates to this 
point. 
4, It must not be understood from the remarks I have made that 
I dispute the existence of an anticlinal axis running nearly east and 
west across the Kingswood Coal-field. I am quite aware that on 
the north of my section, in the Parish of Stapleton, there is a clear 
and well-defined anticlinal axis extending from Bristol, on the West, 
to Wick Rocks, on the East, and which, in fact, gives the geographical 
as well as the geological character to Kingswood Hill: but even on 
the apex of this anticlinal there is no appearance of the Grit ; nor is 
it anywhere brought within at least 400 or 500 yards of the surface. 
One of the main seams of the district—namely, the ‘Great Vein,’ 
marked No. 32 in the annexed list, and shown in my section—has 
been worked over the whole of Kingswood Hill, at the top of the 
anticlinal axis, at a depth varying from 380 to 60 fathoms, and 
from thence northward (at Soundwell) to a depth of 200 fathoms, 
and southwards (at St. George’s) to a similar depth ; but between 
this seam (which is, no doubt, identical with the Bedminster ‘ Great 
Vein’) and the Millstone-grit, there is proved, at Ashton Vale, to be 
an interval of over 300 fathoms; so that it is quite evident that 
the Millstone-grit cannot exist at the surface at Kingswood Hill. 
Conclusion.—The band of sandstone called ‘Holmes Rock,’ 
belonging to the Lower Coal-measures, and shown on the accom- 
panying section, is what has been hitherto mistaken for the Mill- 
stone-grit. The section also shows twenty-one known seams of 
coal, varying from one to four and a half feet in thickness, lying in 
regular order below it. : 
Commercially, then, as well as scientifically, the question as to the 
presence or absence of the Millstone-grit at Kingswood Hill is 
highly important ; for, instead of the bottom of the Coal-measures, 
which the Grit itself would mark, we have a considerable extent of 
valuable Coal-field open to us, which was thought to be barren for 
the future energy, skill, and enterprise of those to whose talent and 
perseverance this country is so largely indebted for its past growth 
and its present prosperity.

gee Cretaceous strata of the South-east and other parts of 
France have for some time specially engaged the attention of 
Geologists; and their differences in petrographic and _palzeonto- 
logical characters have been a continual source of controversy.
