with debris. Sufficient, however, is seen to indicate the direction 
of the dip. A fault appears to have squeezed in an angular bit 
of pebbly conglomerate of Rhetic age, consisting of Limestone, 
black chert, angular stones and water-worn rounded pebbles, on 
which the black clays rested, and reminding me forcibly of the 
same deposit seen near Hapsford Mills, in the Vallis. Only a few 
inches, some 4 or 5, of Black Rhetic Shales cap the mass of 
Limestone at the S.W. end, but these gradually thicken out to 
the N.E. of the section. The total depth of the beds exposed is 
about 14ft. 7in., but what the thickness of the Limestone may be 
beneath its superincumbent deposit is not easy to judge, and, 
from the absence of fossil evidence, a definite conclusion as to its 
position in that series cannot be arrived at—whether, that is, we 
have here an exposure of Upper, Middle or Lower beds—pro- 
bably the first of the three. On a subsequent visit through the 
kindness of Mr. Batey the Limestone had been proved to 
‘continue right to the bottom of the section, and it was stated by 
him that at about l5yds. S. from the present face the solid beds 
had been worked out, and were found resting upon Black Shales. 
Does this fact indicate that these beds belong to the Upper or 
Lower portion of the series—in both of which shaly beds occur ? 
Further opening up, or rather deepening down, of this section 
can alone determine. This further extension and over-lapping of 
those remarkable beds (the Rhetics), whose existence in these 
parts, if not in England, was first made known to the Geological 
world by the late Charles Moore, a former member of this Club, 
seemed to me worthy of record, and to be one of the objects for 
which we have been especially constituted. 
ADDITIONAL NOTES ON THE VOBSTER QUARRY. 
It now remains for me to say a few words explanatory of the 
section which, by the kindness of Mr. Batey, I am enabled to 
bring before you this afternoon. In the section printed in the
