visited the quarry again, and further facts of the utmost 
importance had been brought to light under Mr. Batey’s 
superintendence. The face of the quarry had been worked back 
at the spot where we had during the October visit found the 
infillings of Millstone Grit, and had exposed a good section of 
that rock resting on clays, and these latter on the Mountain 
Limestone giving the following section:—Clay and Millstone 
Grit debris, 6 feet ; solid beds of Millstone Grit, 10 feet ; shales 
of various colours, reddish and dark blue, 8 feet; total depth to 
top of Mountain Limestone, 24 feet. In this section the beds 
dipped steeply to the north, and were in their natural position. 
Some few yards to the east of this were several small step faults, 
and then a tumbled mass of clay and rock, beneath which a tunnel 
was being driven about 60 feet below the surface running directly 
north and reaching inwards to a depth of 20 feet. The men 
were then in the act, during our visit, of attacking a hard mass of 
rock which gave a ring seemingly not that of Limestone, and on 
close examination it proved that they had driven through the 
softer beds of blackish-blue, and reddish shale before alluded to, 
as resting on the Limestone to the westwards, and had just come 
upon the hard beds of Millstone Grit ; these were dipping sharply 
to the south or south-west, about 45° to 50° in a direction beneath 
the superincumbent Limestone outside the tunnel to the eastwards. 
Thus these beds had been turned-topsy turvy without any doubt, and 
the Millstone Grit was found in situ between the Mountain Lime- 
stone and the Coal Measures, and so Mr. Woodward’s chief 
objection to the overthrow theory, i.e. the absence hitherto of 
any trace of Millstone Grit in this position, appears to me to have 
been met. 
May I further state that not an isolated fact only, but two 
or three facts in connection with the Vobster Inversion have 
been brought before your notice, and if they have, in con- 
junction with the other facts made known from time to time 
by Mr. McMurtrie, in any way served to throw additional light
