Moore first directed his attention to the subject. Three well 
drawn plates accompany the descriptive list of the genera and 
species, The original drawings for these plates were done by his 
sister, who was of great assistance to him in his illustrations, and 
whose decease before his own he always deeply regretted. 
One other contribution was made to the Society at their 
Axbridge Meeting in 1868, “On the Geology of the Mendips” ; 
but this appears to have been a short epitome only of a more 
elaborate communication to the Geological Society the preceding 
year, and made more with the object of treating of the physical 
revolutions which had been in progress in the area, than to 
refer at any length to the still more interesting paleontological 
facts thereby involved. At the same time, he incidentally men- 
tions the discovery of a bed of Shale in the Radstock coal field, 
almost entirely composed of the minute seeds of the coniferous 
plant, Hlemingites gracilis ; and accounts for the Mendip upheaval 
by volcanic agency, stating that the presence of this agent he had 
recently discovered in the Basaltic dyke, near Stoke lane. In an 
address on the Banwell bone caves “ delivered before the Society 
(probably the Som. Arch. and Nat. Hist. Soc., though the name is 
not mentioned) at the *Cheddar Field Meeting, 1877,” this view 
again crops up. He there expresses his dissent from the theory 
attributing the formation of caverns in the limestone districts to 
the action of water, thinking that was not a sufficient agent ; and 
states his opinion that the fissures were first formed by volcanic 
action and subsequently enlarged by the influx of vast streams of 
water due to the melting of the ice that covered the neighbouring 
hills in the Glacial period. This view of volcanic agency he clung to 
persistently throughout ; to most geologists however at the pre- 
sent day he seems to have strangely disregarded the more generally 
received opinion that this voleanic outburst was the result not the 
cause of the Mendip disturbance. This was apparently his last 
* If this be correct this was his last attendance at the Society’s 
- Meetings.
