HUGHES : IXGLEBOROUGH. 
We want, also, to get more evidence as to the remains of 
placoid fish found in the lower part of one of these pockets 
under the western precipices of ^loughton. These are found 
in the lowest part of the Carboniferous of Belgium and the 
South-west of England ; and under Moughton occur in the 
geological equivalent of the beds which were being laid down 
in Belgium, while the floor on which Ingleborough has been 
built up was still only the shallow shore of the advancing Devono- 
Carboniferous sea. 
De Koninck and Lohest say with regard to this: — " II 
s'ensuiverait que les nombreuses couches qui existent en Belgique 
entre la zone a Chonetes payilionacea et le Devonien superieur 
seraient en partie representees aux environs d' Ingleborough 
par quelques dizaines de metres de conglomerats, base du 
Mountain Limestone." 
If these few fossils suggest so much we may hope that 
dihgent search may be rewarded with further results. But 
the all-important point is this, that every zone in every separate 
exposure must be separately studied and the fossils of every 
zone in each locality carefully labelled in the field and kept 
apart with proper references to sections and maps.
