Castleford to Thorp Salvin." I cannot but congratulate the 
Society that the Council have decided to publish all future 
papers with the same type and paper, and similarly illustrated 
with maps, drawings, sections, and diagrams. It adds not a 
little to the beauty and usefulness of these geological maps, 
that the groups are distinguished by appropriate emblems 
and not by colour. It would be desirable that the distinctive 
emblems adopted in these local maps and sections should be 
retained in all our future publications, and be as fixed in 
denoting geological formations and agricultural soils, as the 
lines in heraldry are to mark colours. 
Before we proceed to the usual business of the meeting, 
I would advert to one point more, — the formation of a 
Museum at Wakefield, of the various specimens and models 
connected with the objects of the Society. Perhaps my 
attention has been more particularly called to this point by 
inspecting (as I have been permitted to do this morning) the 
valuable and interesting collection contained in the rooms 
above. 
A collection of specimens from the coal and iron works 
alone, would form a most instructive school for future in- 
quirers, and contribute greatly to aid and direct the pursuit 
of our geological researches. 
I have a few specimens of septaria, containing organic 
remains, which were dug out in the cuttings of the York and 
North Midland Railway, near my residence, and which (if 
they are worth your acceptance) I shall be most happy to be 
permitted to place in your Museum : as also some curious 
shaped stones similar to those figured in Dr. Buckland's 
Bridgewater treatise, and called by him asaphons : his speci- 
mens came from Elsecar, and perhaps the finding them at 
Castleford may tend to show the identity of the coal beds at 
that place with those of Whitwood and Castleford. 
I will not trespass any longer on your patience, but will
