Ordinary Meeting, December 30th, 1863. 
E. W. Binney, F.R.S., F.G.S., President, in the Chair. 
Mr. Samuel Ogden was elected an Ordinary Member of 
the Society. 
Mr. T. T. Wilkinson, F.R.A.S., said that, in a Paper 
“ On the Burnley Coal Field,” prepared by Mr. Joseph 
Whitaker, of Burnley, and himself, and read before the 
Geological Section of the British Association, at Manchester, 
they gave a sketch of the principal mines in this district, but 
they purposely omitted all mention of those whose thickness 
did not exceed one foot. There are, however, one or two of 
these thinner mines which may hereafter become worthy of 
notice, and hence he offered the present note as an addition 
to Mr. Hull’s valuable synopsis in pp. 133-4 of his “ Coal 
Fields of Great Britain.”
