Dear members In a 19th century document about the lease to mine coal in an area of Gloucestershire, England is the statement ".. lease of the Rangeworthy Colliery will expire by [effluxien] of time" The word "effluxien" was not clear so our spelling might be wrong. Please can anyone help with the meaning of "effluxien"? Thanks in anticipation, Mike Whitehead on behalf of the South Gloucestershire Mining Research Group.
