It is alsonot at all improbable that like beds will be found in other areas wherethe Cincinnati limestones exist. It is of interest to note the fact that,except for some rather unimportant deposits mined some years since inWales, these are the first beds of commercial importance to be foundin the Lower Silurian rocks, despite the fact that as long ago as1888* Prof. N.
