XII. The Oxkey Boring. 

 (Lat. 51° 10' K, long. 1° 21' E.) 



A boring, near Oxney Court, proved 2705 feet of Coal Measures, 

 and then passed into the Carboniferous Limestone. The higher 

 portion of the measures (about 778 feet, but the exact amount is 

 uncertain) probably ought to be referred to the Transition Coal 

 Measures, on the evidence of the fossil plants. The Middle Coal 

 Measures are estimated at 1927 feet in thickness. The floras of 

 both horizons are representative, nineteen species having been 

 determined from the Transition, and forty-four species from the 

 Middle Coal Measures.
