Vol. 70.] FOSSIL FLORA OF THE KENT COALFIELD. 



59 



Of the foregoing species the most remarkable is the doubtful 

 record of Pecopteris arborescens (Schloth.), see p. 73, PL XI, 

 figs. 2 & 7, which has hitherto been regarded as confined to the 

 Upper Coal Measures. 



V. The Woodkesbokough Boeing. 

 (Lat. 51° 15' N., long. 1° 17' E.) 



A boring to the south-west of Woodnesborough, not very far 

 from Sandwich, penetrated the entire thickness of the Coal 

 Measures in this district, and ended in the Carboniferous Limestone. 

 The whole of the 1549 feet of measures proved by this boring 

 belong to the Middle Coal Measures. The plant-remains, however, 

 were not particularly abundant, and were often badly preserved, 

 though thirty-two species were determined.
