TN this number will be found a continuation 

 (ante p. 160) of the sections met with in the 

 successful boring after coal at Dover. Complete 

 particulars will be now in the hands of our 

 readers of the whole of the strata passed through 

 to a depth of 2,22iJ feet, where the four-foot seam 

 of coal came to an end, the reaching of which

 characterized fragments of fronds, and the latter 

 by large detached pinnules. M. Zeiller reported 

 as to these, that " in France they abound in the 

 upper zone of the Valenciennes basin, and they 

 have not been met with below, except quite at the 

 summit of the middle zone, and then at one or

caused Mr. Brady to send his triumphant 

 telegram to Sir E. W. Watkin, " Have found 

 four feet seam of good bituminous coal at 2,222 

 feet from surface." 



We have already viewed the various plant-prints 

 which have been met with, and now illustrate 

 the two fossils on which the relative position 

 of the beds to the whole of the Coal Measures 

 is based, namely, Neuropteris rarinervis and N. 



two points only." These fossils are common in 

 the Radstock and Farringdon Beds, which appear 

 to be " a little more elevated than the grasses and 

 flenues beds of the Pas de Calais," from which it 

 is considered that there may still be a great 

 thickness of further coal-bearing beds below the 

 coal of Dover. 



Interesting facts which may bear upon the 

 question of the westerly extension of the Dover
