I. Introductory. 



Tn the present paper I give the results of an examination of the 

 fossil floras of the cores of ten further borings in the Coal Measures 

 of the central, northern, and eastern portions of the Kent coal- 

 field, which have been completed during the last seven years. As 

 a rule, plant-remains proved to be abundant in these cores, and they 

 have furnished invaluable evidence as to the geological structure o£ 

 the coalfield. The whole of these new borings penetrated much 

 deeper into the Coal Measures than those initiated at an earlier 

 period in Kent, and thus the evidence of the fossil floras has proved 

 to be much more complete than in the case of the cores already 

 recorded. In several instances the borings proved the entire 

 thickness of the Coal Measures, as developed in those particular 

 areas, and in one locality as much as 2705 feet of measures were 

 proved. 



One boring, Barfreston, where +2103 feet of Coal Measures 

 were proved, lies in the central area, and so does the Tilmanstone 

 sinking, from which a few plants were also obtained. Next, we have 

 a group of six borings in the northern region, including Groodne- 

 stone (with -f 1718 feet of Coal Measures), Woodnesborough
