MR. A. J. JUKES-BEO-WNE OK" AN OUTLIER [Aug. 1 898, 



It would appear, therefore, that the full thickness of the calcareous 

 sandstone is from 38 to 40 feet, which, with 2 feet of overlying 

 quartziferous limestone, gives a total of 40 to 42 feet for the Ceno- 

 manian near Wilmington. This is a much greater thickness than 

 it attains anywhere along the coast, the greatest development there 

 being in Hooken Cliff, where it is 24 feet thick. 



The following is a list of the fossils which I was able to obtain, 

 and it will be seen that the fauna is similar to that of the beds on 

 the coast, as recorded in the paper by Mr. W. Hill and myself
