Before bringing this notice to a conclusion, I ought not to omit mentioning 

 the occurrence of some interesting vegetable remains which have been found in 

 the Limestone which I described as forming a stratum to the south of the vale of 

 the Ouse. In connection with large specimens of Lignite, are beautiful Ferns and 

 coniferous plants. There are many cones in excellent preservation, imbedded in 

 the limestone, all of which are about the size of a Brazil nut. The limestone is 

 very similar in its character to that of the Forest Marble. It contains but a small 

 number of shells, among which are the genera, Terebratula, Mytilus, &c. 



It is unfortunate for geological inquiry, that the sections to which reference 

 has been made, and others of a similar kind, are so soon hidden from observation. 

 It has, of course, been an object with me to obtain as many specimens as possible 

 of the fossils and of the beds in which they occur ; and by these I shall be able 

 at any time to confirm the statements I have made. In conclusion, I may be 

 allowed to say that I shall sincerely rejoice if these brief observations may stimu- 

 late the inquiry and elicit the opinion of those who are far more competent judges 

 of the subject than I can pretend to be.*

* The above interesting communication was forwarded to us a few months since ; and 

 we sincerely hope that its publication may induce some competent geologist to undertake 

 an examination of the singular deposit which Mr. Bull has described. Mr. W. H. In- 

 wood, the architect, a zealous collector of fossils, has visited the localities alluded to by 

 Mr. Bull, and we have had an opportunity of examining, at his residence in Euston 

 Square, the specimens obtained by him at the railroad. We were particularly struck with 

 the great variety and beautiful preservation of the Ammonites. The fossil cones are par- 

 ticularly interesting, and occur in a limestone apparently belonging to some member of 

 the oolitic group. — Ed.
