190 Correspondence — Bernard Hohson. 



0. lunata. (The single specimen of 0. lunata recorded from the 

 lower beds in 1906 was found in a detached piece of chalk lying 

 on a ledge about 5 feet up, which I then felt bound to assume 

 against my own views to have been detached from the chalk against 

 which it actually lay, but it is now obvious that it must have 

 slipped down from above.) 



I have also discovered that 4 inches above the highest flint band 

 figured on the southern part there is a sudden but apparently 

 conformable change from white chalk with 0. lunata to grey chalk 

 without 0. lunata. Of this grey chalk a maximum of 18 inches 

 is preserved, containing one definite line of very curious flints. It 

 is a reasonable supposition that this grey chalk is the lowest part 

 of that grey chalk which is the lowest member of the other main 

 series, and that it supplies the hitherto missing link between the 

 two series.

THE DISCUSSIONS AT THE GEOLOGICAL SOCIETY. 



SiE, — I write to strongly express the hope that the suggestion of 

 Dr. Charles Davison, in the February Gteological Magazine, that the 

 reports of discussions of papers read before the Geological Society 

 should be printed exclusively in the Proceedings will not be adopted. 

 Personally I find it very difficult to keep track of and insure the 

 complete collection and preservation of the Proceedings, which I regard 

 as of an ephemeral character and do not consider worth binding. If 

 the discussions are omitted from the Quarterly Journal the report will 

 be incomplete, and many valuable suggestions may be either lost 

 entirely or only preserved by those paragons of method who bind the 

 Proceedings. I would suggest that those who take part in the 

 discussion should be requested, when proofs of the report of their 

 remarks are submitted to them, to eliminate from them everything 

 except what they believe, on mature reflection, to be of value, and 

 that as far as possible the official reporters of the Society should act 

 on the same principle. Then the discussion may be printed in the 

 Quarterly Journal. I think a paper which when printed iti extenso is 

 materially damaged by the report of the discussion cannot be worth 

 much. I have so great a respect for the views of Dr. Davison on 

 most subjects that I regret to differ from him in this case.
