THE AGE OF THE LAST UPRISE OF THE BRITISH ISLES. 191 



The Author explained. — The rise und fall of the spring tides at 

 Liverpool is 26 feet, of which the mean level is 13 feet. This is the 

 "ordnance datum"; add to this 30 feet for the upper level of the 

 terrace and the result is 43 feet, not much below the 50 feet contour 

 and sufficiently near for the purpose in view. 



Mr. Martin Rouse. — Then is not there a slight mistake in the 

 paper 1 Referring to Norway, you say in the paper at pages 183 and 

 184, "When the armies of Rome brought the civilisation of the 

 south into contact with that of the north they found the value of 

 iron already known to their enemies," and it goes on to speak of 

 Roman coins being found along with a boat well made, as proving 

 the Roman occupation of Norway, or as pointing to the Roman 

 occupation. Is not that a slight slip, inasmuch as the Romans never 

 did occupy Norway 1 



The Secretary. — Are you sure of that 1 



Mr. Martin Rouse. — Perfectly, sir. 



The Secretary. — How do you account for the coins being 

 found ? 



Mr. Martin Rouse. — I think they came by trade. The Romans, 

 I assume, occupied a good piece of Germany and they were dri^-en 

 back. 



The Secretary. — They never went across the Baltic, you mean ? 

 Mr. Martin- Rouse. — No. There is no proof that they went 

 across the Baltic. 



The Secretary. — Very well, I thank you. 



Professor Logan Lobley. — As you have been good enough, 

 Mr. Chairman, to ask me to speak on this paper, I have great 

 pleasure in rising to say a few words, as I am greatly interested in 

 it as a geologist and greatly interested in it as a lover of archaeology 

 and a lover of the history of my country. 



Very seldom do we hear a geological paper read which has 

 reference to such modern times as that given by Professor Hull to- 

 day. This brings us quite into an historical period, the second, or 

 third century of our era, and that is quite unusual in geological 

 papers. 



It seems to me from the evidence brought forward in this paper, 

 that the case, as Mr. Martin Rouse has said, has been very well 

 proved, especially by the fact of the Roman wall not having ex- 

 tended quite to the present margin ; that seems very strong evidence
