196 THE AGE OP THE LAST UPRISE OF THE BRITISH ISLES. 



The Secretary. — b.c. or a.d. That is quite impossible, and it 

 does not follow. It is not like the case of the introduction of 

 different kinds of architecture in our ecclesiastical buildings in 

 England or Europe which is most remarkable and seems to have taken 

 place over very wide areas. We know when we pass from the Early 

 English to the Decorative, and from the Decorative to the Perpen- 

 dicular styles. We know within a few years when those buildings 

 were erected ;, but we cannot use an argument of that kind with 

 regard to the Stone Age and the Iron Age. 



Professor Orchard. — I thought not. Thank you. 



The Secretary. — They were not contemporaneous all over the 

 earth and in the British Islands. As to the cause, the whole crust 

 of the globe, if we could see it, is qo doubt in motion, but it may be 

 very slow in some parts and comparatively rapid in others. 



I thank you for the kind manner in which you have received my 

 paper. 



The Meeting then terminated.
