TEREACES AND EIVER VALLEYS OP WESTERN EUROPE. 297 



NOTE. 



A valued member, Mr. H. P. Malet, contests the idea of the 

 upheaval of the earth's surface, and quotes, as expressing his 

 views, Dr. J. W. Gregory's statement that *' the plan of the 

 earth may be attributed to the continual foundering of the earth's 

 extex'nal shell owing to the unceasing shrinkages of its internal 

 mass." Yet, as Professor Hull points out, in I'eply, no one has 

 expounded more clearly than Sir C. Lyell, that the contraction 

 of the crust — due to internal " shrinkage " — necessarily gives 

 rise to upheaval of the crust at various places. Perhaps Mr. 

 Malet will permit some remarks on this subject, kindly contri- 

 buted by him, to be considered in the coming session. — Ed.
