HUTTONIAN THEORY. 





I cannot pretend to remove entirely the dif- 

 culty which is here ftated ; yet I think the 

 following remarks may go fome length in doing 



fo. 



324. It is certain, that from the prefent ftate 

 of the lake of Geneva, and of the ground 

 round it, we can hardly draw 



any 



feren 



as to its orig 

 traced, with h 



dimenlio 

 fual fkill. 



SaufTu 



h 



th 



rks of th 



courfe of the Rhone, on a level greatly above 

 the prefent ; and, by obfervations on the lide of 

 Mount Saleve, has found proofs of the running 



r 



of water, at lead 200 toifes above the prefent 

 fuperficies of the lake. But, if ever the fuper- 



ficies of the lake Hood at this height, or at this 

 height nearly, though we can conjedure but 

 little concerning the flate of the adjacent coun- 

 try, which no doubt was alfo on a higher level, 

 the lake may very well be fuppofed to have been 



•lit doH'fl SUP'; of far greater dimenlions than it is now. 



It may 



. fjjjj niome"^''' have occupied the whole fpace from Jura to Sa- 



leve, and included the Lake of Neufchatel ; fo 

 that it may have been of magnitude fafficient 

 to receive the fpoils of the Valiais, which, as the 

 furface of its waters lowered, may have been 

 wailied away and carried down to the fea. Thus 

 it may have afforded a temporra-y receptacle for 

 the debris of the Alps, and may have ferved for 

 an entrepot, as it were, where thofe debris were 



depolited.
