f22t CONCLUSION, 



we can alone look for any considerable progress 

 towards perfection. I sliall therefore conclude 

 with the words of Seneca, which, in the present 

 case, are exceedingly applicable: '' Multuni 

 ** restat operis, multumque restabit, nee ulli 

 " nato post mille secula priecludetur occasio 

 " ahquid adhuc adjiclendi,"
