The second brancli of our enquiry, respecting changes of 

 the organic world, relates to the processes by which the

 the effects of geological causes into two great classes : those 

 produced during the submersion of land beneath the waters, 

 and those which take place after its emersion. Agreeably to 

 this classification, I shall consider, first, in what manner
