 cates a vera causa, the origin, probably, of certain changes upon 

 the earth ; but it is not the ultimate and complete theory of the

 mations in the moon, with a view to their geological relations. In 

 so far as general selenography is concerned, the labours of Beer 

 and Miidler leave nothing to be desired.
