I was so much impressed with these facts that I strongly insisted, in 1839 and 1845, on this "law of the succession of types,"-on "this wonderful relationship in the same continent between the dead and the living."
Aipaturiko egitateek hain eragin handia egin zidatenez gero, 1839 eta 1845ean indarrez mintzatu nintzen behin eta berriz "tipoen hurrenketa lege" honi buruz, "kontinente berean hilen eta bizien artean dagoen ahaidetasun miresgarri" honi buruz.
