From these considerations, from our ignorance of the geology of other countries beyond the confines of Europe and the United States, and from the revolution in our palaeontological knowledge effected by the discoveries of the last dozen years, it seems to me to be about as rash to dogmatize on the succession of organic forms throughout the world, as it would be for a naturalist to land for five minutes on a barren point in Australia, and then to discuss the number and range of its productions.
Kontsidero guztiongatik, Europa eta Estatu Batuetako mugaldez handiko herrialdeetako geologiaz dugun ezjakintzagatik eta azken urteetako aurkikunndeek gure paleontologi ezagueretan eragin duten iraultzagatik, uste dut forma organikoen hurrenketari buruz dogmatizatzea ausarkeria handia dela, naturalista bat, Australiako toki idorren baten lehorreratu eta bost minutura hango ekoizkinen kopuru eta heda-eremuari buruz eztabaidatzen hastea adinakoa ia-ia.
