Origin of Species Variorum

Comparison with 1866

&c., have unanimously, often vehemently, maintained the immutability of species. But it is evident from the recent works of Sir Charles Lyell, that he now almost gives up this view; and some other great geologists and palæontologists are much shaken in their confidence. I feel how rash it is to differ from these great authorities, to whom, with others, we owe all our knowledge. Those who think the natural geological record in any degree perfect, and who do not attach much weight to the facts and arguments of other kinds given in this volume, will undoubtedly at once reject my theory. For my part, following out Lyell's metaphor, I look at the natural geological record, as a history of the world imperfectly kept, and written in a changing dialect; of this history we possess the last volume alone, relating only to two or three countries. Of this volume, only here and there a short chapter has been preserved; and of each page, only here and there a few lines. Each word of the slowly-changing language being more or less different in the interrupted succession of chapters, may represent the apparently abruptly changed forms of life, entombed in our consecutive, but widely separated formations, which falsely appear to have been abruptly transformed. On this view, the difficulties above discussed are greatly diminished, or even disappear.
