Note {109} — PART II{104}.

The absence of intermediate forms between living organisms (and also as regards fossils) is discussed in the Origin, Ed. i. pp. 279, 280, vi. p. 413. In the above discussion there is no evidence that the author felt this difficulty so strongly as it is expressed in the Origin, Ed. i. p. 299,—as perhaps “the most obvious and gravest objection that can be urged against my theory.” But in a rough summary written on the back of the penultimate page of the MS. he refers to the geological evidence:—“Evidence, as far as it does go, is favourable, exceedingly incomplete,—greatest difficulty on this theory. I am convinced not insuperable.” Buckland’s remarks are given in the Origin, Ed. i. p. 329, vi. p. 471.
