[{448}] Origin, Ed. i. p. 423, vi. p. 579.
[{449}] The discussion here following corresponds more or less to the Origin, Ed. i. pp. 411, 412, vi. pp. 566, 567; although the doctrine of divergence is not mentioned in this Essay (as it is in the Origin) yet the present section seems to me a distinct approximation to it.
[{450}] The author probably intended to write “groups separated by chasms.”
[{451}] A similar discussion occurs in the Origin, Ed. i. p. 427, vi. p. 582.

[{453}] Origin, Ed. i. p. 430, vi. p. 591.
[{454}] Origin, Ed. i. p. 434, vi. p. 595. Ch. VIII corresponds to a section of Ch. XIII in the Origin, Ed. i.
[{455}] Origin, Ed. i. p. 434, vi. p. 596. In the Origin, Ed. i. these examples occur under the heading Morphology; the author does not there draw much distinction between this heading and that of Unity of Type.
[{456}] See Origin, Ed. i. p. 436, vi. p. 599, where the parts of the flower, the jaws and palpi of Crustaceans and the vertebrate skull are given as examples.
[{457}] The author here brings Unity of Type and Morphology together.
