In the corresponding passage in the Origin, Ed. i. p. 430, vi. p. 591, the term general is used in place of generic, and seems a better expression. In the margin the author gives Waterhouse as his authority.

In a corresponding passage in the Origin, Ed. i. p. 423, vi. p. 579, the author makes use of his knowledge of pigeons. The pseudo-genera among dogs are discussed in Var. under Dom., Ed. ii. vol. I. p. 38.

A general statement of the influence of conditions on variation occurs in the Origin, Ed. i. pp. 131-3, vi. pp. 164-5.

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.

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.
458
The solid-hoofed pigs mentioned in Var. under Dom., Ed. ii. vol. II. p. 424 are not Lincolnshire pigs. For other cases see Bateson, Materials for the Study of Variation, 1894, pp. 387-90.
459
In the margin C. Bell is given as authority, apparently for the statement about Plesiosaurus. See Origin, Ed. i. p. 436, vi. p. 598, where the author speaks of the “general pattern” being obscured in “extinct gigantic sea lizards.” In the same place the suctorial Entomostraca are added as examples of the difficulty of recognising the type.

The uselessness of the branchial arches in mammalia is insisted on in the Origin, Ed. i. p. 440, vi. p. 606. Also the uselessness of the spots on the young blackbird and the stripes of the lion-whelp, cases which do not occur in the present Essay.
463
In the Origin, Ed. i. pp. 442, 448, vi. pp. 608, 614 it is pointed out that in some cases the young form resembles the adult, e. g. in spiders; again, that in the Aphis there is no “worm-like stage” of development.
464
In the Origin, Ed. i. p. 449, vi. p. 618, the author speaks doubtfully about the recapitulation theory.
