ies of the mind{88}, but merely with their differences in each of
the great divisions of nature. Disposition, courage, pertinacity <?>,
suspicion, restlessness, ill-temper, sagacity and <the> reverse
unquestionably vary in animals and are inherited (Cuba wildness dogs,
rabbits, fear against particular object as man Galapagos{89}). Habits
purely corporeal, breeding season &c., time of going to rest &c., vary
and are hereditary, like the analogous habits of plants which vary and
are inherited. Habits of body, as manner of movement d^o. and d^o.
Habits, as pointing and setting on certain occasions d^o. Taste for
hunting certain objects and manner of doing so,--sheep-dog. These are
shown clearly by crossing and their analogy with true instinct thus
shown,--retriever. Do not know objects for which they do it. Lord
Brougham's definition{90}. Origin partly habit, but the amount
necessarily unknown, partly selection. Young pointers pointing stones
and sheep--tumbling pigeons--sheep{91} going back to place where born.
Instinct aided by reason, as in the taylor-bird{92}. Taught by parents,
cows choosing food, birds singing. Instincts vary in wild state (birds
get wilder) often lost{93}; more perfect,--nest without roof. These
facts [only clear way] show how incomprehensibly brain has power of
transmitting intellectual operations.

{88} The same proviso occurs in the _Origin_, Ed. i. p. 207, vi. p.
319.

{89} The tameness of the birds in the Galapagos is described in the
_Journal of Researches_ (1860), p. 398. Dogs and rabbits are
probably mentioned as cases in which the hereditary fear of man has
been lost. In the 1844 MS. the author states that the Cuban feral
dog shows great natural wildness, even when caught quite young.

{90} In the _Origin_, Ed. i. p. 207, vi. p. 319, he refuses to
define instinct. For Lord Brougham's definition see his
_Dissertations on Subjects of Science etc._, 1839, p. 27.

Sketches_, p. 403.

{92} This refers to the tailor-bird making use of manufactured
thread supplied to it, instead of thread twisted by itself.

{93} _Often lost_ applies to _instinct_: _birds get wilder_ is
printed in a parenthesis because it was apparently added as an
after-thought. _Nest without roof_ refers to the water-ousel
omitting to vault its nest when building in a
