May 9th 73/ When a dog at home sees another dog at some hundred yards distance, he shows by his actions that he knows it is a dog & not a sheep or hare (& yet he will know many individual dogs): if when he comes near he perceives that it is comrade but never instantly others, now he have has an abstract or general idea of a dog & not of any particular dog - so if he sees a hare in the distance & in this case he can know no individual hare.

Polly taught to beg for food will sometimes beg to anyone to be let out of window: here she performs gestures for a very general notice of a desire of some object & supplication to the person to grant it. (the cry of danger is a signal to others)

I might put note – under Reason, referring to the excellent article in opposition to Mivart's article – after quoting Huxley.

So when I say in an eager voice to Polly – "where is it" - she thinks there is something to be hunted & looks to all near bushes & up the trees, as squirrels more interest it - But then takes my tone of voice in abstract sense that there is something to be hunted for. Snow W remarks that the best way is to say that we can perceive no difference in mind of man & animal under certain circumstances, as the easiest all [illeg] He who is prepared to say that self-consciousness whatever may be meant wd not be developed from the other mental powers, as soon as they become highly developed, many partly take the stand on this distinction between man & animals. To me it seems observing when senses become highly developed & the mind very active & the memory rightly stored, many wd reflect on himself & wd become steadily self-conscious.
