Note 2 — Chapter IV
Reading edition
It is very remarkable that in the child's bashfulness we find a native nervous response to the presence of persons. And it is curious to note that, besides the general gregariousness which many animals have, they show in many instances special responses of the presence of creatures of their own kind or of other kinds. Dogs seem to recognise dogs by smell. So with cats, which also respond instinctively with strong repulsion to the smell of dogs. Horses seem to be guided by sight. Fowls are notoriously blind to shapes of fowls, but depend on hearing the cries of their kind or their young.
