false-seeing anger. 
An illusion just as great, leading to action equally 
violent, but ludicrous rather than painful to witness, 
may be seen in dogs, when encouraged by a man to 
the attack, and made by his cries and gestures to ex-

is precisely the animals, high or low in the organic 
scale, that are social, and possess the instinct of 
helping each other, that will on oceasions attack a
