In this respect they seem to which it is susceptible, as heat, light, electricity, and surpass all other animals; not only in reference to magnetism. We know nothing, by experience, of a the rapidity of their movements, but also in constate of perfect rest,—of absolute repose, but, on the tinuing them for a long time without taking food or contrary, wherever we turn our eyes we detect decisive rest. It is well ascertained that land birds cross vast proofs of activity.
