    circumstance of which I shall consider the reason very fully when I come to describe the nervous system of some of the insects in whom it is even more decided, though the general arrangement is equally simple. The structure of the nervous cord of the lobster is particularly interesting to us as affording a very perfect type of the spinal cord in man, in as much as distinct columns for motion and sensation are capable of easy demon- stration after the parts have been immersed for some time in alcohol; an arrangement which, though not susceptible of proof in the Asterias, in all probability exists as perfect as in the specimen before us. For, as Mr. Newport, in the interest- ing papers which he laid before the Royal Society, very justly observes, the same train of reason- ing which led Sir Charles Bell to his discoveries in the nervous system of the higher animals, must long ago have taught us, that since the laws of na- ture are simple and uniform, the same principle exists through the whole series of animated be- ings ;—that however altered in arrangement or appearance in different parts of the series, struc- tures corresponding to those which are endowed with especial properties in man and his immediate affinities, exist in every organized creature havino- the powers of locomotion and sensation. In the month of August, 1833, says Mr. New- port, after many dissections and examinations of the animal [the lobster] in its recent state, I
