3601. As soon as an animal contemplates a part of its body, of its world, and hath consciousness in a general sense, it has also memory. For memory is a repetition of its own condition, not the reiterated feeling of a foreign object.
The Acephalous or anencephalic animals have therefore no memory, because they live only in opposition to the world, but never in antagonism to themselves. Every perception is therefore a new one for them, because it is always an actual object which excites them. Whether Insects have memory, has not yet been made out.
3602. The brainless animals have no ideas, and naturally so, because they have no consciousness.
It would appear likewise that they do not feel pain.
The Cephalozoa have ideas, and quite certainly pains, because they become partly an object unto themselves.

With this memory, however, all the spiritual functions, exhibited by the preceding classes, but chiefly mesmerism, have been bestowed.
3604. Fishes are again provident, zealous animals, that, drawn together by mysterious bands, make the longest voyages, wherein they ascend and descend rivers, knowing how to find their prey over miles in extent.
All the mechanical instincts are, on the contrary, obliterated in them, as being fingerless, finned animals. Their principal business is propagation—Pelvic animals.
