M. Ribot says a little further on: “Originally man had considerable trouble in taming the animals which are now domesticated; and his work would have been in vain had not heredity” (memory) “come to his aid. It may be said that after man has modified a wild animal to his will, there goes on in its progeny a silent conflict between two heredities” (memories), “the one tending to fix the acquired modifications and the other
to preserve the primitive instincts. The latter often get the mastery, and only after several generations is training sure of victory. But we may see that in either case heredity” (memory) “always asserts its rights.”
How marvellously is the above passage elucidated and made to fit in with the results of our recognised experience, by the simple substitution of the word “memory” for heredity.

I cannot refrain from bringing forward a few more instances of what I think must be considered by every reader as hereditary memory. Sydney Smith writes:—
“Sir James Hall hatched some chickens in an oven. Within a few minutes after the shell was broken, a spider was turned loose before this very youthful brood; the destroyer of flies had hardly proceeded more than a few inches, before he was descried by one of these oven-born chickens, and, at one peck of his bill, immediately devoured. This certainly was not imitation. A female goat very near delivery died; Galen cut out the young kid, and placed before it a bundle of hay, a bunch of fruit, and a pan of milk; the young kid smelt to them all very attentively, and then began to lap the milk. This was not imitation. And what is commonly and rightly called instinct, cannot be explained away under the notion of its being imitation.” (Lecture xvii. on Moral Philosophy.)
It cannot, indeed, be explained away under the notion of its being imitation, but I think it may well be so under that of its being memory.
Again, a little further on in the same lecture as that above quoted from, we find:—
“Ants and beavers lay up magazines. Where do they get their knowledge that it will not be so easy to collect food in rainy weather as it is in summer? Men and women know these things, because their grandpapas and grandmammas have told them so. Ants hatched from the egg artificially, or birds hatched in this manner, have all this knowledge by intuition, without the smallest communication with any of their relations. Now observe what the solitary wasp does; she digs several holes in the sand, in each of which she deposits an egg, though she certainly knows not (?) that an animal is deposited in that egg, and still less that this animal must be nourished with other animals. She collects a few green flies, rolls them up neatly in several parcels (like Bologna sausages), and stuffs one parcel into each hole where an egg is deposited. When the wasp worm is hatched, it finds a store of provision ready made; and what is most curious, the quantity allotted to each is exactly sufficient to support it, till it attains the period of wasphood, and can provide for itself. This instinct of the parent wasp is the more remarkable as it does not feed upon flesh itself. Here the little creature has never seen its parent; for by the time it is born, the parent is always eaten by sparrows; and yet, without the slightest education, or previous experience, it does everything that the parent did before it. Now the objectors to the doctrine of instinct may say what they please, but young tailors have no intuitive method of making pantaloons; a new-born mercer cannot measure diaper; nature teaches a cook’s daughter nothing about sippets. All these things require with us seven years’ apprenticeship; but insects are like Molière’s persons of quality—they know everything (as Molière says) without having learnt anything.
