At this period the embryo is partially organized, having faint traces of segments, and is still enveloped in its embryonal membranes and retains its connection with the shell. In an analogous manner the deciduous, pluteus-condition of the young Echinoderm perishes and is absorbed by the growing body of the permanent adult stage.
Some new stimulation may thus ecphorate an old engram. Now the entire embryonal development of the human child is in reality no more than a continuous process of ecphoration of old engrams, one after another. And the entire complex of our living human organism is made up entirely of these energy-complexes engraved on our consciousness or subconsciousness.
But, as a general rule, it may be said that in the development of the embryonal life the process of cell division proceeds in such a way that every germ of the child's future organism represents approximately one-half maternal and one-half paternal substance and energy. In this process lies the true secret of heredity.
In "Nago Mbwiri" the sense is an idol, an object of worship, a "medicine" as the North-American Indians say, in contradistinction to Munda, a grigri, talisman, or charm. Every Mpongwe, woman as well as man, has some Mbwiri to which offerings are made in times of misfortune, sickness, or danger. I afterwards managed to enter one of these rude and embryonal temples so carefully shut.
Darwin relies upon indirect proofs, the bearing of which is real and incontestable"; who concedes that "his theory accords very well with the great facts of comparative anatomy and zoölogy, comes in admirably to explain unity of composition of organisms, also to explain rudimentary and representative organs, and the natural series of genera and species, equally corresponds with many palaeontological data, agrees well with the specific resemblances which exist between two successive faunas, with the parallelism which is sometimes observed between the series of palaeontological succession and of embryonal development," etc.; and finally, although he does not accept the theory in these results, he allows that "it appears to offer the best means of explaining the manner in which organized beings were produced in epochs anterior to our own."
I look upon them as simply the embryos of mature forms, which are capable of propagating themselves in this embryonal state. I have observed these forms in many diseased conditions; many of them in one disease are nothing but the vinegar yeast developing, away from the air, in the blood where the full development of the plant is not apt to be found.
Ahlfeld explains the presence of mammae on odd parts of the body by the theory that portions of the embryonal material entering into the composition of the mammary gland are carried to and implanted upon any portion of the exterior of the body by means of the amnion." Possibly the greatest number of accessory mammae reported is that of Neugebauer in 1886, who found ten in one person.
The "return to the embryonal state of psychic life in the dream" and the observation of Havelock Ellis, "an archaic world of vast emotions and imperfect thoughts," appear to us as happy anticipations of our deductions to the effect that primitive modes of work suppressed during the day participate in the formation of the dream; and with us, as with Delage, the suppressed material becomes the mainspring of the dreaming.

The egg has no nutritive cells; the formation of the primitive band, usually the first indication of the germ, is retarded till the second larval stage is attained; and the embryonal membrane is not homologous with the so-called "amnion" of other insects, but may possibly be compared with the skin developed on the upper side of the low, worm-like acarian, Pentastomum, and the "larval skin" of the embryos of many low Crustacea.
