TWILIGHT SLEEP
The so-called “Twilight Sleep,” a modern development, by which the pangs of childbirth are obviated by the administration of drugs or by hypnotic suggestion, has its opponents and defenders. The advantage of a painless childbirth, upon which the mother can look back as on a dream, is evident. The “Twilight Sleep” process has been used with the happiest results both for parent and child. Opponents of this system declare that the use of powerful drugs may injure the child. A method commended is the administration of a mixture of laughing gas and oxygen, which relieves the mother and does not affect the child.
THE NEW-BORN INFANT
The average weight of the new-born child is about seven and a half pounds. It is insensitive to pain for the first few days, and seems deaf (since its middle ears are filled with a thick mucus) for the first two weeks. During the first few days, too, it does not seem able to see. The first month of its existence is purely automatic. Evidences of dawning intelligence appear in the second month and at four months it will recognize mother or nurse. Muscularly it is poorly developed. Not until two months old is it able to hold up its head, and not until three months does voluntary muscular movement put in an appearance. The new-born's first self-conscious act is to draw breath. Deprived of its usual means of supply it must breathe or suffocate. Its next is to suck milk, lest it starve.
HEREDITY
We often find children who offer a striking resemblance to a paternal grandfather, a maternal aunt or a maternal great-grandmother. This is known as avatism. There are many curious variations with regard to the inheritance of ancestral traits. Some children show a remarkable resemblance to their fathers in childhood, others to their mothers. And many qualities of certain individual ancestors appear quite suddenly late in life. Everything may be inherited, from the most delicate shadings of the disposition, the intelligence and the will power, to the least details of hair, nails and bone structure, etc. And the combination of the qualities of one's ancestors in heredity is so manifold and so unequal that it is extremely difficult to arrive at fixed conclusions regarding it. Hereditary traits and tendencies are developed out of the energies of the original conjugated germ-cells throughout life, up to the very day of death. Even aged men often show peculiarities in the evening of their life which may be clearly recognized as inherited, and duplicating others shown by their forbears at the same period of life.
As has already been mentioned every individual inherits, generally speaking, as much from his paternal as from his maternal progenitors. This in spite of the fact that the tiny paternal germ-cell is the only medium of transmission of the paternal qualities, while the mother furnishes the much larger egg-cell, and feeds him throughout the embryonic period.
THE ENGRAM
An interesting theory maintains that the external impressions made upon an organism which reacts to them and receives them, might be called engrams or “inscriptions.” Thus the impression of some object we have seen or touched (let us say we have seen a lion) may remain engraved on our mind as an impression. Hence every memory picture is one of engrams, whether the impression is a conscious one or an unconscious one. According to this same theory the reawakening of an older impression is an ecphory. 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. The sum total of all these engrams, in a living human being, according to the theory advanced, is given the name of mnema. That which the child receives in the way of energies contained in the germ-cells from its ancestors is his hereditary mnema. And that which he acquires in the course of his own individual life is his acquired or individual mnema.
