Yes, there were differences. We rarely confused one with another. It was second nature for me to distinguish Edward from Albert, George from Philip, Frederick from Stephen. And Mother never confused us.
She was a regal woman, nearly six feet in height, who even in middle age had retained straightness of posture and majesty of bearing. Her eyes, like ours, were blue; her hair, she told us, had once been golden like ours. Her voice was a deep, mellow contralto; rich, firm, commanding, the voice of a strong woman. She had been Professor of Biochemistry at some Eastern university (she never told us which one, hating its name so) and we all knew by heart the story of her bitter life and of our own strange birth.
"I had a theory," she would say. "It wasn't an orthodox theory, and it made people angry to think about it, so of course they threw me out. But I didn't care. In many ways that was the most fortunate day of my life."
"Tell us about it, Mother," Philip would invariably ask. He was destined to be a playwright; he enjoyed the repetition of the story whenever we were together.
She said:
"I had a theory. I believed that environment controlled personality, that given the same set of healthy genes any number of different adults could be shaped from the raw material. I had a plan for testing it—but when I told them, they discharged me. Luckily I had married a wealthy if superficial-minded executive, who had suffered a fatal coronary attack the year before. I was independently wealthy, thanks to him, and free to pursue independent research, thanks to my University discharge. So I came to Wisconsin and began my great project."
We knew the rest of the story by heart, as a sort of litany.
We knew how she had bought a huge, rambling farm in the flat green country of central Wisconsin, a farm far from prying eyes. Then, how on a hot summer afternoon she had gone forth to the farmland nearby, and found a fieldhand, tall and brawny, and to his great surprise seduced him in the field where he worked.
And then, the story of that single miraculous zygote, which our mother had extracted from her body and carefully nurtured in special nutrient tanks, irradiating it and freezing it and irritating it and dosing it with hormones until, exasperated, it sub-divided into thirty-two, each one of which developed independently into a complete embryo.
