Development varies from fetus to fetus. I had put her on a lofty pedestal, figuratively speaking, and ranked her in certain important attributes considerably higher than man, I worshiped at the feet of the creature I had raised to this height, and, like every true worshiper, and I felt myself unworthy of the object of my worship.
