HUXLEY’S ARTIFICIAL UTERUS. “In Huxley’s dystopian future, children are grown in artificial wombs before being decanted into the world. It described a centrifugal pump that kept a liquid of hog’s stomach extract and fetal foal’s liver moving over the placenta and driving it through a synthetic lung and waste product filter.”
