she struggled towards it , her body still throbbing with sharp bursts of pain , her hand out for that tiny slippery leg , that little foot pumping the air , and then as her hand closed on that soft , slick baby flesh , the darkness came down on her , and against her closed eyelids she saw the anatomy , saw the path of the cells , saw the evolving organs , and the age-old miracle of the cells coming together , forming corpuscles and subcutaneous tissue , and bone tissue , and the fibers of the lungs and the liver and the stomach , and fused with his cells , his power , the dn a merging , and the tiny chains of chromosomes whipping and swimming as the nuclei merged , and all guided by her , all the knowledge inside her like the knowledge of the symphony inside the composer , note after note and bar after bar , and crescendo following upon crescendo .
