She has small eyes that dart like minnows, set beneath an australopithecine brow--not promising yet, but follow the delicate curve of jawbone to the junction of maxilla and mandible: There, yes, a slight overbite straining at thin lips, punctuating each syllable with a smile. Follow the tapering of the ethmoid bone into cartilage: nose as thin as her lips, as thin as her face suggests her body should be. Study the shifting tectonic plates of zygomatic bone stretching her skin into dimples. Scrutinize her further until capillaries dilate in her flushed cheeks. Now illuminate the whole picture: she's pretty for a specimen. She swims in cross-section through the pages of my sketchbook, sagittal cuts bisecting the y-axis of her frame. Notes in the margins are derivatives, lying tangent to her curves. Science is a socially acceptable form of voyeurism. I was trained as a scientist.
