[
VEE-tr] (n. f.) Behind glass walls that guaranteed a controlled environment, the biochemists tried to do what Mr and Mrs Kornbluth had failed to do in the comfort of their own home: create a Baby K. Should they be successful, it was decided that the story of this
in vitro fertilization would be kept within the
vitreous confines of the lab and not become subject of Thanksgiving Dinner ribbing from future cousins of the unborn Baby K. Keeping cells
in vitro means that they're in glass (it's strictly Latin) but vitreous means made of glass (and that is from the French word vitre, which of course means glass.)
