In a traditional German lavatory, the hole in which shit disappears after we flush water is way in front, so that the shit is first laid out for us to sniff at and inspect for traces of some illness; in the typical French lavatory, on the contrary, the hole is in the back - that is, the shit is supposed to disappear as soon as possible; finally, the Anglo-Saxon (English or American) lavatory presents a kind of synthesis, a mediation between these two opposed poles - the basin is full of water so that the shit floats in it - visible, but not to be inspected.
