北緯

北 = 丬 + 匕 : A compass rose. In the Eiffel Tower, Beelzebub tries to build a compass. As a baseplate he uses a piece of wood, on which he sticks the north pike of a compass rose. On the south pike he balances a ladle, which is supposed to adjust itself to earth's magnetic field.

纬 = 纟 + 韦 : Willy Walrus (w) and the silk worm (纟) are surprised how cold it is in the Eiffel Tower (ei3). Not only Willy Walrus, but also the silk worm has to wear leather gloves (韦) to keep warm. It must be because of the high latitude (纬).
