A double coil of wire at thespring end renders the speculum so elastic as to rarely causepain while in position; as a further result of this double coil,the instrument has a slight antero-posterior motion, thus allow-ing the septal blade to be drawn forward in front of the sensitive,bony septum, while the alar blade is well introduced for morecomplete dilatation of this portion.
