So that we now know Fig. Microscopic Structure of Antenna, after Schiemenz. n Nerves. c Cells. h Tooth hairs. / Pits or pori. that the antennae, in most insects at least, contain the organs of smell. Histologically this apparatus is found to con- sist of nerves (Fig. lo, n) which run from the brain to the antennae and at the outer, sensitive end, contain a cell (Fig. II) with one or more nuclei. These nerves may end in perforated, tooth-like hairs on the antennae (Fig. II, '^) in pegs which have no chitinous sheath, which push out from the bottom of pits—pori, which exist often in great numbers in the antennae (Fig. ii). While Erichson first discovered the pits (Fig. ii, p) in the antennae, Burmeister discovered the sensitive nerve-ending.
