1908 M. Yearsley tr. A. Forel Senses of Insects x. 237 It is..a question of a chemical sense which gives the exact relations between the different parts of space... The faculty of smell-by-contact could be called chemaphesthesia and relational smell topochemical sense.
1967 J. H. Sudd Introd. Behaviour Ants ii. 17 Because the antennae are moveable and have sense organs all over the surface it has been suggested that ants can perceive spatial arrangements of chemical stimuli, rather as we can perceive patterns of colour or texture. This is the so-called topochemical sense.
2. Chemistry. [ < German topochemisch (Kohlschütter & Tüscher 1920, in Zeitschr. f. anorg. u. allgemeine Chem. CXI. 193).] Of or pertaining to topochemistry.
