SMART, CHRISTOPHER

(1722-71), Eng. poet; his mind gave way, 1751, and in an asylum he wrote his only notable poem, A Song to David. SIMELL, the sensory apparatus, stimulation of which occasions olfactory sensations; consists of end-organs in the olfactory epithelium, which occupies part (in man a small part) of the mucous membrane of the nose. The stimulus consists of vaporized particles which pa from odoriferous substances to the nose. Total anosmia (inability to smell) is not very uncommon; partial anosmia is frequent (e.g.), when due to catarrh or smoking. Congenital inability to smell certain odors only ‘has been recorded, and prolonged stimulation by any odor fatigues the nose for that odor. No satisfactory cla ification of odors has been made; Zwaardemaker suggested the following: (1) Ethereal, (2) Aromatic, (3) Balsamic, (4) Amber-musk, (5) Allyl-cacodyl (e.g., asafcetida), (6) Burning, (7) Caprylic (e.g., cheese), (8) Repulsive, (9) Nauseating.
