First Edition. Exner's work contains the classic formulation of the mosaic theory of insect vision; his conclusions dominated the field for over seventy years.

"Few if any works have ever made more impression on the subsequent 75 years of a special topic than Exner's Die physiologie der facettierten Augen von Krebsen und Insecten (Smith, Mittler & Smith, eds., History of Entomology, p. 195).

Exner, professor of physiology at the University of Vienna, identified the superficial tangential fibers of the molecular layer of the cerebral cortex ("Exner's plexus"; see G-M 1413); he also was the first to say that there are specialized micro-circuits in the periphery of our vision for detecting movement. The frontispiece of the present work is a microphotograph of a retinal image in the eye of Lampyris spldl. (a species of glow-worm). BM (Nat. hist.) VI, p. 310. Smith, Mittler & Smith, pp. 195, 212.
