Of the stimuli applied to the sensory apparatus, physiologists distinguish two kinds: (a) Homologous
stimuli, which act only upon the end organ, and for whose action the sense organs are especially adapted,
as the rods and cones of the retina for the vibrations of the either. (b) Heterologous stimuli, which are
mechanical, chemical, electrical, etc., and act upon the nervous elements of the sensory apparatus along
their entire course, producing, for example, the flash of light beheld when the eye is struck. Landois &
