We think it necessary to adopt the following:— 1. General idea of the function. 2. Circumstances which put the action of the organs into play, and which we call excitants of the functions. 3. Summary anatomical description of the organs that concur in the function, or of the apparatus. 4. Study of every action of the organ in particular. 5. General recapitulation, shewing the utility of the function. 6. Relations of the function with those already examined. 7. Modifications which the function presents, according to age, sex, temperament, climate, seasons, habit. OF THE FUNCTIONS OF RELATION. Functions of relation. The functions of relation are composed of sensation, standing, of the voice, and of motion. of under OF SENSATION. ofthesensa- The seiisations are functions destined to receive the impres¬ sions of external objects, and to transmit them to the under¬ standing. The number of these functions is five :—vision, hearing, smell, taste, touch. OF VISION. Of vision.
