In the organs of touch the nerve-cell is found in theganglion of the posterior spinal nerve-root; the peripheral process is very long and is acted fm indirectlythrough the modified epithelium round which it clusters. The same may be said of the other senseorgans. See Quains Anatomy, 10th ed., vol. iii. pt. 3, p. solution containing it. Thus, when 1 part of common salt to 213 of waterwas tasted by Valentin/ 11 c
