As the different organs of the system are dependent onthe brain and spinal cord for efficient functional action, and asthe mind and brain are closely connected during life, the formeracting in strict obedience to the laws which regulate the latter,it becomes an object of great importance in education to dis-cover what these laws are, and escape the numerous evils con-sequent on their violation. 396. For healthy and efficient action, the brain should be,primarily, sound; as this organ is subject to the same generallaws as other parts of the body.
