Each of these ten stimulates a neighboring ten, and so on by geometrical proportion, until the influence of the original stimulus fades away. Such stimuli are normally brought to these cells in the grey cortex (bark) by the nerve fibres. These form the white core of the brain. (Naturally there are blood vessels and a variety of other cells in the brain as elsewhere in the human economy...

There the grey cells in the cortex mull the influences of these stimuli, play with them, sometimes bury them as memories. If a physical reaction is wanted, consciously or subconsciously, the brain sends out its will by way of efferent nerves to the organs of expression, to the limbs, the viscera, the tongue, the hand...

These must be supplied by those who teach. Indeed, the college like the individual must seek its strength within itself...
