Just as the expansion in the New Army and the New Navy has made it possible for unknown enemy agents to take service in the Army and the Navy, so the dilution of labour in the shipyards has made it possible for workmenwhose sympathies are with the enemyto get employment about the warships.

Each of these is the echo in the mind of cells stimulated or depressed, by concentration or dilution in the blood of particular internal secretions.

This new old experience of battle and peril you apply without dilution to your soul, and you wonder what the effect will be.
