The physiological advantages of the practice of injection are
undeniable, if one thinks of the tremendous waste of human time and
energy occasioned by eating and the digestive process.  Our bodies are
half made up of glands and tubes and organs, occupied in turning
heterogeneous food into blood.  The digestive processes and their
reaction upon the nervous system sap our strength and colour our
minds.  Men go happy or miserable as they have healthy or unhealthy
livers, or sound gastric glands.  But the Martians were lifted above
all these organic fluctuations of mood and emotion.
