of adrenin is specific—The point of action of
adrenin in muscle | [110]–134 |

| |
| CHAPTER X | |
| THE HASTENING OF COAGULATION OF BLOOD IN
PAIN AND GREAT EMOTION | |
| Coagulation hastened by splanchnic stimulation—Coagulation
not hastened by splanchnic stimulation if
the adrenal glands are absent—Coagulation hastened
by “painful” stimulation—Coagulation hastened
in emotional excitement | [161]–183 |
| |
| |
| CHAPTER XI | |
| THE UTILITY OF THE BODILY CHANGES IN PAIN
AND GREAT EMOTION | |
| The reflex nature of bodily responses in pain and the
major emotions, and the useful character of reflexes—The
utility of the increased blood sugar as
a source of muscular energy—The utility of increased
adrenin in the blood as an antidote to the
effects of fatigue—The question whether adrenin
normally secreted inhibits the use of sugar in the
body—The vascular changes produced by adrenin
favorable to supreme muscular exertion—The changes
in respiratory function also favorable to great effort—The
effects produced in asphyxia similar to those
produced in pain and excitement—The utility of
rapid coagulation in preventing loss of blood | [184]–214 |
| |
| |

competitive sports—Frenzy and endurance in ceremonial
and other dances—The fierce emotions and
struggles of battle—The stimulating influence of
witnesses and of music—The feeling of power | [215]–231 |

| CHAPTER XIII | |
| THE NATURE OF HUNGER | |
| Appetite and hunger—The sensation of hunger—The
theory that hunger is a general sensation—Weakness
of the assumptions underlying the theory that
hunger is a general sensation—Body need may exist
without hunger—The theory that hunger is of general
origin does not explain the quick onset and the
periodicity of the sensation—The theory that hunger
is of general origin does not explain the local reference—Hunger
not due to emptiness of the stomach—Hunger
not due to hydrochloric acid in the empty
stomach—Hunger not due to turgescence of the gastric
mucous membrane—Hunger the result of contractions—The
“empty” stomach and intestines contract—Observations
