Страница 290 - We must make new energies and hardihoods continue the manliness to which the military mind so faithfully clings. Martial virtues must be the enduring cement; intrepidity, contempt of softness, surrender of private interest, obedience to command, must still remain the rock upon which states are built...
Страница 290 - ... feel some degree of it imperative if we were conscious of our work as an obligatory service to the state. We should be owned, as soldiers are by the army, and our pride would rise accordingly. We could be poor, then, without humiliation, as army officers now are. The only thing needed henceforward is to inflame the civic temper as past history has inflamed the military temper. HG Wells, as usual, sees the center of the situation.

Страница 35 - From the medulla can be extracted a substance, called variously suprarenin, adrenin, epinephrin, or "adrenalin," which, in extraordinarily minute amounts, affects the structures innervated by the sympathetic division of the autonomic system precisely as if they were receiving nervous impulses. For example, when adrenin is injected into the blood, it will cause pupils to dilate, hairs to stand erect, blood vessels to be constricted, the activities of the alimentary canal to be inhibited, and sugar...
Страница 221 - Some sunk down, and there remained no strength in them ; others exceedingly trembled and quaked ; some were torn with a kind of convulsive motion in every part of their bodies, and that so violently that often four or five persons could not hold one of them.
Страница 22 - The preganglionic fibers of the autonomic system are in solid lines, the postganglionic in dash-lines. The nerves of the cranial and sacral divisions are distinguished from those of the thoracico-lumbar or "sympathetic
