Σελίδα 118 - Tic-tac! tic-tac! go the wheels of thought; our will cannot stop them ; they cannot stop themselves ; sleep cannot still them ; madness only makes them go faster ; death alone can break into the case, and, seizing the ever-swinging pendulum, which we call the heart...
Σελίδα 62 - Hair is a protection from heat and cold, and shields the head from blows. It is found on nearly all parts of the body, except the palms of the hands and the soles of the feet. The...
Σελίδα 77 - The smooth, soft air with pulse-like waves Flows murmuring through its hidden caves, Whose streams of brightening purple rush, Fired with a new and livelier blush, While all their burden of decay The ebbing current steals away, And red with Nature's flame they start From the warm fountains of the heart.

Σελίδα 165 - ... at the instant the word of command is heard. But, after a time, the sound of the word gives rise to the act, whether the soldier be thinking of it or not.
Σελίδα 121 - ... more, because the small arteries. suddenly dilate, the natural moderate contraction of their muscles being superseded by a state of relaxation. In other words, the action of the nerves which cause this muscular contraction is suspended. On the other hand, in many people, extreme terror causes the skin to grow cold, and the face to appear pale and pinched. Under these circumstances, in fact, the supply of blood to the skin is greatly diminished, in consequence of an excessive stimulation of the...
Σελίδα vii - Hygiene, or the laws of health ; the one being essential to the proper understanding of physiology, and the other being its practical application to life. The three are intimately blended, and in treating of the different subjects the author has drawn no line of distinction where nature has made none. This work is not prepared for the use of medical students, but for the instruction of youth in the principles which underlie the preservation of health and the formation of correct physical habits.
