This last...

Page 16 - With other ministrations thou, O Nature ! Healest thy wandering and distempered child: Thou pourest on him thy soft influences, Thy sunny hues, fair forms, and breathing sweets; Thy melodies of woods, and winds, and waters ! Till he relent, and can no more endure To be a jarring and a dissonant thing Amid this general dance and minstrelsy; But, bursting into tears, wins back his way, His angry spirit healed and harmonized By the benignant touch of love and beauty.

Page 156 - ... by the necessity for a supply of carbon and hydrogen to support his respiration, this want may be most advantageously fulfilled by the employment of a certain quantity of non-azotized food, in which these ingredients predominate. Thus it has been calculated that, since fifteen pounds of flesh contain no more carbon than four pounds of starch, a savage with one animal and an equal weight of starch, could support life for the same length of time during which another restricted to animal COMPOSITION...
Page 286 - Promote the warmth of the body by the application of hot flannels, bottles, or bladders of hot water, heated bricks, &c., to the pit of the stomach, the arm-pits, between the thighs, and to the soles of the feet.
Page 13 - we have examples of the compatibility of even the heat of boiling water with the preservation of animal life. Thus in a hot spring at Manilla, which raises the thermometer to 187°, and in another in Barbary, whose usual temperature is 172°, fishes have been seen to flourish. Fishes have been thrown up in very hot water from the crater of a volcano, which from their lively condition, was apparently their natural residence.
Page 537 - The building instinct showed itself immediately it was let out of its cage and materials were placed in its way ; and this before it had been a week in its new quarters. . Its strength, even before it was half grown, was great.
Page 3 - So directly, however, is infant life influenced by good or bad management, that, about a century ago, the workhouses of London presented the astounding result of twenty-three deaths in every twentyfour infants under the age of one year. For a long time this frightful devastation was allowed to go on, as beyond the reach of human remedy. But when at last an improved system of management was adopted in consequence of a parliamentary inquiry having taken place, the proportion of deaths was speedily...
Page 430 - One particular only, though it may appear trifling, I will relate.
