Page 285 - This aqueous vapour is a blanket more necessary to the vegetable life of England than clothing is to man. Remove for a single summer-night the aqueous vapour from the air which overspreads this country, and you would assuredly destroy every plant capable of being destroyed by a freezing temperature.
Page 366 - cyclone " and " anticyclone " do not describe phenomena that can be observed by one observer or at a single station, they should, therefore, not be used in the description of local phenomena ; they represent generalisations based upon the charting and study of winds and clouds observed at many stations, and should only be used when the nature of the rotation of the winds has been clearly demonstrated or can be safely inferred. The terms " cyclonic winds," " cyclonic system," and " cyclonic rotation...
Page 285 - No doubt, therefore, can exist of the extraordinary opacity of this substance to the rays of obscure heat ; and particularly such rays as are emitted by the earth after it has been warmed by the sun.
Page 285 - Remove for a single summer-night the aqueous vapour from the air which overspreads this country, and you would assuredly destroy every plant capable of being destroyed by a freezing temperature. The warmth of our fields and gardens would pour itself unrequited into space, and the sun would rise on an island held fast in the iron grip of frost.
Page 264 - Every particle of matter, in the universe, attracts every other particle with a force, which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Page 351 - In whatever direction a body moves on the surface of the earth, there is a force arising from the earth's rotation which deflects it to the right in the northern hemisphere, but to the left in the southern hemisphere.
Page 313 - TJiefucl value of food. — Heat and muscular power are forms of force or energy. The energy is developed as the food is consumed in the body. The unit commonly used in this measurement is the calorie, the amount of heat which would raise the temperature- of a pound of water 4° F.
Page 102 - Venus, like our moon, rotated on its axis in the same time that it revolves around the sun, and therefore always presented the same face to the sun.
Page 334 - Procure a thick glass tube about thirty-six inches long and closed at one end. Fill the tube with mercury ; place your thumb over the open end ; invert the tube ; place the open end in a cup of mercury and take away your thumb. A column of mercury will be supported in the tube by the pressure of the atmosphere. The distance between the top of the column and the surface of the mercury in the cup will be about thirty inches.
