If a liquid he heated at the bottom, how is the heat distributed through the liquid. If heated at the top, how is the heat propagated? 15. State what you know regarding the causes of wind, rain, and dew. 1868 16. Describe the manner in which sound is propagated through air, water, or wood. 17. How are musical sounds produced? On what do the pitch and the intensity of a musical sound depend? 18. How many vibrations per second are necessary for the formation of sound-waves 3 feet in length. 19. How are echoes produced? State all you know regarding the law which regulates the production of echoes. 20. State what you know regarding the structure of the human eye. 21. State what you know regarding the form and use of spectacles. 22. State what you know regarding the production of the colours of flowers. Why, for example, is a rose red, and grass green? 23. A cloud is composed of transparent water particles; but, if trans parent, why are clouds able to intercept so much of the sun's light? 24. What is the velocity of light, and how has it been ascertained? 25. By what means do we ascertain that one light has 8 or 10, or any other number of times the intensity of another? 26. Explain the construction of the common mercurial thermometer, and state how the thermometers of Fahrenheit, Eeaumur, and the Centigrade thermometer, are graduated. 27. What is meant by the boiling point of a liquid? What is the boiling point of water, and how could water be heated above its ordinary boiliug point? How is the boiling point affected when we ascend a mountain? 28. I heat a ball of lead and one of iron to the temperature of boiling water...
