Translate into Hindustani : In the man's field. In the boy's book. At the end of the road. At the time of his death. Tell him how to do it. He could not see his way. He wishes very much to come home. You will find it in the place I told you. If he had gone when I wished. him I should not have to go now. He is about years old. 40 It was about this time that the whole of the Do'áb became unable to endure any longer the oppressive taxes and grievous oppression. The people in despair set fire to their houses and stacks, and carrying away their cattle, became wanderers in the world. Upon this the Sultan gave orders that every such peasant should be put to death, and that the whole country should be ravaged and given up to plunder. He even himself marched out for that purpose as if he had been going on a hunting expedition. EXPERIMENTAL SCIENCES. PROFESSOR LIVEING. 1. State the composition of ammonia by volume and by weight. Describe the chief characters of that substance, and explain how to detect it in a compound. How much ammonia is contained in a solution which will exactly neutralize 2450 grs. of sulphuric acid? 2. Describe the preparation of chlorine, and explain the chemistry of it. Show that chlorine, bromine, and iodine are closely related; and state what you know of fluorine, explaining the difficulty of experimenting on it. 3. Given an alloy of silver and copper, what substance would you use to dissolve it, and what would be the chemical reaction in the process of solution? How could you demonstrate the presence of each metal in the solution? 4. If a very intense heat be required explain how it may be obtained, and the, principles which would guide you in making it as intense as possible. 5. State the laws which govern the fusion of bodies by heat. Is fusion usually attended with expansion or contraction? Give examples of both these results. Name some substances which are most infusible, even at the highest temperatures, stating their chemical composition, if compounds. 6. A certain quantity of air measures 19 cubic centimetres when saturated with moisture at 39° C.: what volume will it occupy when perfectly dry at 0° C., the pressure being constant at 760 millimetres, and the tension of aqueous vapour at 39° C. being 52 mm. ? 7. What difference is observed in the effect of radiant heat on rock salt, glass, and alum, when the. source of heat is 1st the sun, 2nd a vessel of hot water? Mention analogous differences in the effects of light on different substances. What relation exists between the absorbing and radiating powers of the same body? Explain how this is proved. 8. Define tension in electricity. Point out the causes which limit the tension in the conductor of a frictional electric machine. Explain how to compare experimentally the tension in two galvanic batteries. 9. Explain by reference to general principles why the heating effect on a wire conducting the current of a galvanic battery depends more on the magnitude and closeness of the plates than on their number. Compare the temperatures produced by equal currents in two wires of which each contains the same quantity of metal, but one is twice as long as the other. 10. Explain the action of the nitric acid in Grove's battery. Name other substances which will answer a similar purpose, the rest of the construction being unaltered. 11. Describe an electrophorus, and explain its action. 12. State the several circumstances on which the force of attraction or repulsion between two magnets depends, and the law of variation of this force. Explain how this law is arrived at, stating the principles of the instrument (if any) used in the determination. EXPERIMENTAL SCIENCES. Afternoon Paper. PROFESSOR ABEL, F.R.S. 1. The variation of the compass for the present year is 20° 25′ W. What does this mean; and how will this statement assist you in finding the true north by means of a magnetic needle, at any locality? 2. The mercury-cups of a pair of voltaic plates. are connected, successively, by means of a wire 10 feet long; by a second, 100 feet long, laid out upon the ground; and by a third, of the same length as the last, but coiled up into a helix. The wires are of equal thickness. Will Will you observe any difference between the sparks which appear upon making and breaking contact, in each instance? If so, describe it, and point out the causes. Why have I specified that the thickness of the wires is alike? 3. Give some illustration of the resemblance in their nature between electricity from the frictional machine, and from a voltaic battery; and state to what you ascribe the great difference between the general effects obtained with electricity from the two sources. 4. Describe the construction and action of a thermopile, and state how you would apply it to render evident a very slight radiation or reflection of heat from a body. 5. I stand upon a sheet of guttapercha and place my hand upon the prime conductor of an electric machine, which is then set in motion. Give a full description of what occurs; and state what will be the result of your approaching a finger to any part of my body. 6. Some iron pipes are to be employed for heating an apartment by steam; others are to be used for conveying the steam to a distant locality with as little loss of heat as possible. Describe how you would proceed to attain each object in the most efficient manner, and give your reasons for the arrangements you adopt. 7. What do you know regarding the origin and phenomena of the trade winds? Supposing that the earth were covered with water, would the direction of the winds be the same as at present? If not, point out some of the circumstances which influence their direction. 8. The same absolute quantity of heat is applied to two similar vessels, the one containing water and the other mercury. What will be the ratio of the temperatures indicated by thermometers placed in the |
