ROYAL INDIAN 3. What are the laws of the loss of charge from an insulated conductor? 1877. If two insulated small spheres a given distance apart repel one another with a force of 144 units, and if in each minute the force is diminished by one-eighteenth of the whole, what proportion of the whole charge will remain on each of the spheres at the end of 20 minutes. 4. State the character of the secular and of the diurnal variations to which the declination needle is subject. Explain how they are experimentally determined. 5. Describe the method employed by Gauss to determine the earth's horizontal magnetic force, and state, with reasons, how many and what experiments are necessary for an accurate result. 6. What is meant by electromotive force? State the laws which determine the strength of current which a battery of given electromotive force will produce in a given circuit, and show with what arrangement of cells the strongest current will be produced. A battery of 24 cells is joined up so as to give the strongest current through a galvanometer whose resistance is 2 ohms, the resistance of each cell of the battery being 0·8 ohms, what is the arrangement of the cells? 7. What is meant by the absolute value of the strength of a current ? Describe some method of determining it. 8. State Kirchhoff's laws relating to the currents and resistances in a compound circuit.

What is the arrangement of Grove's gas battery, and what is it intended to illustrate? Wires are attached to its poles, and their other extremities are first attached to the two poles of a battery which is capable of decomposing water, and are then joined together; describe and explain the action which takes place.

To what class of animals do both belong? Compare the distribution in time of these two forms? 1877. GEOMETRICAL DRAWING. (1.) Monday, 25th June 1877. 2 P.M. to 5 P.M. [N.B.-The constructions should be neat and accurate; they must be strictly geometrical, and particular care should be taken not to efface the lines necessary for the correct solutions. Al lines should be inked in either with common or Indian ink.] 1. Construct an isosceles triangle with a base of 4 inches and a vertical angle of 65°. Construct a square of equal area with the triangle. 2. Describe a circle with a radius of 2.58 inches, and by means of 4 point in the outermost circle draw a tangent to the innermost 3. Construct a scale, in which 5 furlongs are represented by 9 inches, 360° 4. Seven straight lines making equal angles (3) with each other radiate from a common centre. Make these lines respectively, Scale (which need not be drawn), 25 feet 1 inch. 5. In a circle of 24 inches radius inscribe a regular pentagon, and in the pentagon inscribe an equilateral triangle. 6. Determine geometrically the values of 5 and of 7. The plan of an equilateral triangle of 3 inches side is a triangle having 2 of its sides 2 and 1 inches, and the included angle 70°. Determine the scale of slope (or the traces) of the plane ROYAL INDIAN E. COLLEGE, 1877. in which the triangle lies and the inclination of this plane, and of the third side of the triangle, to the horizon. 8. Draw the plan of a right hexagonal prism 4 inches long, of which each side of the base measures 1 inches, supposing one side of the base to rest on the horizontal plane and a face containing that side to be inclined 50° to the horizon. GEOMETRICAL DRAWING. (2.) Saturday, 30th June 1877. 10 A.M. to 1 P.M. 1. Define the term "vanishing point" of a line. Explain where would 2. Draw a line 3 inches long parallel to neither edge of your paper. 4. A cube, 1 inch edge, rests on a horizontal plane. Its nearest of cube, 2 inches. GEOMETRICAL DRAWING. (3.) Saturday, 30th June 1877. 2 P.M. to 5 P.M. 1. The plane of an equilateral triangle, 3 inches side, is inclined at 35°; one of its sides at 20°. Draw the plan. 2. Draw a line parallel to the bottom edge of your paper. This represents the intersection of a vertical and a horizontal plane. From any point in this line draw two lines, one on each side, making with it angles of 45° and 70°. These lines represent the vertical and horizontal traces of a plane. Determine its inclination to both planes. 3. Explain the nature of an isometric projection. In what respects does it differ from a perspective picture? For what purposes would you adopt it? 4. An ink bottle of the form of a truncated square pyramid is made of -inch plate glass; side of base 3 inches; length of sloping edge 2 inches; side of upper section 13 inches. The top is a square prism of the same glass, hinged at one of the far sides. It lies open to its full extent. Draw the isometric projection. ROYAL INDIAN 1877. FREEHAND DRAWING.

STATISTICS. TABLE I.-TABLE OF MARKS.-OPEN COMPETITION OF 1877 FOR THE CIVIL SERVICE OF INDIA. 66 NOTE. The following extract from the Tenth Report of the Civil Service Commissioners refers to a change in the mode of assigning marks :-"It has already "been mentioned as one of the ruling principles of these examinations that no can"didate should be allowed any credit at all for taking up a subject in which he is a mere smatterer. Hitherto we have thought it enough, in conformity with this "principle, to strike out all marks which indicated less than a competent knowledge "of the subject selected; leaving those whose knowledge exceeded, by ever so "little, the minimum of competence, to count all the marks assigned to them. We 66 are of opinion, however, that superficial study may be more effectually discouraged "by allowing no credit for slight knowledge even to those candidates who succeed "in passing beyond it. We propose, therefore, that from the marks of all can"didates alike a number answering to this slight knowledge shall be deducted; "but that it shall be possible, nevertheless, for any candidate who may show "remarkable proficiency in any subject to obtain the full number of marks allotted "to that subject." On this occasion a deduction of 125 has been made from the marks assigned in each subject. |
