What are the substances contained in the tubes A, B, and C ?

If round an electromagnet, a quantity of insulated wire be coiled, in the same way as the coil of the magnet itself, and the ends of this wire be connected with the terminals of a multiplying galvanometer, describe what takes place, when a current is sent round the coil of the magnet, and when this current is stopped.

Explain how a person may be knocked down in a thunderstorm without being actually struck by lightning.

Define the specific heat of a body.

If 100 grammes of iron be boiled for some time in water, when the height of the barometer is 760 m.m., and be then quickly transferred to a vessel containing 150 grammes of water at $10^{\circ }$C, what will be the common temperature of the iron and water ? It being assumed that no heat is lost, that a gramme of hot water adheres to the iron when it is transferred to the cold water, and that the specific heat of iron is 0.114.

Describe the common thermometer, and the way in which it is graduated.

To what change is a thermometer liable, which produces errors in the indications of the instrument ?

Describe the way in which an image of an object is. formed by a convex lens, and state the relation between the distances of the object and image from the lens.

In what way is the eye enabled to produce, upon the retina, distinct images of objects at different distances from it ?

How are differences of quality in musical sounds of the same pitch accounted for ?

Describe briefly the apparatus in the human ear which, it seems probable, is employed in producing the sensation of quality in musical sounds.

Enunciate Boyle's law connecting the volume and tension of a gas.

Explain the process of respiration, as far as it is due to the motion of the Diaphragm.

Assuming the lungs to contain 1600 cubic centimetres of air at the termination of an expiration, and 400 cubic centimetres to be introduced by each inspiration, if, after an expiration a vertical tube be placed in the mouth, with its lower end dipping in mercury, and, the nose being stopped, the act of inspiration be performed, to what height will the mercury rise in the tube ? The height of the mercury in the barometer being 760 m.m., and the air in the tube being neglected.

Describe some experiment illustrating the property, possessed by a fluid, of transmitting pressure applied to it equally in all directions.

If a body falls in vacuo, express the velocity, and the distance of the body from the starting point, at any instant in terms of the time which has elapsed since motion commenced.

Account for the comparatively small velocity of a drop of rain when it reaches the earth, and state what is the effective force upon the drop at that time.

When a force produces motion in a body, how is the work done expressed in terms of the force and the circumstances of the motion ? Explain generally the appropriateness of this expression.

When a man walks along a horizontal road, in what way does he perform work ?

If two parallel forces act upon a rigid body in opposite directions, state how to determine the magnitude and position of their single resultant.

Discuss the case in which the two forces become equal in magnitude.

Describe the arrangement and action of the muscles by which the motion of the eye-ball is produced.
