3. Fluorine, Chlorine, Bromine, and Iodine are said

to form a natural family. State why.
4. If you were given an alloy of silver and copper, how

would you determine the percentage of each
metal present ?

5. 2.4 grammes of magnesium was heated in a com

bustion tube, and a current of dry hydrogen
chloride was passed over it until the whole of the
metal was converted into chloride. The hydrogen
evolved was measured at a pressure of 779 m.m.,
and temperature of 14° C. * Calculate its volumé
under these conditions; and also the weight of
each product of the reaction.

6. Describe how the following metals are extracted

from their ores, and give their chief physical and
chemical properties: Zinc, lead, and tin.

1. A 32-lb. shell, travelling with a speed of 500 feet

per second separates, on bursting, into two
fragments of 20 and 12 lbs. each. The heavier
travels forward with a speed of 1,600 feet per
second; find the amount and direction of the
velocity of the smaller piece. Calculate also the
change of kinetic energy in the act of bursting.

2. State the third law of motion, and describe any

experiments by which it might be directly verified.

3. The specific gravity of pure gold is 19.265, of

copper 8.945, of standard gold 18.405. Find the proportion of copper in standard gold.

4. Describe and give the full theory of some good

method of determining the coefficient of expansion of a liquid.

5. How would you determine the specific heat of a

liquid (such as alcohol), which evolves heat when mixed with water? Give a complete account of

the method you would adopt, and give its theory. 6. Explain clearly what is involved in the statement

that“ the dynamical specific heat of water is 42

million ergs."

7. Describe some method (graphical or other) for deter

mining the relative strength and direction of the magnetic field at different points near to a bar magnet.

8. Shew that electrification is measurable, and explain

the term unit of electric quantity.

Two small spheres, each of mass one gramme, are placed at a distance of 5 cm. apart, and each receives a positive charge of 2 units; what is the initial relative acceleration with which they begin to separate ?

2. Describe the minute structure of the Retina. What

are its functions ?

3. What is Glycogen ? Where and how is it formed,

and what are its uses ?

4. Contrast the digestive systems of fish, amphibia, and

mammals.

ledon, with the functions of its parts.

4. (a) What are the chief uses of the stipules, the

petiole, and the veins of leaves ? Give examples. (6) Describe the different kinds of phyllotaxis of

dicotyledons. Why is the opposite form believed to have been the original one, and how may

the others have been derived from it?

5. Describe the development of the ovule of an angio

sperm, and the process by which it becomes a seed.
