Masses m and m1, when suspended in water from the two arms of a balance, equilibrate each other; the density of the first mass is d; find that of the other.

6. Explain fully how the weight thermometer is constructed and used, and give its theory.

7. Describe the apparatus you would use and the experiments you would perform with it in order to compare the diathermancies of glass and rock salt.

8. Describe the construction, and explain the action of some form of frictional electrical machine.

9. State the Laws of Electrolysis, and give an account of the experiments by which Faraday demonstrated them.

10. Describe, and explain the action of, a carbon telephone transmitter.

CHEMISTRY.-PART I.

The Board of Examiners.

N.B.-Candidates should write equations where possible; but an equation by itself, without verbal description, is not accepted as evidence of knowledge.

1. How would you proceed if you wanted a sample of chemically pure water and your only supply were derived from a dirty pond? Describe the mode of each operation and its results.

2. How would you distinguish from one another samples of the potassium salts of hydrochloric, chloric, and perchloric acids?

3. Describe Reinsch's and Marsh's tests for Arsenic, and explain the reactions involved in them.

4. Sulphuretted hydrogen gas is passed into a certain solution already acidified with hydrochloric acid, and a precipitate is formed which proves to be sulphur. Name some of the substances whose presence in the solution may be suspected, and explain how each would produce the observed result.

5. Describe the chief physical and chemical characters of magnesium.

6. What is the difference between a paraffin, as chemists use the term, and paraffin, as generally understood?

7. Explain fully what you understand by chemically equivalent weights of different acids.

CHEMISTRY.-PARTS II. AND III.

The Board of Examiners.

1. Describe an instance in support of the statement that crystalline form may give aid in the determination of atomic weights.

2. Explain and comment upon the statement that Avogadro's law is obeyed by substances in the state of dilute solution.

3. Discuss the behaviour of indicators towards acids and alkalis from the stand-point of the ionic theory.

4. Describe any actual case of the investigation of the velocity of a chemical change in which such investigation has thrown light on the nature of

the action.

5. Explain fully the terms-heat of formation and heat of combustion, as applied to particular substances.

6. Describe and explain the mode of action of potassium bichromate, and some of its uses in volumetric analysis.

7. Give a short account of the chemistry of thallium, and discuss its place among the elements.

TECHNICAL CHEMISTRY.
