From those competitors who attain the minimum amount of marks, and satisfy 
the requisite conditions in other respects, the Secretary of State will select those 
whom he may deem best adapted to the Service. 
The candidates so selected will undergo a course of two years’ special training 
at Cooper’s Hill College, commencing with the annual session, which begins in 
September. 
Under the new scheme which wil] come into force next year, the subjects of 
examination will be divided into three classes, namely :— 
I. Obligatory subjects, in which a candidate must obtain one-third of full marks 
in order to qualify :—

Lower Mathematics (as defined in peared) : : - 2,000 
English Composition . a c “ : . 1,000 
German (400 for colloquial) . - : . sia aieke - 2,000 
II. Optional subjects, of which a candidate may offer two, but not more than 
two :—

ELEMENTS OF CHEMISTRY. ' 
1. Give an account of the composition and properties of the substance produced , 
by burning sulphur in air. ’ 
2, What are the relative densities of oxygen, carbon dioxide, and water vapour, 
at the same temperature and pressure? Explain by reference to general laws why 
in a mixture of such gases and vapour the most dense does not sink to the bottom. 
3. Describe the chief characters of nitrogen, and show how to obtain pure 
nitrogen. How can you prove that ammonia contains nitrogen ? 
4. Describe and explain the preparation of nitric acid. Explain the action of 
strong, and of dilute, nitric acid on zine. 
5. What sort of substances can be removed from water by (1) filtration, 
(2) distillation? Given a sample of water, how could you test whether it had — 
been distilled? How is water affected by having carbonic acid in it ? ' 
6. Explain how sodium silicate is made, and how a solution of silicic acid can 
be obtained from it. 
7. What do you understand by neutral and acid salts respectively? Give 
examples of each kind. If a solution of sulphuric acid will dissolve 20 grams of | 
calcium carbonate and no more, calculate the amount of sulphuric acid in the — 
solution. (0:S:C: Ca=16: 32:12:40.) ; 
8. State the chemical composition of alum, blue vitriol, epsom salt, potassium 
permanganate, and corrosive sublimate; and mention uses to which they are 
applied.
