5. Give a short account of the allotropic forms of carbon. How can it be proved that they are only different forms of the same elementary substance ? 6. Show by a comparison of their chemical and physical properties that chlorine, bromine, and iodine may reasonably be regarded as members of the same family of elements. 7. When hydrogen and chlorine are exploded no permanent change of volume is produced. What theoretical deduction as to the molecular state of chlorine and of hydrogen can be made from this observation ? 8. How is sulphuric acid manufactured ? What is the action of the cold dilute and the hot concentrated acid upon zinc, copper, and potassium ferrocyanide respectively ? 9. Give a short account of the chemistry of arsenic, and explain any method whereby the presence of arsenic in a solution may be detected.

What modifications of the cell would you find in (a) the vascular bundle, (b) the parenchyma of the stem, and (c) the epidermis ? 2. What are the chemical elements necessary for the building up of new living plant material ? How and whence does a green plant obtain these various substances ? 3. Describe carefully a complete transverse section of the stem of such a plant as the bean (or any other with which you are familiar). State the functions of all the various structures you describe. 4. Give an account of the anatomy of any flower with which you are familiar. Point out the functions of the various parts as far as you can. 5. Write an account of the structure of a fully developed ovule. What changes take place in it on becoming a seed, and what starts these changes ? 6. State in general terms what you understand by a fruit. Describe in technical language the fruit of the following: Bean plant, buttercup, daisy, cherry, gooseberry ; and indicate clearly what parts of the flower are involved in each instance. 7.

Music. — Time allowed : 3 hours. Instbuctioss to Candidates. (a.) For the sake of uniformity it is requested that the notes of the scale be referred to by their Tonio Sol-fa names —Doh, Ray, Me, Pah, Sob., Lah, Te—or their initial letters. (b.) The Tonic Sol-fa terminology is used throughout this paper as being the more generally known among school teaohers; but, where considered necessary, explanations iv ordinary musical language are given in brackets, thus:' " Three-pulse measure [Triple time]." (c.) Answers requiring the use of the staff notation may be written in their proper place in the body of the paper, candidates ruling their own staves. i (d.) AU candidates are expected to attempt the practical work (Question 13). The time and tune tests may be taken in either notation. 1. Describe briefly the construction of the diatonic major scale, and draw a modulator [scale diagram] of one octave to illustrate it. 2. In what order would you teach the tones of the Doh chord ? In what order would you subsequently add the remaining tones of the scale ? 3. Mention some of the causes of flat singing, and say how you would deal with.this difficulty in classes of children. 4. How would you begin the important subject of ear training? 5. By what means would you endeavour to get sweetness and good tone in school singing?
