3. Give some account of the structures known as gill clefts with special regard to their relationship to the blood vessels, describing the final state of development reached by the latter in the various classes of the Chordata.

4. Write an account of the life history of a moss, and compare it in this respect with a fern and a pine.

5. What are and what do you know of the following: —(1) flame cell, (2) mullerian duct, (3) medusa, (4) velum, (5) archenteron, (6) echinococcus.

6. Give some account of the various forms of excretory organs met with amongst invertebrate animals.

BIOLOGY-PART II.

The Board of Examiners.

1. Give some account of the principal variations of structure and of the methods of reproduction met with amongst the Radiolaria.

2. Write an account of the chief forms of excretory organs met with amongst the various groups of animals included amongst the Vermes.

3. Write a brief account of what is known concerning the reproduction and development of sponges.

4. State what you know of the Rhombozoa.

5. Describe the various modes of reproduction met with amongst the Alga.

(Only four questions to be answered, of which one must be No. 5.)

CHEMISTRY.-PART I.

The Board of Examiners.

N.B.-Describe all reactions in words and also, when you can do so, by means of equations.

1. How may a solution of each of the following salts be prepared? and how does each behave when acidified and heated?-sodium hypophosphite, sodium hyponitrite, sodium hypobromite.

2. Give general formula for two classes of double salts formed by union of sulphates of the alkali metals with the sulphates of the heavier metals; and mention some of the chief members of each class.

3. How may arsenic acid be prepared from the substance usually known as arsenic? How does a solution of an arsenate react with (1) magnesia mixture, (2) silver nitrate, (3) hydrogen sulphide? Compare the behaviour in each case with that of an orthophosphate in similar cir

cumstances.

4. How do solutions of barium hydroxide and hydrogen peroxide react when mixed? How could you recover the hydrogen peroxide after employing it in this way?

5. Compare acetic acid with oxalic acid, having regard to (1) the basicity of the acids, (2) their physical properties, (3) the properties of their calcium salts.

6. Show, by examples, that the terms normal salt and neutral salt are not synonymous.

7. In the natural classification of the elements chromium occurs in the same group as sulphur, and manganese in the same group as chlorine. What compounds of these metals may be held to justify this position? Explain fully.

8. Given an element which is solid at the ordinary temperature and which forms a single volatile hydride whose percentage composition has been accurately determined: by what experiments and reasoning would you ascertain the atomic weight of the element?
