PHYSICAL GEOLOGY AND MINERALOGY.

The Board of Examiners.

1. Describe fully the various considerations influencing the general opinion of modern geologists as to the original condition of the earth, and all its changes influencing its present shape, density, relative position of rocks, and surface physical features.

2. Give as many illustrations as you can illustrative of the suggestions of relation between compassbearing and geological age of mountain chains and of mineral veins.

3. In what respects do Isomorphism, Dimorphism, Trimorphism, Holohedral, and Hemihedral developments, Twins and Macles, interfere with the ordinary laws of Crystallography?

Give as many accurate examples as you can of each in different systems of crystallisation.

4. Explain the general circumstances governing the formation, composition, relation to other minerals, and place of occurrence of Zeolites.

5. Write down the notation for as many forms as you can, according to the methods of Weiss, Miller, and Naumann, of secondary forms in the different systems of crystals.

STRATIGRAPHICAL GEOLOGY AND

PALEONTOLOGY.

The Board of Examiners.

1. Write down in as full detail as you can, and in proper order of superposition, all the stratigraphical divisions of the crust of the earth recognised by modern geologists.

2. Give in as full detail as you can, the characteristic fossils of all the subdivisions of the Tertiary series of rocks, with the generic characters of all the genera you mention of Marine and Freshwater Mollusca.

3. Give the generic characters of as many as you can of the genera of Mammalia found in the Eocene, Miocene, Pliocene, and Modern Formations.

4. Mention as many as you can of the characteristic fossils of (a) the so-called Laurentian; (b) the St. David slates; (c) the Lingula flags, and Skiddaw slates; (d) the Bala beds; (e) the Mayhill sandstone; (f) the Wenlock limestone.

BIOLOGY.

FIRST PAPER.

The Board of Examiners.

A few questions fully answered will count more than a larger number imperfectly answered. All answers must, where possible, be illustrated by rough sketches.

1. Write a short essay on the structure and affinities of the Hirudinea.

2. Give an account of the structure and relationships of Cephalodiscus.

3. Describe carefully the anatomy and life history of the Larvaceæ, pointing out how far they resemble the larval forms of other members of the group Urochorda.

4. Give a comparative account of the structure of the eye in invertebrate animals other than Arthropods; or, give an account of the structure of the eye in the Arthropoda.

5. Describe the origin, structure, and ultimate fate of the notochord in the Urochorda, Cephalochorda, Pisces, and Amphibia.

6. Give the characters of the two chief groups in the Cephalopoda, and an account in detail of the structure of Nautilus.

7. Give an account of the various respiratory organs met with in the group Arthropoda.

8. Write a short essay on the various forms of the suspensorium of the mandible in the Craniata.

SECOND PAPER.

The Board of Examiners.

A few questions fully answered will count more than a large number imperfectly answered. All answers must, where possible, be illustrated by rough sketches.

1. Write an account of the blood vessels connected with the branchial arches in the classes Pisces and Amphibia.

2. Describe in detail the structure of Peripatus, pointing out its affinities to other forms.

3. State and explain briefly the main points of structure in which the Eutheria differ from the Metatheria and Prototheria respectively.

4. Give an account of the structure, classification, and affinities of the Polyzoa.
