suit the majority of those attending it. Fifty Lectures will be delivered on the more advanced problems of Metaphysical and Ethical Thought, treated both analytically and historically, with special reference to the Honours M.A. Degree Examination in Philosophy. Other Meetings of the Class will be held at separate hours for the discussion and examination of Problems.

This Class is designed to meet the wants of students specially interested in Philosophy, and of those who are studying for Honours in the Department.

It may also be found of use to students of Theology who have passed through the Ordinary Class, and who are studying at St Mary's College.

NATURAL PHILOSOPHY.

This Professorship is coeval with the foundation of the Colleges. The Professor is appointed by the University Court.

Students are recommended to attend the Class of Natural Philosophy during the Session immediately succeeding attendance at the Second Mathematical Class.

There will be four courses of instruction in the Class of Natural Philosophy during next Session.

1. Ordinary Class.-An elementary course of 100 Lectures embracing Mechanics, Heat, Light, Sound, Properties of Matter, Electricity, and Magnetism. This is the Ordinary Class required of Candidates for the Ordinary and Honours Degree in Arts.

2. Honours Class.-An advanced course of 60 Lectures suited for Students desirous of taking Honours. The subject of the course will be the Physical Theory of Light. Attendance on this Class is required of Candidates for the Degree of M.A. with Honours in Natural Philosophy and for the Final Examination in Science. There will also be a number of lectures, about 30, on the application of the Differential and Integral Calculus to Dynamics.

3. Two courses of training in Practical Physics, one elementary and the other advanced. Each member of the Class attending this course will receive at least 60 hours' instruction.

The Ordinary Class will receive during the Session twelve Examination Papers, the answering of which is optional in the case of four only.

The Honours Class will be examined at least twice during the Session.

The Practical Classes will be examined at least twice during the Session.

The Text-books for the Ordinary Class are (1) Lodge's Elementary Mechanics. (2) Ganot's Physics or Watson's Text-book of Physics. (3) Schuster's Practical Physics. (4) Printed notes. The Text-book for the Lectures delivered to the Honours Class will be Preston's Theory of Light. Practical work in the Honours Class will consist of measurements in the Properties of Matter, Light, Heat, and Electricity. Printed notes are supplied to Students.

The Class medal will be awarded to the Student who, in the opinion of the Professor, shows most proficiency in the written Examinations, in solving Problems, and in Practical Physics.

Preparatory Study for Ordinary Class.-Ganot's Physics, or Deschanel's Elements of Natural Philosophy.

Neil Arnott Fund.

This fund consists of a sum of £1000, presented to the University in 1874 by Mrs Arnott, in memory of her husband, Dr Neil Arnott, to be termed the Neil Arnott Fund, and to be devoted to the promotion of the Experimental Study of Natural Philosophy.

In terms of the deed of foundation, the free annual income of the fund is expended in the purchase of Apparatus for the Natural Philosophy Class.

MATHEMATICS.

This Professorship was founded in 1668. The Professor is appointed by the Crown.

There are four Mathematical Classes.

The Junior Class meets one hour daily for five days in the week. The subjects are: Geometry Euclid, Modern Geometry, Elementary Algebra and Trigonometry, and the use of Logarithms.

A Tutorial Class, open to members of the Class, meets three times a-week for the benefit especially of those who are backward, and attendance on it is required from all who make less than 50 per cent in the Examinations.

Text-books.-Mackay's Euclid, C. Smith's Elementary Algebra, and Loney's Trigonometry.

The Ordinary Class meets one hour daily for five days in the week, and is the qualifying Class for the Ordinary Degree of M.A., and for the First Science Examination. The subjects are -Algebra, Plane Trigonometry, Analytical Conics. A Tutorial Class, open to every member of this Class, meets twice a-week.

Text-books.-C. Smith's Treatise on Algebra, Loney's Trigonometry, and Smith's Conic Sections, or any other good treatise.

Junior Honours Class.-A course of about eighty Lectures will be delivered upon the Elements of the Differential and Integral Calculus and Co-ordinate Geometry.

Text-books.-Edwards's Differential Calculus for Beginners; Edwards's Integral Calculus for Beginners.

Senior Honours Class. Courses equivalent to about fifty Lectures by the Professor and the Assistant Professor will be delivered upon the higher parts of the Differential and Integral Calculus or on Differential Equations.

Text-books.-Edwards's Differential Calculus, Williamson's Integral Calculus, Forsyth's Differential Equations.

In the Junior, Ordinary, and Junior Honours Classes oral Examinations are held daily, and written Examinations every fortnight. Every Student who attends any one of the Mathematical Classes a second time will be allowed to compete for prizes under deduction of 8 per cent of the marks he makes if he was in the first rank of Honours during his previous attendance, and of 5 per cent if below that rank.

The Mathematical Class Library.-Founded at the close of Session 1882-83, for the use of Students attending the Mathematical Classes. It is suggested that any one interested in the University, and possessing books, however old or shabby, connected with Mathematics or Natural Philosophy, for which they have no special use, might present them to the Class Library.

Subjects prescribed for Summer Study.

In both the Junior and Ordinary Classes two papers will be set, one on the work done during last Session, and the other on the work prescribed below. The former paper is for all Students who were not in the first rank of Honours, and every one who makes 60 per cent or upwards will receive a prize. The second paper is open to the whole Class, or to any Student who has previously attended it but has not been in a higher Class. The examinations will be on Monday, 7th October. Students intending to compete are requested to send their names to Professor Lang by 23rd September.

Preparation for the Junior Class.-Students entering the Junior Mathematical Class are expected to know Arithmetic; Euclid, Books I. II. III. IV.; and Algebra to Quadratic Equations inclusive; Elements of Trigonometry.

Books recommended.-Mackay's Euclid, C. Smith's Elementary Algebra, and Loney's Trigonometry.

Summer work for the Junior Class. - Centres of Similitude, Coaxal Circles, Inversion, and Harmonic Section (Casey's Supplement to Euclid, or Nixon's Euclid Revised); C. Smith's Elementary Algebra (the whole of it).

Summer work for the Ordinary Class.-The work of the Class during last Session; C. Smith's Algebra; and either (a) Conic Sections, unabridged notation, to end of general equation of second degree, and including circle, parabola, ellipse, and hyperbola; or (b) Loney's Trigonometry.

Preparation for the Honours Class.-Having revised the work of the Ordinary Class, the Student should read such parts of Algebra as he has not already mastered, as contained in the latter chapters of C. Smith's or any other Algebra; then Salmon's Conic Sections, Chapters I. II. III. V. VI. VII., or Conic Sections by C. Smith, Chapters I. to IX. The Student is expected to know the rules of Differentiation and Integration, and to assist him in this he may receive, on application to Professor Lang, a series of graduated examples on Differentiation and Integration.

NATURAL HISTORY.

A Professorship of Civil History was founded in 1747. By Ordinance No. 21 of the Scottish Universities Commission of 1858, it was appointed that the Professor of Civil History should also be Professor of Natural History (which had been taught for many years) and a Member of the Medical Faculty. By Ordinance No. 48 of the Scottish Universities Commission of 1889, the designation of the Professorship was altered from Civil and Natural History to Natural History only. The Professor is appointed by the University Court.
