§ 5. Non-Collegiate Students' Library.

This is a Library of books necessary for Students in the various Schools (with the exception of the Natural Science School).

It is open whenever the Clarendon Buildings are open.

There is also a Lending Library, which is open, under certain conditions, to those Students who have paid an entrance fee of ten shillings.

§ 6. The University Museum.

The University Museum consists of a large group of buildings which are wholly devoted to the study and teaching of various branches of Physical Science. It contains collections in illustration of Mineralogy, Geology, Zoology, Comparative Anatomy, Pathology; together with the necessary apparatus for Chemistry and Physics. It also contains Lecture-rooms, special Libraries, Laboratories, Dissecting-rooms, and other appliances for each class of teaching. It also contains the Radcliffe Library, which consists of a large collection of books in almost every department of Physical Science, and which is open to all who are admitted to the Museum (see p. 44).

It is divided into separate Departments, which correspond to the several Professorships of Mathematical and Physical Science, and

all of which are accessible without fee to all members of the University. Students of Physical Science who are not members of the University are admitted on the introduction of a Professor; and strangers from a distance, who wish merely to view the Museum, are admitted daily, between 2 P.M. and 4 P.M., on recording their names in the Visitors' Book.

The separate Departments are described in the following pages.

1. DEPARTMENT OF MATHEMATICS.

This Department consists of Lecture-rooms in which the Sedleian Professor of Natural Philosophy and the Savilian Professor of Geometry give lectures, the former upon Applied, the latter usually upon Pure, Mathematics.

2. DEPARTMENT OF ASTRONOMY.

The University Observatory was completed in November, 1875, and is maintained at the expense of the University. It contains a refracting telescope of 124 inches aperture and 15 feet focal length, furnished with every known contrivance for diminishing the physical labour of the observer and conducing to the accuracy of his work. It is furnished with spectroscopes and other necessary adjuncts.

The Observatory contains two reflecting telescopes of 13 inches aperture and of rare excellence, presented to the University by the munificence of Warren De La Rue, Esq., F.R.S., Hon. D.C.L. There are also several other instruments of less magnitude provided for the use and instruction of students.

This Observatory is devoted partly to the purposes of academical instruction, and partly is intended for the furtherance of original research in the various branches of Astronomical Science.

The Professor devotes at least two evenings of each week, during Term time, to the instruction of University students in Practical and Philosophical Astronomy. Other lectures are also given on subjects connected with the Lunar and Planetary theories.

The building and instruments are open on all week-days to the inspection of members of the University, between the hours of II A.M. and 2 P.M.

3. DEPARTMENT OF PHYSICS.

The Clarendon Laboratory attached to the University Museum is specially designed to afford facilities for the study of Physics. It contains the Physical Cabinet, a Lecture Theatre adapted for lectures requiring experimental illustration, and several laboratories respectively devoted to the different branches of Physics, viz. Acoustics, Heat, Electricity, Magnetism, and Optics. The instruction given is of two kinds.

First, Lecture courses, intended either to supplement the instruction given in the laboratories, or to teach students the general principles of Physics.

In general, two lectures are delivered by the Professor in each week during the Michaelmas and Hilary Terms, and other courses of lectures are given by the Demonstrators. These lectures are, when necessary, illustrated by experiments, and are designed to make as little demand as possible on the mathematical knowledge of the student; an acquaintance with the simplest elements of Geometry and Algebra being in most cases all that is required.

Upon first entering the class of the Professor of Experimental Philosophy the student is required to pay a fee of £1; he is then free during his University career to attend all ordinary lectures given by the Professor.

Secondly, the Laboratory course, intended for students aiming at Honours in Physics in the School of Natural Science, and for those requiring a thorough knowledge of the use of physical apparatus, and of the methods of accurate measurement and physical research.

In the Physical Laboratory the students work singly or in small groups, according to the nature of the instrument or method under consideration. Instruction is given to the student in the nature and use of the instruments employed, and each is then required himself to carry out experiments, or to make exact measurements suggested to him, under the superintendence of the Professor and Demonstrators.

The Laboratory is open daily from 10 A.M. to 4 P.M., but it is usual for a student to work in the Laboratory only on alternate
