THE HONGKONG GOVERNMENT GAZETTE, JULY 27, 1906.

(B.)-ENGINEERING SECTION.

The classes in this section are arranged to provide a two years' course in (a) the first principles of Engineering; (6) applied science; (e) practical mathematics. The classes in Practical Geometry are designed to enable students to become acquainted with the use of drawing instruments and the principles of projection as applied to mechanical drawing. The course is preparatory to the course in Machine Drawing intended for third and fourth year students.

The courses in Applied Mechanics, and Heat and Steam, are designed to give students a knowledge of the main principles applied in Engineering.

The classes in Practical Mathematics will enable students to acquire a good working knowledge of Mathematics, essential to follow the work of the allied courses in Engineering Subjects. The third and fourth years' courses in the Engineering section are included here for the purpose of indicating the course of study which a student may pursue after com- pleting the course for the first two years, but these further courses which will necessarily involve considerable expense to the Government, will not be given unless the number of students who have completed the first two years' course, is considered sufficient to justify this expenditure.

FIRST YEAR'S COURSE.

CLASS I.

Practical Mathematics.

1. Arithmetic.-The use of decimals; the fallacy of retaining more figures than are necessary, especially in calculations involving numbers which represent observed or measured quantities; contracted and approximate methods of multiplying and dividing numbers; using rough checks in arithmetical work.

Simplification of fractions; calculation of percentages expressing shillings and pence as decimals of a pound, quarters and pounds as decimals of a hundredweight, etc.

2. Algebra.--The use of formulæ when numeral values are given for the various quantities; Rules of Indices; problems leading to easy equations in one or two unknowns; easy transformations and simplifications of formulæ, and in casy cases, finding any one of several quantities in a formula when the others are given; practice in algebraic manipulation generally; the determination of the numeral values of constants in equations of known form, when particular values of the variables are given; the meaning of the expression “A varies as B"; factors.

3. Trigonometry.-Measurement of angles; meaning of sine, cosine, tangent; verify- ing simple formula; easy solutions of triangles.

CLASS II.

Practical Geometry.

Plane Geometry. The use of scales; the construction and measurement of angles in degrees and radians by the use of a protractor or scale of chords; proportional division of lines, and other illustrations of the propositions of the sixth book of Euclid; the construction of triangles, polygons, and other plane figures; reduction and enlargement of figures.

CLASS III.

Mechanics.

The course of instraction will consist of a practical demonstration of the first principles of Mechanics. Students will be given the opportunity of carrying out the experiments for themselves.

The lever; parallelogram and triangle of forces; centre of gravity of various solids; units of force, work, energy, power; specific gravities of solids and fluids; Archimedes' principle; the hydrometer.
