ON TEACHING CHEMISTRY. 283 
 Chemistry.—Laws of combination, water, atmospheric air, combustion, acids, 
bases, and salts. . 
For the Senior Certificate. | Chemistry.—General principles of Chemistry, 
including calculations with combining weights. Chemistry of the more important 
metals, including testing (Roscoe’s ‘ Elementary Chemistry,’ Williamson’s ‘ Che- 
mistry for Students,’ W. Wilson’s ‘ Inorganic Chemistry’). 
For the Higher Certificate. No schedule in Chemistry, but the following books 
are suggested :—Roscoe, ‘ Lessons in Elementary Chemistry’; Fownes, ‘ Manual 
of Chemistry’; Armstrong, ‘ Organic Chemistry’; Bloxam, ‘ Chemistry Inorganic 
and Organic’; Roscoe and Schorlemmer, ‘Treatise on Chemistry’; Miller, ‘ Ele- 
ments of Chemistry.’ 
LOCAL EXAMINATIONS. 
Junior Certificate. 
D. 1.—CueEmistry. 
1. How can it be demonstrated that water is a compound substance? What 
is the difference between hard and soft water, and how is it ascertained ? Which 
is the softest natural water ? 
2. Of the following oxides, which are soluble and which insoluble in water: 
CuO, K,0, SO,, Pb,O,, CaO, SO,, HgO, Fe,O,, BaO, P,O., N,O,, Si0,. 
How could the insoluble oxides be got into solution ? 
3. Define ‘ water of crystallisation ’ and ‘ water of hydration,’ giving examples. 
: 4, What is combustion? How can it be shown that oxygen will burn with a 
ame ? 
5. In chemical nomenclature the terminations -ous, -ic, -gen, -ide, -ate, -ite 
frequently occur. Give examples of each, and explain their meaning and use. 
Senior Certificate. 
H. 1.—Cuepmistry. 
___ 1. Three yellow solids contain iodide, phosphate, and arsenite of silver respec- 
tively. How could you liberate the acids in each, and identify them ? 
2, Why is the combining weight of oxygen taken as 16 rather than as 8 ? 
3. What would be the volume in litres of 1 gramme of nitrogen measured at 
100° C. and 200 mm. pressure ? 
4, Write the formule of ferrous iodide, chromic fluoride, platinic chloride, baric 
hypophosphite, chloric acid, metaphosphoric acid. 
5. What is the difference between the specific gravity and the density of a 
body ?
