Practical Examination. 
Perform the following continuous series of experiments, and describe accurately 
what you observe to happen at each successive step of the work. a. Dissolve a 
portion of the substance -X in diluted hydrochloric acid and pass the liberated gas 
in excess into a slightly acidified solution of ferric chloride (perchloride of iron). 
b. Boil until free from smell, and then filter the above solution. Add to separate 
portions of the filtered liquid, carbonate of ammonia and yellow prussiate of potash 
respectively. c. Add carbonate of ammonia and yellow prussiate of potash respec- 
tively to separate portions of the original solution of ferric chloride. d. Dissolve 
another portion of the substance X in diluted nitric acid. e. Filter the solutions 
you have made of the substance X in hydrochloric acid and in nitric acid respec- 
tively, and test each filtered liquid with the following reagents :— 
1. Sulphuretted hydrogen, before and after (imperfect) neutralisation of the liquid. 
II. Chloride of barium. 7 
III. Excess of potash, and subsequent ebullition of the mixture.

LOCAL EXAMINATIONS. 
Junior Examination. 
Certificates are granted to those students who, having already passed a pre- 
liminary examination in reading, writing, English grammar, and arithmetic, have 
also passed in not less than two of the following subjects: Religious Knowledge ; 
English, Latin, or Greek; French or German; Mathematics, Natural Philosophy ; 
(two of the following departments: Chemistry and Practical Chemistry, Statics, 
Dynamics, &c., Heat ;) Zoology or Botany. No detailed schedules are issued. 
Senior Examination. 
The Examination deals with a more advanced knowledge of the same subjects 
as are included in the Junior Examination. No detailed schedules are issued. The 
following statement is made with reference to Chemistry :—‘(a) The general 
rinciple of chemical science and the facts which illustrate them. (6) Practical 
hemical Analysis. Credit will be given for well-chosen experiments, good 
observations, precisely recorded and well-drawn inferences from them. A fair 
knowledge of Inorganic Chemistry will entitle a student to pass in these divisions. 
‘The questions will relate to such compounds and reactions as are typical or 
characteristic. 
‘The following elements and their compounds are to be omitted :—beryllium, 
cesium, cerium, didymium, erbium, gallium, indium, iridium, lanthanum, molyb- 
denum, niobium, osmium, palladium, rhodium, rubidium, ruthenium, samarium, 
Scandium, tantalum, terbium, thallium, thorium, titanium, tungsten, uranium, 
vanadium, ytterbium, yttrium, zirconium. 
‘For the Junior Students, no knowledge of carbon-compounds will be expected, 
beyond the oxides of carbon, the carbonates, marsh gas, and olefiant gas. 
‘For the Senior Students, the knowledge of Organic Chemistry expected will 
be limited to cyanogen and the principal cyanides, paraffins, monatomic alcohols 
and ethers of the ethylic type, fatty acids of the acetic type.’ 
EXAMINATION FOR COMMERCIAL CERTIFICATES. 
The subjects of examination will be as follows:— 
ia 
(1) Lerrer-writine, (2) PRECIS-WRITING. 
(3) Taking notes in sHoRTHAND of passages read to the student, and extending 
the notes to produce a verbatim report. 
To pass in Section I. a student must satisfy the Examiners in J. (]) and I, (2).
