B.— Carrying out experiments for which printed
instructions will be given in the paper, e.g. the observa-
tion of the effects of heat or of water, or acids &c. upon
the materials supplied. If a gas is evolved, the candidate
may be required to determine what it is. [Such a gas
will always be one of those referred to under Subject X.,
First Stage, and of which the properties have been demon-
strated in the lectures.]

C. — Recognition of materials which have been
exhibited upon the lecture table, and the properties of
which have been demonstrated, e.g. sulphur, iodine,
charcoal, manganese dioxide, potassium chlorate, nitre,
sal-ammoniac, &c.
D. — Quantitative experiments of a simple kind, e.g. a
metal or a salt may be supplied to be weighed, dissolved
in acid, and the amount of evolved gas measured at the
temperature of the Laboratory. Or the carbon dioxide in
a carbonate may be estimated by solution in an acid, and
observation of the loss of weight. Or determination of
the weight of one metal, such as silver, which can be dis-
placed by another, such as magnesium. Or experiments
on the neutralisation of acids or alkalies.

Second St^ce or Advanced Course.
The examinatior/ will consist of two parts :

I. A short writtf/i examination of about four questions,
with the object of 'testing the candidate's knowledge of
the theory of ordir.ary methods of qualitative analysis and
the preparation of such bodies as are enumerated in
Second Stage, Subject X.
