The object of tlic lectures is the communication of such in- 
struction as the student may be able to apply to the greatest 
practical advantage, when he may be subsequently engaged in 
conducting any metallurgical process. 
In these lectures the processes of extracting metals from their 
ores are fully described ; the chemical principles which they in- 
volve are explained, a detailed description is given of the furnaces 
and machinery employed, and as far as reliable information can 
be obtained the cost of production is stated. The illustrations 
consist of a very extensive series of specimens, diagrams, and 
models. Experimental demonstrations are occasionally intro- 
duced, but the time required for the satisfactory illustration by 
experiment of the chemical phenomena which occur in metal- 
lurgical process is generally so long as to make it impossible 
that in this respect the Lecturer of Metallurgy should follow the 
example of the Lecturer on Chemistry. However, in the Metal- 
lurgical Laboratory the students have the opportunity of conduct- 
ing all necessary experimental investigations. 
The lectures embrace the following subjects : — 
I. General considerations on the nature of metallurgical 
processes. 
II. On fuel. Estimation and comparison of the calorific power 
and intensity of various kinds of fuel. 
III. On the materials used in the construction of furnaces and 
metallurgical apparatus. Fire-clay, &c. Manufacture of 
fire-bricks, crucibles, &c. 
IV. Special metallurgical processes. 
a. Copper-smelting ; causes of the varieties of copper. 
b. Extraction of zinc from its ores. Brass and preparation 
of calamine brass. Various alloys of copper and zinc 
used in the arts. 
c. Lead-smelting. Refining and de-silverizing. Treat- 
ment of argentiferous copper. 
d. Smelting of silver ores. Amalgamation by the Mexi- 
can and Freiberg processes ; extraction by the Au- 
gustin and Ziervogel methods ; other methods of 
extracting silver from its ores. 
e . Treatment of gold ores. Methods of parting gold and 
silver on the large scale. Alloys of gold and silver 
for monetary and other purposes. Modes of assaying, 
with special reference to standards of common oc- 
currence.
