3d. Details of the acid chambers. 
4th. Details of the concentrating apparatus. 
5th. Details of extra apparatus used for the extraction of copper. 
The Drawings, in fine, will include sections and elevations^sufficient to show in 
detail all the important points in the construction and arrangement of the Works. 
II. The Estimates will give the cost of the ground, and the cost in detail, of all 
the buildings, furnaces, acid chambers, tools, etc., etc.: the cost of each operation in 
full, and also a detailed statement of the same referred to the ton of raw material, 
and to the carboy of acid. The interest on the capital invested will be calculated 
at 10 per cent, and on the Rolling Capital at 7 per cent. 
III. The Memoir will give the reasons for choice of raw material, for the adoption 
of the method employed, and for the location of the Works, with reference to raw 
material and a market, together with a detailed description of the whole process. 
Note. —These Memoirs and Promts must be written on paper 8x10, with a mar- * 
gin of one inch, and be illustrated by drawings made to scale, on paper 24x36 in. in 
siz 
igh two years. In 
the first year the students are instructed in Crystallography and the use of the 
Blowpipe. The lectures on Crystallography are illustrated by models, which the 
students are required to determine under the eye of the Professor. A collection of 
glass models and of models in wood, illustrating all of the important, actual, and 
theoretical forms, is always accessible to the students. The exercises in Blowpipe 
determination are entirely practical. Known mixtures are first given to the stu¬ 
dent to examine, and, when he is sufficiently familiar with them, unknown mix¬ 
tures aro determed. 
In the second year the lectures are illustrated by conferences, where the student 
is required to determine minerals by their physical and blowpipe characters, and, 
in the case of the metallic minerals, to determine their constituents. The student 
thus obtains a thorough knowledge of both Qualitative and Quantitative Blowpipe 
Analysis. The Mineralogical cabinet contains about 10,000 specimens, which are 
labelled and open to the public. Besides this there is a collection of about 2,000 
specimens, to which the students have unrestricted access.
