Metallurgical Laboratory. 
This Laboratory is conducted by Mr. R Smith, under the 
direction of Dr. Percy, and is devoted to practical instruction in 
Metallurgy. The nature of this instruction will be adapted to 
the special requirements of the student. It comprises, — 
Assaying in all its branches, especially of the more important 
metals, such as iron, copper, lead, tin, alloys of silver and 
gold, &c. ; and the examination of ores and metallurgical 
products. 
The ability of the student to make trustworthy assays is in 
every case thoroughly tested ; and no certificate of competency 
is given to a student who lias not furnished satisfactory proof 
that he is able to obtain accurate results. 
There are three sessions in the collegiate year, of three months 
each. The Laboratory hours are from 10 to 4 during November, 
December, January, and February ; and from 10 to 5 during the 
other months, with the exception of Saturdaj^s, when the Labo- 
ratory is closed. 
The charge for instruction in the Metallurgical Laboratory is

and seven pounds for one month.
