Chemical Laboratory. 
The general Laboratory for instruction in chemical manipu- 
lation, in qualitative and quantitative analysis, and in the method 
of performing chemical researches, is under the direction of Dr. 
Hofmann. The Royal College of Chemistby having become 
the property of the Government, its spacious and well-furnished 
Laboratories are used for the instruction of the pupils of the 
Government School of Mines. 
There are three sessions in the collegiate year, of three months 
each. The Laboratory hours are from 10 a.m. to 5 p.m., with 
the exception of Saturdays, when the Laboratory closes at two 
o’clock. 
The Laboratory instruction is necessarily adapted to the 
previous knowledge of the student, such as he may have acquired 
by attending the chemical lectures delivered at the Institution 
or elsewhere. The course commences with experimental exer- 
cises, calculated to make the pupil 'practically acquainted with 
the general properties of the simple substances, and of their 
most important compounds. The next subjects of his study are 
the analytical properties of bodies, i.c., those properties on which 
their detection, their separation from one another, and their 
estimation depend. The knowledge thus acquired is subsequently 
put into practice in the performance of a series of analyses, so 
arranged as to lead the student, step by step, from the simpler 
to the more complex cases, both of qualitative and quantitative 
analysis. Particular attention is paid to the use of the blow-
