pipe, and tlie various methods of testing and estimating the 
value of commercial and industrial products, alkalimetry, 
chlorimetry, and volumetrical analysis in general. 
The fundamental studies in Practical Chemistry are the same 
for all pupils, however different the future pursuit may be to 
which the knowledge obtained will be applied. It is only after 
the most important methods of distinguishing, separating, and 
estimating substances have been mastered, and after sufficient 
practice and skill in experimenting have been acquired, that the 
course of each student diverges into some special line. This will 
of necessity vary with his abilities and his ultimate objects. 
Each laboratory student works independently, there being no 
classes. All operations are superintended by the Professor and 
his Assistants. A table with drawers, cupboards, and shelves, 
is appropriated to every pupil. The Institution supplies gas, 
fuel, and reagents. The larger and more expensive instruments 
of the Laboratory, such as air-pumps, thermometers, barometers, 
condensers, &c., may be used by the students, who are held 
responsible for their safety. The students have to provide them- 
selves only with the apparatus specified in the Laboi^itory 
regulations. More advanced students engaged in private re- 
searches have to supply themselves with such materials as are 
not included amongst the ordinary reagents of the Laboratory. 
REGULATIONS OF TIIE LABORATORY. 
I. Each student on entering deposits ten shillings, in return for which he receives 
the keys of his table and closet, and also a set of reagents. On delivering up the 
keys and the set of reagents, after the completion of the period of his study, the deposit 
is returned.

apparatus, consisting of the following articles : — ■
