LABORATORIES FOR GENERAL TEACHING 23 



laboratory depicted (Fig. 6), and occupies about half its area. 

 The fittings here differ somewhat from those below, as it is 

 necessary to give each student a larger share of space and to 

 provide for certain operations not usually practised in the 

 general laboratory. The organic chemistry laboratory there- 

 fore provides for only forty workers. The other half of the 

 space contains rooms for the demonstrator, for balances, for 

 stores, and for special operations, such as combustions and dis- 

 tillation of very volatile liquids such as ether. 



The top floor is occupied by the advanced laboratory, with 

 places for one hundred students, half of whom face each way 

 toward the desk of the presiding demonstrator. A supply of 

 balances is found at each end of this laboratory, and there are 

 several rooms for special operations, such as water analysis. 



The three illustrations (Figs. 5, 6, 7) afford views of the interior 

 of the largest of the laboratories and of the chief lecture 

 theatre. 



At the back of the building there is a complete suite of rooms 

 fitted with black blinds and special sinks, and a copious supply 

 of cameras and other apparatus for a class in photography. 



The laboratories just described were designed for instruction 

 and research in pure scientific chemistry. A very large amount 

 of work of this kind has been done in the new laboratories with 

 results which have been communicated chiefly to the Chemical 

 Society of London, but a good deal has also been done in con- 

 nection with problems of a more or less directly technical 

 character. To add to the facilities already provided for extension 

 in this direction the new building in the neighbouring Prince 

 Consort Road now provides for two sub-departments, namely, 

 the study of fuel solid, liquid, and gaseous and chemical 

 engineering, that is, the design and working of chemical plant 

 for industrial purposes. It is hoped to add a third sub depart- 

 ment for electro-chemistry as soon as funds are available. 



The new buildings at present provided form part of a plan which 

 would ultimately include a building with a front and two wings, 

 leaving a space between the wings large enough to allow of the 

 erection of temporary buildings for special technical researches. 

 The wing so far constructed contains the departments for fuel 

 and chemical engineering. At the present time it consists of 

 two stories only, but the walls have been built in a very sub- 

 stantial manner, with a view to the addition of two floors above.
