all of ebonite or glass, let into one inch iron gas pipes, so that no 

 galvanic action should be set up, as there would be between brass 

 taps and the iron, where practicable indiarubber pinch taps will be 

 used. The usual water space is reduced to a minimum, by an inner 

 core or cylinder, and the liquid used is heavy kerosene oil. A drain 

 is arranged from it to take off emptyings, &c. 



FITTINGS. 



A master key is to be provided for all doors as well as for all 

 the bench locks. A centrally placed key cupboard will be 

 provided for the keys of students' benches, to which they will be 

 required to return their keys on leaving for the day. Amongst 

 the fittings it is proposed to have a six-horse-power gas-engine to 

 provide electric light, to drive the crushing and grinding apparatus, 

 Chilian mill, blower, and exhaust, also to work the gas-liquifying 

 and freezing apparatus, centrifugal dryer, and similar appliances 

 now necessary in a modern laboratory. 



Steam chambers supplied from a large boiler are not provided, 

 on account of the little use there is for a steam boiler, the power 

 required for grinding, dynamos, &c., being obtained from a gas- 

 engine, but small moveable boilers or digesters will l^e supplied. 



A small lift is provided to avoid carrying apparatus up and 

 down stairs. All the principal doors are in two leaves, and four 

 feet wide and nine feet high, to allow glass cases and large pieces 

 of apparatus to be taken through readily. To keep out dust and 

 dirt from the corrider swing doors are placed at the ends. 



As many flues as possible have been arranged, since they are all 

 sure to be required sooner or later, and they have been so arranged 

 as pilasters as to form an essential feature in the architecture, 

 especially in the long corridors. Between the pilasters in 

 the corridors and lecture-i^ooms are placed brackets, upon which 

 it is intended to have busts of some of the more distinguished 

 founders of chemistry and the allied science, such as : — Avogadro, 

 Berthollet, Berzelius, Bunsen, Brodie, Boyle, Black, Cavendish, 

 Davy, Dumas, Dalton, Dulong, Faraday, Frankland, Graham, 

 Gay, Lussac, Hales, Hofmann, Laurent, Lavoisier, Liebig, 

 MargTaff, Mitscherlich, Petit, Priestly, Roscoe, Stahl, Stas,- 

 Scheele, Thenard, Wollaston, Wohler, &c.
