A glow lamp is contained in an iron housing with a ground glass pane and 4 blue glass panes 

 of various tints, the lamp being provided with plug box, plug and flexible. The frosted pane is turned 

 towards the microscope. The surface of the carbon loop should be vertical to the direction of obser- 

 vation, so as to utilise the maximum of light. 



In ordering, please state voltage of lamp. If this is not .-tat.-d. a 110 volt lamp is supplied.

This work table is designed to stand away from any support, is 2..">0 in Ions:. 1.60 m wide and 

 90 cm high. The top is of oak. 30 mm thick, beintr composed of frame and pannellings and impregnated 

 thrice with hot linseed oil. The body is of pitch-pine, and contains on each longitudinal side 6 drawers, 

 and underneath these, somewhat set back, -2 double-door cupboards with shelves and a box for waste 

 paper and the like. The table top has a reagent stand, with a housing at the right and left hand 

 sides for containing electrical measuring instruments. The table is provided with gas lead, having 

 8 stopcocks, water lead with 8 stopcocks, two of these cocks on each long side having hose unions 

 turned outwards and 1 cock with hose union turned upwards: on each of the narrow sides there is 

 1 large water tap with hose union: 2 white laboratory basins with raised back, deepened bottom, 

 overflow, and earthenware valve, height 50cm. length 50cm, projecting 34 cm: 1 transmission shaft 

 on each of the long sides driven by a small l ; , HP. D. C. motor, with 4 bearings. 1 driving pulley. 

 4 small spindle-rings each having 2 pulleys and 4 adjusting rings: 8 terminals, each 2 being mounted 

 on a marble slab: 4 marble slabs for taking measuring instruments: 2 dead-beat precision ammeters 

 for 1 to 5 amps. : 2 ditto for 1 30 amps. : 2 Voltmeters for 1 TO volts, and 2 Voltmeters for 1 to 

 10 volts D. C. The following are given in with the table: 4 sliding resistances for low currents: 4 crank 

 resistances for heavy currents and 4 pairs flexibles, 4 sets being provided with the necessary end- 

 connectors: 2 stirrer stands, driven by the shafting, and 1 stirrer with reciprocatory motion.
