 inside, with waste supports and earthenware valve ground in 3. 10. 



The outside dimensions are 95, 65 and 55 cm. 



."><!, 344. Movable Steel Pipe with Rose (Figure), of aluminium, very convenient and prac- 

 tical, for filling receptacles whicli cannot be easily connected up with the water-supply, 

 and for rincing, etc 



The steel pipe is connected to the supply by means of an armoured hose and by turning a knob 

 the spray piece or the rose can be connected up, or both can be cut off.

cock with draw chain and counterpoise 1. IV n 



This rose is connected to the water supply. It serves as a protection for the persons concerned 

 in making experiments in whicli an outbreak of fire may easily occur. In all cases the tendency is 

 to seek an exit, and the rose is fixed over the exit door. A simple pull of the chain sets this rose 

 working, the counterpoise causing the tap to open to its fullest extent.

50,346. Lecture Table, in the Physical Institute of the Danzig-Langfuhr Technical High 

 School (Prof. Max Wien), Figure 



The .table is 5.50 m long, 1.20 in high, and 1 m wide. The top is of oak, 40 mm thick, and 

 is composed of frame and panncllings, being coated thrice with hot linseed oil. The side that is viewed 

 (i. e., the side facing the auditorium) has an oak body, the remaining parts being pine. The table 

 has 6 lock-up drawers of various depths and 1 large double-doored cupboard. On the right-hand side 

 is a large bellows fitted for treadling, with wind pressure regulator for working acoustical instruments. 

 The table is fitted with gas, water, aspirated air, and compressed air leads. The gas lead is placed 

 in front under the table top, and has -2 gas taps of 8 mm bore, and 8 taps of usual bore. The 

 water lead is placed on the two narrow sides of the table and terminates in two iron water-standards 

 each having 3 taps. Underneath these water standards are 2 large white laboratory basins with lead 

 waste pipes. The leads for aspirated and compressed air have each 1 conical stop-cock. 



In addition, the following are fitted on the table: 2 electric leads, i. e., 1 double lead for current 

 from accumulators (to 60 amps.) and 1 double lead for power supply current to K0 amps. The accu- 

 mulator lead has 1 double-pole instantaneous switch for 60 amps, with silver fuse-strips, protecting
