Distilled water is piped around to eachplace by -|-inch tin pipe and T3^-inch rubber tubingfrom a J-inch main, being supplied at the tern- 56 GAS AND FUEL ANALYSIS. perature of the room from bottles placed about sixfeet above the laboratory shelves. A supply of agallon per day per student should be provided. At the right of each place is fixed a sand-glass ofcylindrical rather than conical form, graduated tominutes for the draining of the burettes. The egg-timers found in kitchen-furnishing stores serve thepurpose admirably. Unknown gases for analysis are best containedm a Muencke double aspirator, Fig. 14, where they. Fig. 14.—Muenckes Aspirator. can be thoroughly mixed before distribution and con-veyed by a pipe to the central table. Finally, the laboratory should contain a stone-waresink provided with an efficient trap of the same REAGENTS AND LABORATORY. 57 material, to prevent mercury from being carried intoand corroding the lead waste-pipes. Drawers should be provided with compartments forvarious sizes of rubber connectors, pinchcocks, glasstubing, stoppers and fittings, and tools. When work-ing with the Orsat apparatus alone, three feet of shelfspace may be allowed to each student; when using thiswith another, as, for example, the Bunte, anotherfoot should be added.
