In time these copper spirals willbecome dissolved by the solution used in this pipette and newtubes containing spirals will have to be purchased and put in. Into the back leg of each pipette fit a goose-neck stopper, asshown in Fig. 13, and to the goose-necks of the two pipettesfurthest away from the burette attach the rubber gas bags, asshown in Fig. 14. The object of these bags is to prevent air fromcoming in contact with the chemicals in the pipettes and spoilingthem. The chemical in the first pipette need not be so protected. The U-tubeO, Fig. 12, is next attached to the end of the header, FLUE GAS ANALYSIS 55 as shown, and the apparatus is ready to load and use. ThisU-tube has a wad of mineral wool in its open end and serves as afilter for the gases before they enter the apparatus, catching any.

I would advise all beginners to practice loading and manipulat-ing the apparatus with plain water before putting in the chemi-
