THE ther:mometers. YHiile am^ standard chemical tl^eiTuometer may be utilized, athermometer graduated in degrees from 100° C. to 210° C. has beenfound most convenient. The lOO-clegree mark should^ come just at the top of the rubber stopper in the flask (IT centimeters from the bulb end of the thermom-eter), so that the rapidity of the rise in temperaturecan be watched if desirable after the Avater begins topass over. The total length of such a thermometerneed not be more than 27 or 28 centimeters. The bulbend of the thermometer should extend well in
