APPARATUS FOR THE STI»Y OK RAIUATION 497 given off by this circuit is finally deducted from the experimentalsummation for the heat balance. Fig. 2 shows the apparatus in theprocess of construction and Fig. 3 shows it completed. The method of procedure in burning any one sample of fuel isas follows: water is circulated through the Junker calorimeter andupon the temperatures T3 and T^ becoming constant the switch isclosed thus lighting the fire and starting the motor. The fuel usu-ally begins to flame in one minute and the wire is kept hot fortwo minutes. After the first two minutes the speed of the air is. Fig. 3regulated to some definite speed so as to give a uniform rate ofburning. As soon as the fire is out the velocity of the air throughthe anemometer is increased to one hundred feet per minute andkept constant until the end of the test to cool down the tests are run until the temperature of the incoming gases Tgbecomes constant, which usually occurs at one or two degrees abovethe room temperature. Then the fan is shut down and the water 498 OISCLSSION ON PAPER—APPARATUS FOR STUDY OF HEAT RADIATION allowed to keep flowing through the Junker calorimeter until thedifference between Tg and l\ is the same as at the beginning of thetest. All thermometer and anemometer readings are taken everytwo minutes. The water is weighed at convenient times during thetest. The residue left in the lire pot is weighed after each testand deducted from the amount in the original sample in each of heat values may be made of some of the original sam-ples to obtain a basis of c
