. One made of porcelain will answer all our purposes. Inordering, specify the 15-c.c. size with lid. Its cost is so smallthat while a fair substitute could be devised it is not worth whiledoing so as the extra care required in handling would more thanoffset the saving effected. The ringstand, shown in Fig. 6, can easily be made from;-in. iron pipe and fittings, and, being adjustable, it is moreconvenient to use than the tripod shown in Fig. 4. If a good supply of gas is available (as in almost any city) abunsen burner is the most convenient form of heater to use. Ifnot, a gasoUne blow torch, such as shown in Fig. 4, will be needed;or an ordinary plumbers or electricians torch will do nicely.The latter, however, usually gives a horizontal flame and will haveto be tilted a little in order to make the flame strike the oven orcrucible to best effect. A home-made Bunsen burner as per Fig. 7 will give just assatisfactory results as a purchased burner. To regulate the air ANALYSIS OF COAL 31

Desiccator When the moisture has all been driven off from the sample ofcoal by the first heating and the sample is dry and still hot it wouldrapidly absorb moisture from the air if left exposed to it in thatcondition. And the same thing would happen after each subse-quent heating if the sample were left exposed to the ordinary air. Hence, the sample is transferred direct from the oven or fromthe tripod to the desiccator or drier to cool off before beingweighed. The commonest form of desiccator is that shown inFig. 4. It consists simply of a glass jar and lid; the joint betweenjar and lid being ground to an air-tight fit. The lower part orwell of the desiccator is about quarter or half filled with puresulphuric acid. The upper part contains a glass or porcelain trayupon which to set the crucible containing the sample of co
