7. Keep a good supply of cold water running through the condenser tank. 



8. Adjust the flame so that about 20 minutes are required to reach the prescribed temperature. 



9. If the moisture content of the sample is high so that there is a tendency to boil over, lower the flame until a consider- 

 able portion of the water is distilled over. 



10. When the thermometers register the prescribed temperature extinguish the flame promptly. 



n. After the flame is extinguished, a slight gradual increase in temperature is to be expected. A sudden increase or a 

 sudden decrease of several degrees in temperature indicates that the flame was too intense during the latter part 

 of the heating, and the test should be repeated. 



12. See that there is no water in the graduated cylinder before starting the test. 



13. Read the percentage of moisture in the graduated cylinder beneath the layer of oil on top of the water. 



14. If the water which distils over is discoloured, the substance has evidently been burned, and the test should b3 repsated. 



15. When not in use keep the flasks in position in the compartments, and all connections made as for making a test. 



16. Before making a test in a new flask, run a preliminary sample so that all of the flasks will be in uniform condition. 



17. Draw all samples carefully and keep them in air-tight containers until ready to make the test. They lose moisture 

 rapidly when exposed to the air. 



18. Place the scales on a firm support and see that they are in balance before making a weighing. 



19. The specific instructions for making tests, as given, do not apply to modified forms of testers.
