It is evident, therefore, that this method of getting rid of the moisture is not 1altogether satisfactory. The most convenient and efficient method is fthe use of some form of heater, such as an electric heater. Theheaters, one placed at either end of the case, warm the air in the case, X-RAY EQUIPMENT 15 the plates themselves then become warm, and the moisture is drivenfrom their surface. 3.

But although the situation is as unfavorable as possible, themachine is in daily use throughout the year. Since these lines werewritten the room has been divided crosswise into two rooms by aboard partition.
