With regard to the work of table 34 it should be stated that it is always customary to make a second exhaustion to remove the water nuclei left by the first. Again but two distances (1 and 6 meters) were selected to guard against losses of efficiency of the X-ray bulb, so far as possible. The exhaustion was made during the exposure, which was always brief. At the distance D = 6 meters from the bulb, there is a terminal corona at dp = 22 cm.; at D=i meter it appears a little later at dp = 2$. (See Chapter II, figs. 24 and 25.) In fig. 45 the correspond- ing points are joined by straight lines, for convenience. 60. The same, continued. Discussion.—Experiments of the present kind are hampered by two annoying difficulties, the first being the variability of the X-ray bulb, the other the tendency of the wooden fog chambers to develop slight leaks which often pass unobserved. True, the chamber is tested by a second exhaustion after each of the coronas measured; but the unfiltered atmosphere entering anywhere is liable to.
