44 catches, all singles
[Pg 133]
It will be seen from Table XII that in 4 cases out of 44 we caught
negatives, although it would appear from the arrangement shown in Fig. 12 that we could catch only positives. These negatives are doubtless
due to secondary rays which radiate in all directions from the air
molecules when these are subjected to the primary X-ray radiation.
