1. In 1896 I found that bulbs exhausted as a Crookes radiometer, when bombarded by a discharge from a Tesla inductor, produced X-rays, and X-ray photographs of the hand were then made, using only exhausted bulbs having no terminals. The bulbs had the following dimensions: 5 cm. diameter, stem 12 cm. long, 0⋅4 cm. diameter. I had from time to time noticed that when any of the exhausted bulbs were rubbed on the palm of the hand, they became luminous for a brief period while they were being rubbed.
