R.W. Wood: The N-Rays. In: Nature. 70. Jahrgang, Nr.1822, 29.

A somewhat detailed report of the experiments which were shown to me, together with my own observations, may be of interest to the many physicists who have spent days and weeks in fruitless efforts to repeat the remarkable experiments which have been described in the scientific journals of the past year.“
