This paper aims to give a statement of the prt)pcrties claimed to belong to the N rays, the X~rays, the physi()logical rays and the heavy emission, with a history of the investigati~ns and ยข)i the decline of belief in the existence of these rays.
In brief the N rays were believed to increase the brightness ,)( an already luminous phosph~)rescent calcium sulphide screen ~m which they fell, while on the ~ther hand the N~rays lessened its. brightness.
Barring certain differences of penetrating p()wer, the physiological rays seemed ahout the same as the N rays. The heavy emission was held to consist of streams of matter ejected from objects, such as metals and liquids, and to be acted on b\ the attraction of the earth. It. too, made the ph~)sl)horescem screen brighten. Still another type of rays, the N., rays. has been discussed by a single writer, Breydel.6a* Blondlot discovered the X rays, the N~rays and the heavv emission; Charpentier discnvered the physiol~)gical rays. All were first observed in Nancy. It is from the name ,,{ this mfiversity town that the letter N is taken as a designation.
In the account nuw to f~)ll~)w results will be qu~ted at the valuation of the investigat~ws. No attempt will be made to avoid contradiction (~f prc)perties claimed. Because o{ their similarity it will be impossible always to distinguish sharply between the N rays and the physiolc~gical rays. *Numerals above the line refer tn the numbers ~)f 1)al, t~w in the bih}i-ography at the end nf tills article.
