Abstract
TN his experiments on the rapidity of propagation of the Röntgen rays, the French academician, M. R. Blondlot, discovered a new kind of rays, whichhe called n-rays, after the place Nancy, in which they were first observed,2 These rays are said to be emitted by an Auer burner, or better still by a Nernst lamp of 200 watt, power. Like the Rontgen rays, they are said to pass through aluminium with ease, but on the other hand to be absorbed by the slightest film of water, like the longer heat-waves.
