This discrepancy we by no means view lightly, and it is not without many qnalms that we find ourselves differing, even about a 2, with a man so splendidly careful in his work as Hertz has shown hbs&"se It is more than probable that he is right after all, so we explain what will then turn out to be our error in this note. Prof. Fitzgerald congratulated the authors on their suc- cess, and also pointed out that, although large oscillators give good results at distances within a few wave-lengths, yet at greater distances small ones were decidedly superior, owing to the energy of radiation varying as the 4th power of the rapidity. He had recently made experiments on electric radiations analogous to Newton's Rings, and had successfully observed the central dark spot and the first dark band. Refer- ring to Dr. Lodge's experiments, he inquired whether any traces of difikction were observed near the boundary of the bundle of rays between the lenses. Speaking of polarization- experiments, Prof. Fitzgerald said waves reflected from films of water exhibited no polarization, whereas those reflected from
