Interest Is World-wide. ‘World-wide interest has been aroused in the problem of the origin and nature of the cosmic rays, Dr. Briggs said, and despite the fact no immediate practical value may be attributed to their study, 4t would be a mistake to overlook the possibilities which may develop from such an investigation. ‘That the rays may exert some in- fluence on the weather and the electri- cal state of the atmosphere, thus af- fecting radio transmission, is a possi- bility, Dr. Briggs said.

Dr. Millikan says evidence concern- ing the cosmic rays which he will pre- sent at Atlantic City to the American Association for the Advancement of Science, December 27-31, is the most conclusive and interesting he ever has developed. “Dr. Auguste Piccard had nowhere near as precise instruments,” said Dr. Millikan in disclosing the results of his own stratospheric observations con- ducted with the aid of Dr. H. Victor Neher, designer of a new electroscope, and Dr. I S. Bowen, veteran associate in cosmic ray study. “Dr. Bowen and I have demonstrated clude the development of the magnetic | that the mechanism of cosmi¢ rays and | of the cosmic ray itself or the second: esult or offshoot of collisions bet smic rays and atoms in space was | the question | “Dr. Millikan says he has conclusive | and photographic proof that all the ob- servations are of secondary effects, or | movement of electrons, and not of the | | primary photons, which are the real | | cosmic’ rays.

It was explained that this was done in order to study the guestion of the deflection of these rays by a magnetic field. Some Rays Separated. Continuing, Dr. Briggs said: “The electromagnet used was suffi- | elently powerful to remove all electrons | approximately 1,000,000,000 _volts | energy from the cosmic ray beam. Those Tays which succeeded in getting through | the field were counted by a small Geiger | counter. “The result of 1,000 hours of observa- #lon shows about 31 rays can be de- tected in 24' hours by the counter when no magnetic fleld is present and only 21 rays get through in the same period when the electromagnet is turned on. “This indicates that 30 per cent of the rays must be either protons or elec- trons of energy less than 1,000,000,000 electron volts and the remaining 70 per | cent must either have a higher energy or be of a type of radiation such as neutrons or electromagnetic waves such as ordinary light, which cannot be de- flected by a magnetic field at all. “Cosmic rays are known to exist only Decause of their ability to affect electro- scopes and other sensitive instruments through very thick metal plates. Their exact nature at the present time is unknown, but it is certain that they possess energies of the order of hun- dreds of millions of volts. They may be electrons, hydrogen atoms (protons) or the newly discovered neutrons. ! May Be Similar to Light. “On the other hand, they may be sim- | ih' to light of extremely short wave | ength. ‘“‘Several investigators Lave tried to get some information which would help in answering the question as to which of these possibilities is correct. If they are electrons or protons traveling at very high speeds, it should be possible to deflect them in a magnetic field, pro- viding the field were sufficiently strong for the purpose. If, on the contrary, | they are wave radiation, like light or | neutrons, there wouid be no deflection, no matter how strong the magnetic field. Previous experiments of this kind by Rossi in Italy and Mott-Smith in this country have shown that ap- parently no deflection exists. Their ex- periments were carried out by permit- ting the cosmic rays to pass through | thick pieces of magnetized iron. | “The work at the Bureau of Siand- ards is in the realm of pure science | and contributes distinctly to the study of a problem of outstanding interest to sclence today. Concentrated attack is being made on the study of cosmic rays by sclentists in the service of the gov- | ernments of nearly every civilized coun- | try in the world.

Mr. Rodisky's talent showed itself in a vigorous style, decisive rhythm and general sturdiness of interpretation. The three numbers, De Beriot’s | “Scene de Ballet,” Hubay’s “Hungarian Rhapsodie” and Vieuxtemps' “Ballade | and Polonaise.” all require a brilliant | technique. This, Mr. Rodisky Supplied, | though sometimes at the expense of a mellow tone.
