[...] It is related that during certain high-frequency tests performed by Mr. Tesla one of his assistants was exceedingly stupid in carrying out instructions concerning the laboratory adjustments. The laboratory was equipped with a coil generating high voltage currents. After a time Mr. Tesla noticed that the man grew brighter and did his work better. He supposed for time that this was because the man was learning; but after watching him closely he discovered that his assistant’s quickness was much deeper than merely learning, to make the tests. His mental life had been stimulated, and instead of being slow to learn, as at first, he now showed remarkable acumen. [...]
The tests made on school children in Europe were with the Tesla apparatus, and were carried on under the supervision of Prof. Svante Arrhenius at Stockholm, Sweden. [...] The regular school work was pursued and the test lasted for six months. Frequent observations of the children were recorded to ascertain the effect of the high-frequency waves upon them. At the end of the experimental period the children in the magnetized room, according to the official report, showed an increase in stature of two and a half inches, while in the unmagnetized room the average increase was only one and one-fourth inches. The pupils in the electrified room likewise showed a weight increase and proportionate physical development greater than that of the children in the other. On the mental side, according to this report, the children exposed to the electric waves averaged 92 per cent. in their school work, as opposed to an average of 75 per cent. in the children of the other room. Fifteen pupils in the electrified room were marked 100 by their teacher, while only nine obtained perfect ratings in the other class. The report continues that the electrified children appeared generally more active and less subject to fatigue than those that were not electrified, and that the teachers also experienced from the treatment a quickening of the faculties as well as an increase of powers of endurance.
