VIBRATIONS AND RAYS
97 of certain substances. Even the Primary Standard of Frequency apparatus of the Western Electricity Co. cannot meet this requirement. My correspondent passes on to a description of one of the most remarkable experiments yet made, which was carried out by the General Electric Company at Schenectady, New York. A one-inch cube of rock was placed between two metal plates, with a one-ounce weight placed on top of the rock. "In stepping up and stepping down the transformers, they reached a frequency whereby the rock lifted itself and the one-ounce weight a number of inches in the air ; perhaps, you would say, levitated the rock. The greatest precautions were taken to prevent any leakage or information as to this event, and the public never heard of it. Again," continues this communication, “last October, a friend of mine in Toronto, Canada, devised an instrument that actually grew gold content in a piece of quartz by extracting the content from the atmosphere. In his own words and those of the Professor of Chemistry at the Collegiate Institute of Toronto, they began with a piece of gold-bearing quartz weighing 8.2, and after treating it with changing frequencies, it weighed 10.6, a gain of 2.4. They presented the device and method to the Prime Minister of Canada as a gift. These things are
