It ls well to remember that while we may speak of a note as having a certain pitch or frequency, we must remember that in most cases the sound is composed of harmonics which are sent out at different fre- quencies. A simple way of testing this fact is to sound a note on a piano mean- while depressing the key of the cor- responding note an octave higher or lower on the scale. If the note emitted by the first string were en- tireiy different than that of the sec- ond ng the second string would not vibrate in sympathy with the first string. In this case, however, pu will find that the second string brates without being struck when the first string is struck. Long after the first string is damped by allow ing the key to return to its original position the second string will con- tinue to vibrate, giving off a sound very similar to the first, but higher Up on the scale, and it will continue to vibrate until it dies out from lack of further power or until it is damped by allowing the ki to re turn to its original position, and thus allowing the damping mechanism to stop the vibration. | The secret behind this action is| that the second string has a funda- | mental vibration and harmonics which | are multiples of the vibration fre-| quency of the first string, or, In| other words, the fundamental vibra tion frequency of the second string | is a harmonic of the vibration fre.| quency of the first string, and is| therefore forced to vibrate in sym- pathy with the first string when the | firar string is set into vibration. Differ in Characteristies. | look very much | | Two men may lalike. Both have similar features, such s eyes, nose, mouth, etc., yet they are very easy to tell apart be- | :ause of very slight differences in | these characteristics. Similarly, two tones of the same pitch may be very different in quality because of the difference in the harmonics associated | | with each fundamental frequency. | It is possible by the use of which respond only to jcertain definite frequencies, to an |alyze sounds into the various com- | ponent frequencies and so determine the frequencies which combine to give a sound of that particular qual- | jity. to reverse | it is also possible S | % 0 97 | | , | | | g i W é § [N Noted Authority on Radio.

Now you may ask, “What has all this to do with harmonics and har monic interference in radio recep- tion?” The fact is that the action of sound | waves and radio waves is very sim- flar and the action of radio waves | can be explained by pointing back | to the more easily understood or bet ter known phenomena of sound waves. The ordinary type of transmitting apparatus, especially the old type of arc ar spark type transmitter, doss not send out a pure wave, but one consisting of the fundamental fre-| quency o which the transmitter is| tuned and harmonics of this funda- mental frequency or wave lengths. | The result is that receivers tuned to | higher or lower wave lengths cor- responding to the transmitting h monice will experience 4 certain | | | ! | will be very similar to that which would oceur if the transmitter were adjusted to the higher or lower wave length as the case may be. This interference by harmonics is not as strong as it would be if the tran: QLA T Radio Distributor Wanted Well known manufacturer of nationally ~advertised line of radio receivers and accessories has an unusually attractive ex- clusive proposition for distribu- tor to cover District of Colum. bia and Northern Virginia.

Strong Soaps No soap that is safe for toilet use will “remove’germs any better than Palmolive If guarding a good complexion is your aim, use a soap made to protect it HIS is to protect beauty seekers from some false impressions. Good complexions are too precious for experiments. There’s an idea, we are told, that some soaps combat germs; and others not. That for aseptic reasons certain soaps must be used. Soaps to “destroy” germs should be used only on advice of a physician. All soaps “remove” germs to a certain degree. No soap suitable for toilet use will “remove” germs any better than Palmolive. In your own interest, carry that in mind. For beauty’s sake, take care. Would you gamble with the good complexion it has taken you probably years to attain? In old days, women were told, “nse no soap on your faces.” For soaps were too harsh. Then Palmolive came . . . a soap made of cosmetic oils . . . a soap made to protect the skin. Women tried it, and found amazingly improved complexions and charm. Palmolive became quickly the leading toilet soap of the world. In France, home of cosmetics, Palmolive is one of the two largest selling soaps. French women have found it their ideal of a soap. That is because Palmolive is a unique creation, based on 60 years of soap study. It is made solely for the skin. Palmolive is not intended for laundry use or even fpr fine fabrics.” For to be good for those things, its cosmetic qualities would need be much reduced. And millions of good complexions be thus endangered. - As a “germ remover” no other soap suitable for toilet use is more effective. But Palmolive results don’t come from those other soaps. They don’t come from strong soaps. They don’t come from medicated soaps. Don’t expect them. And don’t take chances. To protect your beauty, use a soap made to protect it. Palmolive, we frankly grant, is not the only fine complexion soap. We know of two others. But they cost you 25 cents, while Palmolive costs but 10 cents—no more than ordinary soaps. Enormous production brings you this modest cost. \ Wash, launder, cleanse with any soap you wish. ¥ But when beauty is at stake, take care. Use Palmolive, a soap you know is safe to use. It is nature’s formula to “Keep That School« the name and wrapper. Palmolive is never sold unwrapped.
