To receive wireless telegraph signals, however, from a transmitter that uses an arc or a vacuum tube oscillator and which sends out continuous waves, either the transmitter or the receptor must be so constructed that the continuous waves will be broken up into groups of audio frequency and this is done in several different ways. The heterodyne method will be described in this chapter.
From the windows the Square was visible, and at the windows Angelina spent a great deal of her time, but her present nurse nurses succeeded one another with startling frequency objected to what she called "window-gazing." "Makes a child dreamy," she said; "lowers her spirits." Angelina was, naturally, a dreamy child, and no amount of nurses could prevent her being one.
Not content with simply availing themselves, for the convenience of classification, of those gaps and chasms which here and there interrupt the continuity of the chronological series, as at present known, they deduce, from the frequency of these breaks in the chain of records, an irregular mode of succession in the events themselves, both in the organic and inorganic world.
I listened to the conversation of groups of men whose lives had been mostly spent in the army, as a rule in guerilla warfare, and the talk turned with surprising frequency to the subject of cutting throats.

The Indians, however, continued friendly with him and visited him with frequency. But when Rima grew up, developing into that mysterious woodland girl I found her, they became suspicious, and in the end regarded her with dangerously hostile feeling.
There was little communication in words between the two boys, for the one had not much to say, and the pondering fits of the other grew rather than relaxed in frequency and intensity. Yet amongst chance acquaintances in the town Robert had the character of a wag, of which he was totally unaware himself.
"'Tis probably a wandering of the reasoning powers, created by the frequency of intoxicating drafts," observed the surgeon, as he deliberately threw his left leg over the pommel of the saddle, and slid down on the right side of his horse.
