What a miracle of invention too is the prodigious nest of the Eumenes, "with its egg suspended by a thread from the roof, like a pendulum, oscillating at the lightest breath in order to save it from contact with the caterpillars, which, incompletely paralysed, are wriggling and writhing below"! Later, when the egg is hatched, "the filament is transformed into a tube, a place of refuge, up which the grub clambers backwards.
There is probably nothing in ordinary life much more difficult than to pick up and retain in the lenses of a telescope, levelled by hand, a spark of light so minute and faint as to be invisible to the unaided eye in the midst of the surrounding darkness, and the difficulty is enhanced when the attempt is made from the deck of a small vessel oscillating though ever so gently on the ridges of a long, low-running swell, and for the life of me I could not again find the feeble glimmer that had seemed to swim athwart the instrument, try as I would.
The effect upon other circularly vibrating bodies within that field of force corresponding to the action and reaction of electric currents upon one another. 3. The effect on pulsating and oscillating bodies similarly immersed, illustrating the mutual effects upon one another of magnets and electric currents.
But it must have pressed hard the philistines. And this prelude, the twenty-third, is fashioned out of the most volatile stuff. Aerial, imponderable, and like a sun-shot spider web oscillating in the breeze of summer, its hues change at every puff. It is in extended harmonics and must be delivered with spirituality.
In 1921 when he was in the 4th form at school he had bought two kits of parts from France and put them together with the help of his fellow-student George Grabinger. The kit consisted of a bright emitter triode in an oscillating circuit. The heater supply was a 4 volt accumulator, and a dozen or so dry cells, with an earphone in series, supplied the anode voltage.
That's what I call 'a safe and sane Fourth. Not bad for dull times, and yet it might be better. Anyhow, it's the hardest thirteen hundred and seventy-six dollars I ever earned." "Hard!" The merchant's lips twitched, oscillating his cigar violently. "Hard! I'll bet those fellows even bought your lunch. I suppose you mean it's the first money you ever earned." He seemed to choke over the last word.
As to the different parts of the internal mechanism, the box destined to contain the two millstones, the fixed stone and the moving stone, the hopper, a sort of large square trough, wide at the top, narrow at the bottom, which would allow the grain to fall on the stones, the oscillating spout intended to regulate the passing of the grain, and lastly the bolting machine, which by the operation of sifting, separates the bran from the flour, were made without difficulty.
The major never refused an invitation to join in a service held so laudable by the profession, and filled his glass also. And so strong was the beverage, that not many minutes had elapsed when they found it extremely difficult to take a forward move without oscillating from the line.
To use the amplified radio frequency oscillating currents or amplified audio frequency alternating currents that are set up by an amplifier tube either a high resistance, called a grid leak, or an amplifying transformer, with or without an iron core, must be connected with the plate circuit of the first amplifier tube and the grid circuit of the next amplifier tube or detector tube, or with the wire point of a crystal detector.
At the same moment, the witch began to walk round and round the cavern, coming nearer to the centre every circuit; while the head of the snake described the same path over the roof that she did over the floor, for she held it up still. And still it kept slowly oscillating.
